Bilayer Glass Foams with Tunable Energy Absorption via Localized Void Clusters

The research in this article entails the design of materials systems and tunable energy absorbing properties respond to a range of energy absorption needs in different impact conditions. Tunable energy absorption of bilayer cellular foams is investigated using hollow glass spheres with different wall thickness and densities. Co‐cured bilayer foams are prepared through sintering of the spheres, and their microstructures and mechanical responses to quasistatic uniaxial compression are investigated. Co‐cured system exploits localized voids density (>50 μm) locally at the interface which is induced via different shrinkage rate of spheres, leveraging tunable energy absorptions. Mechanical testing shows that the voids at the interface lead in the sequential collapse of the layers, resulting in a distinctive two‐step stress–strain profile. For comparison, bilayer samples are fabricated using epoxy. These samples show a different mechanical response from the co‐cured sample by not showing the two‐step stress–strain. The co‐cured samples exhibit 14.8% more specific energy absorption than epoxy bonded samples. The results suggest that co‐cured samples can limit impact stress and achieve a higher energy absorption capacity than epoxy bonded samples. The manufacturing concept and system design expand the capabilities of cellular foams, yielding desired energy absorbing properties in a diverse range of applications.

The coupled model of wellbore temperature and pressure for variable gradient drilling in deep water based on dynamic mass flow

Variable gradient drilling in deep water is a new drilling method of using separators to separate hollow glass spheres (Referred to as HGS, it is the glass microbeads with low density less than 1.0 kg/m3, and the worse thermal conductivity) from the drill string directly into the annulus, which can form multiple gradients of drilling fluid density in annulus. This method can better deal with the problem of narrow pressure window in deep water drilling. At present, there are few studies on the wellbore temperature and pressure distribution of this technology, and the separation efficiency of the existing separator is too low to achieve variable gradient. The purpose of this paper is to develop a new separator to improve the separation efficiency, and to study the coupled wellbore temperature and pressure field of variable gradient drilling based on dynamic mass flow. Firstly, indoor simulated experiments were used to study the separation efficiency of the newly developed filter separator, and based on the separation efficiency, wellbore flow theory and the first law of thermodynamics, the dynamic mass flow at the location of the separator were fully considered. Considering the influence of wellbore temperature and pressure on thermophysical parameters, a coupled model of wellbore temperature and pressure was established based on dynamic mass flow. Then the model was discretized and solved by finite difference method and cyclic iterative algorithm. Further, this model was verified based on the existing models and drilling site data. Finally, the effects of key parameters in variable gradient drilling on the annulus temperature, pressure and fluid density were studied. The results show that the filter separator has high feasibility, and the separation efficiency can reach 95%–98.5%. Compared with conventional drilling, distribution curve of the temperature, pressure and the mixture density in annulus of the filter separator section has obvious inflection points in variable gradient drilling, and the number of inflection points is equal to the number of separators. What's more, the number and location of separators, the HGS volume fraction, pump flow rate, and the HGS density have significant effects on the annulus temperature and pressure. This research can significantly improve the feasibility of variable gradient drilling in deep water and provide a theoretical reference for further research in this direction.

An Experimental Assessment of Iraqi Local Cement and Cement Slurry Design for Iraqi Oil Wells Using Cemcade

This effort is related to describe and assess the performance of the Iraqi cement sample planned for oil well-cementing jobs in Iraq. In this paper, major cementing properties which are thickening time, compressive strength, and free water in addition to the rheological properties and filtration of cement slurry underneath definite circumstances are experimentally tested. The consequences point to that the Iraqi cement after special additives encounter the requests of the API standards and can consequently is used in cementing jobs for oil wells. At this research, there is a comparative investigation established on experimental work on the effectiveness of some additives that considered as waste materials which are silica fume, bauxite, and glass powder, and other conventional additives which are: (SCR -100 Retarder, HR-5, FWCA, Hollow Glass Spheres (HGS) and Halad-9) that currently used in our fields on local Iraqi cement and putting foreign cement results as a governor. Chemical analysis for Iraqi cement, imported cement, and waste materials samples was determined using the X-ray fluorescence (XRF) technique and found minor differences in composition between those samples and depending on the results of X-ray, we selecting the appropriate additives to prepare cement slurry samples. The X-ray fluorescence (XRF) results show that Iraqi Cement has a low value of silica which is about 18.63% while Omani cement about 37.58%. This research examined the potential of micro silica, bauxite, and waste glass powder to produce sustainable cement slurry. The results showed that adding micro silica and bauxite enhances the performance of Iraqi cement but also leads to a slight decrease in thickening time. To avoid this problem, Superplasticizer is used to make the process of cement pumping more easily, in other words, increase thickening time and increase compressive strength. Furthermore, adding glass powder increase the value of compressive strength. Both additives (waste and conventional) are used for the slurry design for achieving better slurry properties, but waste additives increase and enhance Iraqi cement performance than conventional additives, in other words, making it more effective than commercial cement. Depending on the results of the compressive strength test, the optimal concentration of the waste materials used in this research was found, and then the optimal concentration was used to prepare cement samples. The results showed that the use of waste materials to prepare cement slurry is a promising way to improve the efficiency of cement work and to reduce the negative environmental impact resulting from the industry. The results of the program CemCADE proved to be the sample A and C showed good performance through high cement bonding and ideal distribution of fluids designed to accomplish the cementing process.

Experimental and Numerical Study on the Heat Transfer Characteristics of a Newly-Developed Solar Active Thermal Insulation System

A newly-developed solar active thermal insulation system (SATIS) is introduced with the main objective to accomplish a highly-dependent total solar transmittance on the irradiation angle. SATIS is also designed to obtain the maximum transmittance at a prescribed design irradiation angle and to reduce it remarkably at higher irradiation angles. A purely mineral thermal insulation plaster with micro hollow glass spheres is applied to manufacture the investigated SATIS prototype. Light-conducting elements (LCEs) have been introduced into SATIS and suitable closing elements have been applied. The SATIS prototype has been investigated both experimentally and numerically. It turned out that the contributions of conduction, radiation and convection to the effective thermal conductivity of SATIS, without the closing elements (49 mWmK), amount to 86.2%, 13.2% and 0.6%, respectively. The angle-dependent short-wave radiation exchange within the LCE has been investigated via ray tracing. At the incidence angle of 19% (design angle), 27% of the radiation within the LCE is absorbed by the absorber plate, resulting in measured and computed total solar energy transmittances of 11.2%/11.7%, respectively. For a typical summer irradiation angle of 60%, 98% of the incident radiation is absorbed by the surfaces at the entrance of the LCE. The corresponding total solar energy transmittance amounts to 2.9%.

Self-stratifying amphiphobic coating based on functional polyacrylates

Self-stratifying coating is a promising and interesting coating system containing multi-resinous components, which instinctively stratify after coating on the substrate. Here, we have developed a new type of self-stratifying coating based on functional polyacrylate system. In this case a terpolymer of butyl acrylate, acetoacetoxy ethyl methacrylate and hydroxyethyl methacrylate was used as the polymer matrix. The whole coating system consists of a blend of a functional acrylic terpolymer (bearing acetoacetoxy, n-butyl as well as hydroxy ethyl functional group as the pendant group), phenyl methoxy functional siloxanes, hollow glass spheres (HGS) and aerogel particles (AP). 3-aminopropyl triethoxysilane was used as a crosslinker. Hydrophilic hollow glass spheres (of 20 μm average particle size) and hydrophilic aerogel particles (of 5 μm average particle size) were used to generate desirable roughness on the surface. Low quantity of a non-silanated fluorinated surfactant was incorporated, which self-stratifies to the surface during coating film formation and imparts oleophobicity. An oil and water repellent (amphiphobic) surface was developed with high water as well as diiodomethane contact angle (∼130°) by varying the ratio of glass spheres and aerogel to each other and the polymer. Rolling effect of water and oil drops was also prominently visible. The surface showed excellent resistance to polar and non-polar solvents, good resistance to heat (150 °C) and sand impingement after which the water contact angle remains unchanged. The oil repellency was easily restored by spraying or dipping in a dilute solution of the non-silanated fluorinated compound. This coating can be applied by conventional techniques such as spray application and can have potential applications in anti-soiling and self-cleaning coatings.

A new particle for measuring mass transfer in turbulence

We present a method for creating a new type of model particle that allows us to measure the mass transfer rate from the particle surface to the surrounding water. We use hollow glass spheres and sugar to create neutrally buoyant particles in a variety of molded shapes. These particles are an alternative to traditional gypsum objects for measuring mass transfer, with the important characteristic of being neutrally buoyant. This is an inexpensive method that allows for custom particle shapes to be manufactured with different densities. We test the utility of these particles by measuring their dissolution rates in homogeneous, isotropic turbulence in our laboratory turbulence tank. Our measurements fit our proposed model, and give a faster dissolution rate for rod-shaped particles than for disc-shaped ones.Graphic abstract

ЧИСЛЕННОЕ МОДЕЛИРОВАНИЕ УПРУГОГО ПОВЕДЕНИЯ СИНТАКТОВЫХ КОМПОЗИТОВ НА ОСНОВЕ ПОЛЫХ СТЕКЛЯННЫХ МИКРОСФЕР ПРИ РАСТЯЖЕНИИ

Using the universal software package “Solid Works”, on the example of a cubic model of a composite based on hollow glass microspheres (HGM), numerical simulation of the elastic behavior of a syntactic material under uniaxial tension is carried out. The chosen computational model is a hollow thin-walled glass sphere placed in a polymer (epoxy) matrix of cubic shape. The model was calculated using the finite-element method in an elastic approach with boundary conditions defined by the used universal software system of 3D modeling of the “Solid Works” complex. The calculations made it possible to determine the longitudinal and transverse elastic strains for the model of a syntactic composite with different contents of the initial components and then to calculate the value of the elastic modulus and the Poisson's ratio under tension for these materials. Experimental verification of the calculations performed was carried out on samples of syntactic composites based on epoxy binder and HGM of type MC-ВП A9 2 gr. A size group of microspheres with a diameter of 50 to 70 microns was isolated from the initial HGM by sieving method. The average diameter of these microspheres was about 59 microns. On the basis of the microspheres selected in this way, samples of epoxy composites with different volume contents of components (30%, 40% and 50% HGM) were made and their actual elastic characteristics under tension were measured. The results of experiments to determine the elastic characteristics of syntactic composites correlate well with the calculations, especially for composites with a filling coefficient of 0.45–0.5 with hollow microspheres.

The new indicator coating to detect the place of barely visible impacts on aircraft composite structures

There was developed indicator coating made of epoxy resin filled with hollow glass spheres of the volume fraction up to 50% on GFRP substrates. This coating has a high sensitivity to local impacts changing light reflection by the failure of epoxy and glass spheres in the contact area. Mechanical behaviours of the coating are close to the pure epoxy resin but the density is twice less. We also provided experimental data concerning the contact traces under barely visible impact and the numerical model to predict residual traces onto indicator coating with GFRP substrate.

Hollow glass spheres in sheet molding compound composites: Limitations and potential

AbstractSheet molding compounds (SMC) are commonly used in automotive applications as they lead to increased fuel efficiency of vehicles due to their high strength to weight ratios. This study focuses on understanding the effect of replacing calcium carbonate (CaCO3) with hollow glass spheres (HGS) in an unsaturated polyester resin matrix SMC composite with the ultimate goal to further reduce density without compromising performance. The resulting glass fiber (GF)‐reinforced syntactic foam laminate composites with GF content ranging from 10 to 15 vol% have densities of 1.2 and 1 g/cm3, respectively. This is significantly lower than the industry standard SMC density of 1.9 g/cm3. The HGS parameters of interest are primarily HGS type (S28HS and S32HS), loading level (33–44 vol%), and surface functionalization (methacrylsilane). The syntactic foam composites were characterized in terms of tensile, flexural, and impact properties, and their properties were compared to those of standard density SMC. As expected, the flexural, tensile, and impact properties were compromised with a decrease of density. However, they were higher than the corresponding properties of low‐ and ultra‐low density composites reported in the literature, as we were able to add higher GF content in these low‐density SMC formulations. It was also concluded that methacrylsilanized surface treated HGS showed promise in maintaining the mechanical properties, especially at high sphere loadings. The impact energy of the low‐density formulations was relatively unaffected by HGS type or loading.

Experimental and numerical study on the solar gain and heat loss of typical existing and refurbished German buildings

This communication introduces an experimental setup for investigating the effect of solar radiation on the reduction of transmission heat losses and the steady state thermal conductance of uninsulated and insulated multi-layer wall samples. The setup consists of two adjacent climatic chambers, which share a common wall, in which the multi-layer wall samples are mounted. A solar simulator is applied within the outdoor air climatic chamber, whose radiation spectrum and radiation intensity are approximately equivalent to those of the sun. The first tests have been carried out on a wall sample with a typical structure of existing buildings from the year 1930 in Germany. In addition, a high-performance insulating plaster layer has been applied on a basic test sample (with existing building structure) to replicate and assess the refurbished scenario. Furthermore, a numerical investigation on the transient heat transfer process is carried out by using the simulation software COMSOL Multiphysics®. The experimental results of both uninsulated and insulated wall samples are validated against 1D and 3D models. As seen, the uninsulated wall, whose thermal conductance was experimentally determined to be equal to 1.79 W/(m²K), absorbs a heat flux of 208 W/m² through its external wall surface over a period of 8 hours. A fraction of 9.8 % of the absorbed heat arrives as a gain on the internal wall and reduces the transmission heat losses by 11.7 % over a period of 55 hours. On the other hand, the thermal conductivity of the insulation layer of the refurbished wall sample with micro hollow glass spheres was estimated by a parameter estimation procedure using the 3D model and the obtained experimental data. Using the estimated thermal conductivity, a thermal conductance of 0.42 W/(m²K) has been obtained for the refurbished wall sample.

Non-Brownian Newtonian suspensions may be rate dependent in time sweep oscillatory shear flow

A non-Brownian, inertialess, dense suspension of rigid hollow glass spheres is studied with time sweep oscillatory experiments. The measured apparent complex viscosity is shown to depend on the amplitude of the applied strain, in agreement with the literature, and, unexpectedly, also on the angular frequency. Two different regimes are individuated depending on the applied strain. For values smaller than 1, when the structure evolution is driven by the shear-induced diffusion, the complex viscosity depends on the frequency, for values larger than 1, it is rate independent. In the first regime, the dependence on the applied strain amplitude and the angular frequency can be lumped into a single parameter: The maximum shear rate, the applied strain amplitude times the angular frequency. The results obtained are quite surprising since in a non-Brownian, inertialess, dense suspension, the particle interactions do not have a characteristic time scale and, consequently, the governing equations of motion result rate independent. Only the presence of a nonhydrodynamic force can introduce a characteristic time. We observe that this nonhydrodynamic force must be so small to be neglected in simple shear, since the behavior of the investigated suspension in the steady shear flow is found to be rate independent, and it must show its effects only in oscillatory experiments with strain amplitude smaller than 1. The frequency dependence is also observed with two less concentrated suspensions and all the data collapse on a single master curve, proving that the physics underneath the rate dependence is independent of the concentration.

Multiscale damage analysis of the tension‐tension fatigue behavior of a low‐density sheet molding compound

AbstractThis article presents the experimental findings of tension‐tension stress‐controlled fatigue tests performed on low‐density sheet molding compound (LD‐SMC). LD‐SMC composite is a type of SMC including a polyester resin reinforced with chopped glass fibers bundles and hollow glass spheres. The coupled frequency‐amplitude affects the nature of the overall fatigue response, which can be controlled by the damage mechanisms accumulation and/or by the self‐heating. In fact, the self‐heating produced a material softening and decreased the fatigue lifetime. For fatigue loading at 80 Hz, self‐heating has been observed and yielded to a temperature rise to 65°C, which is more than a glass transition temperature of polyester. Thus, the polyester matrix is subjected to remarkable thermally activated modifications of its physical state. Multiscale damage analysis of the randomly‐oriented sample in fatigue showed that the first observed damage phenomenon corresponds to the debonding of the hollow glass microspheres occurring in the fiber depleted zones.

The effects of water-based insulation paint applied to laminate flooring panels on the thermal conductivity coefficient and adhesion resistance

In an effort to reduce negative feedback resulting from temperature fluctuations, house floors are commonly laid with laminate flooring. The aim of this study was to study the thermal insulation properties and adhesion strength of the water-based insulation paint mixed with hollow glass spheres and applied onto the laminate flooring. The objective was to determine whether a prepared insulation paint mixture can be used instead of backing paper. For this purpose, two different laminate flooring samples were used. In the first case, the upper surface of the sample was coated with decorative paper and the lining surface was coated with backing paper. The upper surface of the second sample was coated with decorative paper and the lining surface was not coated with backing paper. Then, insulation paint mixture was applied 2, 4, or 6 times to the lining surfaces of both groups, and experimental results were obtained. As the number of layers was increased, the insulation mixture applied to the lining surfaces of the test samples was found to contribute positively to thermal insulation and adhesion resistance of specimens.

Thermal, structural and dynamical mechanical properties of hollow glass sphere-reinforced polypropylene composites

In the present study, the effect of maleic anhydride grafted polypropylene (MAPP) ratio on the thermal and dynamic mechanical properties of polypropylene/hollow glass spheres (PP/HGS) composites was investigated. Hollow glass spheres content was constant at 20 wt % and MA-g-PP was set at four different levels: 1, 5, 10 and 15 wt % in PP/HGS composites. The mechanical properties of polymer composites as a function of temperature were measured using dynamic mechanic analyzer. The oxidation induction times tests and thermal properties were carried out in thermogravimetric differential thermal analyzer in order to determine thermo-oxidative performance and thermal stability of the composites. Moreover, the x-ray diffraction (XRD), the Fourier transform infrared spectrophotometry and the scanning electron microscopy were used to analyze the structural characteristics of the polymer composites. The results demonstrated that the increased MAPP content enhanced dynamic mechanical and thermal oxidative aging properties of PP /HGS composites. The addition of MAPP did not alter the crystal structure according to XRD results.

Experimental investigation on adhesively bonded U-shaped metallic joints using the Arcan test

An experimental investigation on adhesively bonded joints has been carried out by using an adhesive used in automotive applications. The main goal of this work is to characterize the mechanical behaviour of the adhesive joints subjected to different loading angles and understand whether the cataphoresis painting process can be used to cure the adhesive. To this aim, two different typical temperatures, used for the cataphoresis process, have been used for curing the studied adhesive. Arcan test has been used to characterize the mechanical behaviour of the adhesive joints by using five different loading angles: 0° (shear condition), 30°, 45°, 60° (combined shear-tensile), and 90° (tensile). The experimental tests showed that the adopted curing cycles conducted at 190 °C for 15′ and 160 °C for 45′ are both able to fully cure the adhesive, this was verified with Differential Scanning Calorimeter analysis (DSC). The two curing temperatures do not lead to significant differences in the maximum values of the strength. Arcan test conducted at different loading angles shows that the maximum value of the strength is obtained for the condition of shear loading (about 10 MPa nominal strength), while the lowest value is related to the condition of tensile loading (about 5 MPa nominal strength). Scanning Electron Microscope (SEM) analysis was used to assess the distribution of the hollow glass spheres that are embedded in this adhesive to set the thickness layer.

Survival of hollow glass microspheres in drilling fluids applications – Effect of drill bit/formation contact

This study concentrates on materials called hollow glass spheres (HGS), also known as glass bubbles, which are used to reduce the drilling fluid density below the base fluid density and overcome the shortcomings of compressible drilling fluids. The most important physical properties of the microspheres for oil field applications are their low specific gravity and high collapse strength. The lower the specific gravity, the greater their density reduction capabilities, meaning that less product is required to achieve the drilling fluid target density. High crush strength (and/or survivability) is equally important, as maintaining the target density is key to achieve and maintain bottom hole pressure control.The performance of drilling fluids made with HGS was evaluated for different drilling weight on bit (WOB) and rotation speed (RPM) values while controlling the flow rates. Experimental results show that when the HGS particles are subjected to mechanical contact between bit and formation, they will break. However, it was observed that the majority of HGS will not be exposed to contact between the cutter element and formation. Instead, they pass through the nozzle exit, leave the bit face region in a short period of time, and go directly into annulus, with minimum time of expose for contact. A mathematical model was developed to quantify the amount of HGS that become in contact between bit and formation, depending on various operational parameters, including effective blade length, flow rate and RPM. Finally, results from experiments and estimation models were compared, suggesting that the studied HGS successfully reduce the density of the base drilling fluid, and can survive the tested conditions.In summary, reducing the density of liquid based incompressible drilling fluids with glass bubbles is an alternative to available compressible underbalanced drilling fluid options at depleted zones or offshore wells with a very narrow density window.

Synthesis and Characterization of Hollow Glass Sphere Containing Aluminum Syntactic Foam by Spark Plasma Sintering and Hot Pressing

The effect of sintering process on the microstructure and the mechanical properties of aluminum syntactic foam were investigated in this study. Two different sintering processes of spark plasma sintering and hot pressing were used. Glass hollow spheres with a size of 50–80 μm was used to fabricate the foams having various volume fractions of the spheres in the range of 10–30%. Microstructural analysis revealed that the glass hollow spheres were uniformly distributed in the aluminum matrix, both in the spark plasma sintered and hot pressed ones. As the volume fraction of the spheres increased from 10 to 30%, the density, micro-hardness and compressive strength of the foams were decreased. In comparison to the foams fabricated by hot pressing method, the spark plasma sintered foams had slightly lower density and mechanical strength. In nanoindentation study, it was found that the aluminum matrix in the foam prepared by the spark plasma sintering process had lower strength than foam prepared by the hot pressing process. This is likely because of shorter sintering time used in the spark plasma sintering process than the hot pressing.

Microstructural characterization and compression mechanical response of glass hollow spheres/Al syntactic foams with different Mg additions

Aluminum syntactic foams with different magnesium contents were fabricated by pressure infiltration of glass hollow spheres. Effect of Mg addition on microstructure, compression properties and corresponding deformation behavior as well as energy absorption under different strain rates loading was experimental investigated. Increasing Mg contents resulted in interface reactions between matrix and glass spheres forming MgAl2O4, Si and Mg2Si hard phases, leading to the improvement of compression strength, structural stiffness and energy absorption capacity of syntactic foams, however, reducing the strain rate sensitivity of the syntactic foams. The addition of Mg content decreased the stress relaxation and load transfer ability of the matrix and developed the syntactic foam into severe brittle fracture during quasi-static compression. Nevertheless, the influence of Mg addition on the macroscopic compression deformation behavior of syntactic foams was weakened at increasing high strain rate loading.

Design, modeling, and experimental validation of an acoustofluidic platform for nanoscale molecular synthesis and detection.

Microfluidic technologies are increasingly implemented to replace manual methods in biological and biochemical sample processing. We explore the feasibility of an acoustofluidic trap for confinement of microparticle reaction substrates against continuously flowing reagents in chemical synthesis and detection applications. Computational models are used to predict the flow and ultrasonic standing wave fields within two longitudinal standing bulk acoustic wave (LSBAW) microchannels operated in the 0.5-2.0 MHz range. Glass (gLSBAW) and silicon (siLSBAW) pillar arrays comprise trapping structures that augment the local acoustic field, while openings between pillars evenly distribute the flow for uniform exposure of substrates to reagents. Frequency spectra (acoustic energy density E ac vs frequency) and model-predicted pressure fields are used to identify longitudinal resonances with pressure minima in bands oriented perpendicular to the inflow direction. Polymeric and glass particles (10- and 20-µm diameter polystyrene beads, 6 µm hollow glass spheres, and 5 µm porous silica microparticles) are confined within acoustic traps operated at longitudinal first and second half-wavelength resonant frequencies (f 1,E = 575 kHz, gLSBAW; f 1,E = 666 kHz; and f 2,E = 1.278 MHz, siLSBAW) as reagents are introduced at 5-10 µl min-1. Anisotropic silicon etched traps are found to improve augmentation of the acoustic pressure field without reducing the volumetric throughput. Finally, in-channel synthesis of a double-labeled antibody conjugate on ultrasound-confined porous silica microparticles demonstrates the feasibility of the LSBAW platform for synthesis and detection. The results provide a computational and experimental framework for continued advancement of the LSBAW platform for other synthetic processes and molecular detection applications.
