Investigation of agricultural waste and ZrB2 nanoparticles with reinforcement in aluminum alloy matrix

Agricultural waste has the potential to serve several purposes, such as reinforcement. In recent times, researchers have incorporated agricultural waste into various materials with the aim of enhancing their qualities. By acting as a kind of reinforcement, it has the potential to decrease the quantity of agricultural waste that needs further processing. This work enhances the area of advanced materials by examining the characteristics of Al 7175 alloy reinforced with zirconium diboride (ZrB2) nanoparticles and rice husk ash, which is a byproduct of agriculture. Understanding and improving the wear resistance of composites is crucial in several industrial applications. This study involves the incorporation of ZrB2 nanoparticles into the Al 7175 alloy at three distinct concentrations, with the addition of 2.5 % rice husk. This study examines the correlation between wear parameters and responses (Cf), including friction force (FF), wear rate (Sf), and friction coefficient. Sliding distance, load, composition, and speed are among the wear parameters. The aforementioned combinations result in a load of 25.2 N, a rotational speed of 400 rpm, a sliding distance of 71.2 m, and a composition of 5 %. Taguchi signal-to-noise ratio (SNR) analysis is used to identify optimal combinations for minimizing Cf, Sf, and FF. Confirmation tests are conducted in order to ensure that the results align with the expected optimal combinations. Data scientists may also use an Artificial Neural Network (ANN) model as a valuable tool. It utilizes input data to forecast replies. The ANN model demonstrates strong performance throughout testing, validation, and training, with an overall prediction rate of 87.873 %. The study's results indicate that reducing the load and speed, while increasing the concentration of ZrB2 nanoparticles, may effectively decrease the wear rate. In addition, the use of rice husk enhances the wear resistance of the base alloy by 28 %. The alloy Al 7175 may experience a reduction in wear rate and friction coefficients by the incorporation of 2.5 % rice husk and 5 % ZrB2 nanoparticles.

A critical review on the effect of various sustainable reinforcements on armor grade aluminum alloys

To deflect projectiles with kinetic energy by blunting them upon impact, armor with an exceptionally hard surface is required.In order to absorb and disperse the projectile's kinetic energy, the next material needs to be exceedingly tough and have a high work of fracture; hence, it needs to be metallic. To maximize the strength to weight ratio, it must also be composed of a versatile material, such as ceramic. Thus, the application requires a range of qualities, ranging from ceramic to metallic. Aluminum alloys (AAs) are sought-after materials for a variety of engineering and defense uses owing to their excellent low-temperature characteristics, good specific strength, and acceptable corrosion resistance. The main issues with AAs are poor heat tolerance and wear resistance, which makes them unsuitable for military applications owing to their heavy weight, which can exacerbate the deterioration of mechanical components and impair vehicle maneuverability and speed. This paper offers the possibility of modifying the properties of monolithic aluminum materials by adding reinforcement and replacing conventional particulates with low-cost wastes derived from agriculture and industry, which are rich in oxides and other debris, such as fly ash (FA) and rice husk ash (RHA). The result is the development of hybrid aluminum metal matrix composites, or HAMMCs, which combine the best features of both metals with a variety of sustainable inorganic and organic reinforcements that can enhance the mechanical and tribological performances by 40–62 % in comparison to the basic matrix. So, they can be tailored to meet the needs that make their performance superior compared to unreinforced AAs. Through a review of existing literature, this paper will provide an outline of the effect of various kinds of reinforcements on armor-grade aluminum alloys.

The aim of this research is to examine the performance of reinforced lightweight ferrocement walls under vertical and horizontal loading. The walls were made up of two thin layers of ferrocement reinforced with one, two, three, or four layers of welded wire mesh or expanded steel mesh. The panels’ core was constructed of lightweight extruded foam. An experimental program of thirteen lightweight walls with total dimensions of 100x650x1250 mm was casted to achieve this goal and tested until failure. ABAQUS finite-element package was conducted. The parameters in this study were the kind of reinforcement; welded and expanded wire meshes, the steel bars, and. the number of layers of steel mesh. Ultimate load, mode of failure, initial cracking load, service load, energy absorption, and ductility ratio were calculated and observation to evaluate the findings. The findings displayed that the performance of the ferrocement walls reinforced with expanded wire meshes is better than that of the walls reinforced with welded wire meshes. The energy absorbed increased by 40 % for specimens reinforced with expanded wire meshes is more than that of the walls reinforced with welded wire a good agreement was observed among the theoretical and experimental observations. This paper highlights uses of employing light weight ferrocement units in building of economic housing, which is particularly valuable for both developed and developing nations, with significant frugal benefits.

Seamguard Buttressing of the Staple Line During Laparoscopic Sleeve Gastrectomy Appears to Decrease the Incidence of Postoperative Bleeding, Leaks, and Reoperations. A Systematic Review and Meta-Analysis of Non-Randomized Comparative Studies.

Leaks and bleeding are major acute postoperative complications following laparoscopic sleeve gastrectomy (LSG). Various staple line reinforcement (SLR) methods have been invented such as oversewing/suturing (OS/S), omentopexy/gastropexy (OP/GP), gluing, and buttressing. However, many surgeons do not use any type of reinforcement. On the other hand, surgeons who use a reinforcement method are often confused of what kind of reinforcement they should use. No robust and high-quality data supports the use of one reinforcement over the other or even supports the use of reinforcement over no-reinforcement. Therefore, SLR is a controversial topic that is worth our focus. The aim of this study is to compare the outcomes of LSG with versus without Seamguard buttressing of the staple line during LSG.

Behavior of R.C. beams with lap-spliced hybrid bars under flexure

ABSTRACT The steel fiber-reinforced polymer composite bars Known as (SFCB) are new kind of reinforcement, for concrete structures. A layer of glass fibers and reinforced polymer surrounding the steel bars resulting in the (GFRP), when used as concrete reinforcement contributes for enough, serviceability strength, and durability. Increasing the elastic modulus of GFRP bar, which have function of protecting corrosion in addition to reduce the initial cost of the FRP bar, is the purpose of hybridization. SFCB has the advantages of being noncorrosive, nonmagnetic nonconductive, and light in weight, along with high strength. This study presents the behavioral characteristics of RC beams, with tensile lap-spliced steel fibers—coated bars under flexure. Ten beam specimens were tested, with concrete cross-section of (25*40*420) cm and compressive strength of 30 MPa. One beam specimen, (R) was taken as reference as it was reinforced with no lap splice. Nine beam specimens were divided into three groups. Group (A) contained three beam specimens reinforced with SFCB of diameter 16 mm and lap splice of 50φ, one with stirrups, without stirrups and with staggered lap splice. Group(B) contains three beams reinforced with SFCB of 16 mm diameter and lap splice of 55 φ one with stirrups, without stirrups and with staggered lap splice. Group(C) contains three beam specimens reinforced with SFCB of 16 mm diameter and lap splice of 60 φ one with stirrups, without stirrups and with staggered lap splice. Beams were exposed to pure flexure. Crack patterns and results are presented along with stress-strain curves. Finally, conclusions are summarized and presented.

Regarding their feeling, they said that reinforcement from the teacher makes them feel appreciated, motivated and happy during the teaching-learning process, which means that the role of reinforcement is very important.

Mechanical properties, degradation behavior and cytocompatibility of biodegradable 3vol%X (X = MgO, ZnO and CuO)/Zn matrix composites with excellent dispersion property fabricated by graphene oxide-assisted hetero-aggregation

Metal matrix composites have been recognized as a feasible approach to obtain a new generation of biodegradable Zn-based material. Nevertheless, there is a great challenge in achieving good dispersion properties of the bioactive reinforcements within zinc matrix. A novel and facile approach, namely graphene oxide (GO)-assisted hetero-aggregation, were developed to achieve uniformly dispersed nanoceramics in the Zn matrix, by using very low-content (0.03 vol%) GO as a linker between the Zn matrix and reinforcement. The negatively-charged GO becomes a suitable “bridge” connected the positively-charged metallic powder and bioactive reinforcement by charge neutralization in polarity solvent. Three kinds of reinforcements, including MgO, ZnO and CuO, were used to verify the feasibility of the above-mentioned method. As-sintered 3CuO/Zn matrix composites, which possessed uniformly distributed reinforcement, uniaxial compressive strength of 301.2 MPa, failure strain over 40%, moderate corrosion rate of 0.063 mm·y−1, acceptable cytocompatibility and antibacterial property, should be a useful material for orthopedic applications.

In‐plane shear behaviors of unbalanced 3D interlock woven reinforcement in bias extension test: Experiments and finite element modeling

AbstractIn this paper, the in‐plane shear deformation of unbalanced 3D interlock woven reinforcement (IWR) was investigated through experiments and finite element modeling. Five specimens with five layers warp (six layers weft) were designed and prepared. The warp is 792 tex carbon tows and weft is 396 tex carbon tows. This kind of reinforcement is unbalanced because that the linear density of warp is different from that of weft. The in‐plane shear deformation of unbalanced 3D IWR was tested by bias extension test. The bias extension process was simulated by finite element method from macro and meso scales. The results of simulation are basically consistent with experiments. The bias extension process can be divided into three stages: Meso scale deformation stage, multiscale deformation stage and Reinforcement failure stage. At meso scale deformation stage, the tensile load and shear angle are small when the displacement is less than 7.5 mm. There is no obvious change in the macro scale, while the weft slipping in the meso scale mainly occurs in area B. The deformation of B1 and B2 are asymmetric because the linear density of warp is different from that of weft. In the multiscale deformation stage, asymmetric deformation at the macro scale begins to appear when the displacement is between 7.5 mm and 20 mm. There is obvious in‐plane shear deformation in area C at the meso scale. In the reinforcement failure stage, A large number of weft yarns are pulled out from the reinforcement in area B.

Simulation of Geocell-Reinforced Foundation Using Particle Flow Code

Interlock-enhanced integral geocells are three-dimensional (3D) cellular structures. They are widely used in foundations to increase the load-bearing capacity and reduce the foundation settlement. However, as a new kind of reinforcement, some key considerations, such as the interface between the soil and the interlock-enhanced integral geocells and the failure mode, and mechanics of the interlock-enhanced integral-geocell-reinforced soil foundations, are not clarified yet. In this study, we investigated geocell-reinforced foundation using particle flow code (PFC3D) based on the discrete element method. The initial states and loading processes were simulated according to the finished model texts. The stress distribution, particle displacements, and contact forces were examined to determine the contribution of the interlock-enhanced integral geocells to the reinforced foundations. The interface between particles and the interlock-enhanced integral geocells, the failure mode, and the reinforcement mechanism of the interlock-enhanced integral-geocell-reinforced foundations are discussed. The numerical simulation results reveal that the characteristics of the interlock-enhanced integral-geocell-reinforced foundation can be well simulated by PFC3D. Soil particles are not displaced under the applied load because of the sidewalls of the interlock-enhanced integral geocells. The interlock-enhanced integral geocells allow soil particles penetrate from one side of the cell to the other owing that geocells have a 3D network structure with aperture geometry. Therefore, lateral deformation or potential strain in the soil is restrained. The interlock-enhanced integral geocell distributes the applied load over a wider area, thus increasing the shear strength of the composite system. The load-bearing capacity of the soil foundation is improved by the interlock-enhanced integral geocell.

Energy Distribution in Dowel-Type Joints in Timber Structures When Using Expansive Kits

This paper provides a study of the mechanical energy distribution in dowel-type joints in timber structures when using expansive kits. The compression caused by the expansive kit increases the friction between the dowel and the timber’s hole, opposing the longitudinal sliding that occurs during the bending of the dowel. The ensuing rope effect increases the load capacity of the joint. The aim was to determine the advantages and disadvantages of using this kind of reinforcement. For this purpose, an ad hoc finite element model of the joint was prepared taking the contact between the different components of the joint into account and appropriately simulating the radial expansion of the dowel and the behavior of the timber. The model was checked for accuracy by comparing the results with those coming from a set of experimental tests. After that, the model was used to verify that the use of the expansive kit reinforcement leads to a slight improvement in the load capacity of the joint. This improvement is related to the frictional forces, whose effect is especially significant at low levels of joint displacement.

Compressive behavior of RC members with rectangular continuous transverse reinforcement

AbstractRectangular Continuous Transverse Reinforcement (RCTR), as a replacement for conventional ties, is a relatively new form of reinforcement that can accelerate and facilitate the construction of reinforcement for RC members. In this study, the compressive behavior of concrete members with this kind of reinforcement is experimentally and theoretically investigated. Twenty‐eight RC short column specimens with multiple arrangements for bar size and spacing of transverse reinforcement; including RCTR and conventional ties are examined under monotonic and half‐cyclic loadings. The results imply that RCTR is a valid substitute for traditional ties and to a certain extent can improve the compressive strength of RC members. Based on Elasto‐Plastic and Fracture (EPF) concrete model, a theoretical method is proposed in order to predict the behavior of such members, which conforms well with the experimental results. Furthermore, the validity of existing design provisions in the compressive design of these members is investigated.

Tribolayer Behaviour and Wear of Artificially Aged Al6061 Hybrid Composites

The current work focuses on enhancing wear resistance due to the presence of reinforcements and the effect of ageing treatment on hybrid composites of Al6061-SiC+B4C. By varying weight percentage, two kinds of reinforcements, viz. silicon carbide and boron carbide, were prepared for hybrid composites by the liquid state process known as the method of stir casting. The solutionising temperature of 550 °C for 2 hours and ageing temperature of 100-200°C at different time intervals were used for both Al6061 alloy and its composites during heat treatment. Microstructural and mechanical characterisation were carried out using a standard testing procedure. Compared to Al6061 matrix alloy, artificially peak aged composites show 100-140% improvement in hardness due to harder reinforcements and precipitation of solute rich secondary phases during ageing treatment. Overall, an 80-100% increase in wear resistance observed during peak ageing of hybrid composites. Analysis of Al6061 matrix alloy wear out surface shows extensive grooving and ploughing of the surface with the matrix material smear at many spots. The presence of tribolayer in Al6061-SiC+B4C composites shows a smoother surface than the Al6061 matrix alloy, which results in an excellent lubrication effect during an improvement in wear resistance. The wear surface of base aluminium alloy doesn’t show the existence of iron in the tribolayer. The research work is significant in forming a thermally activated wear-resistant metallic tribolayer with good tribological properties.

Poly(methyl methacrylate) bone cement, its rise, growth, downfall and future

AbstractPoly(methyl methacrylate) (PMMA)‐based bone cements (BCs) can be defined as a family of materials that consist of powder and liquid phases which after mixing form a plastic paste that can self‐set once implanted in the human body. PMMA‐based BCs are easily molded and adapted to complex bone cavities or used in orthodontic applications to restore dental damage. The main advantages of the use of cement are the excellent primary fixation between bone and implant and, therefore, the faster recovery of the patient. Despite the initial success rate of implant fixation with BCs, they have some disadvantages such as local tissue damage due to exothermic polymerization reactions, mechanical mismatch between native bone and cement, lack of bone regeneration and bioactivity and poor mechanical properties which may cause the failure of the BCs. BCs are still considered as a top option for bone repair. Due to the disadvantages highlighted, research has focused on alternative materials used with PMMA‐based BCs. This review aims to critically review the BCs and emerging materials used in combination with PMMA‐based BCs. These materials include titania, apatite–wollastonite (A‐W), glass ceramic (GC) and hydroxyapatite (HA). The review discusses the properties of these materials and their pathway to clinical study. Among the various kinds of reinforcement, HA has been extensively used. So, in this review, we compare the effects of HA as reinforcement in PMMA‐based BCs. Upcoming study of PMMA‐based BCs should concentrate on trialing combinations of these reinforcing agents as this might improve beneficial characteristics. © 2020 Society of Industrial Chemistry

Composite brazing of C/C composite and Ni-based superalloy using (Ag-10Ti)+TiC filler material

With the aim of alleviating the residual thermal stress in the C/C-GH3044 joints, a novel composite brazing, which combines Ag-Ti reactive composite brazing and TiC particle-reinforced composite brazing, was adopted for joining C/C composite to Ni-based superalloy GH3044 using (Ag-10Ti)+TiC composite filler material. The results showed that the composite interlayer was strengthened by four kinds of reinforcements, containing the introduced TiC, the in situ synthesized AgTi and Ti 2 Ni phases, and the residual Ti particles. With increasing TiC content from 0 to 32 %, the thermal expansion coefficient of the composite interlayer declined by 18.2 %, which is helpful in alleviating the residual thermal stress in the joints. In addition, the introduced TiC particles decreased the fluidity of the filler material and inhibited the inter-diffusion of atoms between GH3044 and filler material. As a result, the continuous brittle compound Ti 2 Ni in the composite interlayer was effectively reduced, so the composite interlayer had good plasticity. Meanwhile, the thickness of the composite interlayer gradually increased from 260 μm to 520 μm, and the finite element analysis showed that the corresponding peak value of von Mises stress decreasedby 20.1 %. The highest shear strength of the joints was 67.2 MPa obtained with (Ag-10Ti)+24 %TiC at 1020°C for 30 min,which is almost the same strength as the C/C composite matrix used in this study.

Fracture of magnesium matrix nanocomposites - A review

As one of the lightest metallic materials, magnesium is considered as a promising replacement for aluminum, titanium, and steel. However, lightweight energy-saving magnesium and magnesium alloys suffer from poor ductility (5%–8%) due to their hexagonal closed packed crystalline structure and a limited number of easily activated independent slip systems at room temperature. This creates some challenges for magnesium and its alloys for various industrial applications. One technique to improve both strength and ductility, without any tangible weight penalty, of magnesium and its alloys is to add nanosize (less than 100 nm) reinforcements (e.g. nanoparticles) to the matrix as creat so-called magnesium nanocomposites. Various nano-reinforcing materials including oxides (Al2O3, TiO2, Y2O3, ZnO, ZrO2), carbides (SiC, B4C, TiC), nitrides (BN, AlN, TiN), borides (TiB2, SiB6, ZrB2), and carbonaceous materials (carbon nanotube and carbon nanoplatelets). The volume fraction of these nano-size reinforcing structures are normally less than 3 vol% to avoid the clustering (agglomeration) of the nano-reinforcements which can adversely affect strength and ductility. That is, depending on the matrix (magnesium and magnesium alloys) and the nanosize reinforcement, there is an optimum volume fraction beyond which the properties (strength and ductility) would decrease. Though various aspects of the microstructure/mechanical property/manufacturing process of the magnesium nanocomposites have been studied so far, the failure and, in particular, fracture of these materials have not been yet classified properly. Investigating the fracture of magnesium nanocomposites, including the type of fracture, fracture mechanism, the effect of the nano-reinforcements on the fracture of Mg nanocomposites, enables the researchers to assess the role of nanosized reinforcement on the modes of failure and mechanical properties. This paper aims at providing a review of the fractography of compressive and tensile tests of nanocomposites Mg, classifying fractography by all kinds of reinforcement and working conditions of the Mg nanocomposite. Also, the effect of test temperature, cyclic loading, and heat treatment on the fracture of magnesium -matrix nanocomposite is discussed thoroughly. Among various nanoparticles and according to the review of the available literature, Al, Y2O3, and NiTi can significantly improve the tensile strength of the Mg matrix while ZnO and Sm2O3 reinforced nanocomposites show higher compressive yield stress.

The Effectiveness of Reinforcement and Processing on Mechanical Properties, Wear Behavior and Damping Response of Aluminum Matrix Composites

Abstract Metal matrix composites are an essential product used in engineering materials. This product has wide applications in automotive, aerospace, and other uses because of their lower density, good specific strength, best machinability, and better mechanical properties compared to Al 6063 alloy. In this paper, four different reinforced such as (MA), (MCA), (NFC) and (SA) with a constant rate of 5 wt.% for each reinforced element used and mixed with Al 6063 alloy as a metal matrix composite by using modified two-step mechanical stirrer and having three blades at each step. Coated carbide tool insert was carrying out the turning process. Surface roughness measured after turning of every change in cutting speed. Average chip length and its shape style formation performed within cutting speeds of 10 and 90 m/min, which appears in different length and shapes. Mechanical properties, damping characteristics, and wear loss improved dramatically by adding all reinforced composites to the base Al 6063 alloys. As the results of experiments, the surface roughness decreased by adding all four types of reinforcements. The mechanical properties, wear loss and damping characteristics improved by the constituents of all kinds of reinforcements and also by mixing of all types of constituents together. The effects of MA and NFC are more compared to MCA and SA for improving all conditions of experimental results. Microstructure observation produces compact grain boundaries with strong grains of metal matrix composites compared to Al 6063 alloys.

Multi-walled Carbon Nanotubes Reinforced-Based Magnesium Metal Matrix Composites Prepared by Powder Metallurgy

Nanostructured carbons, for example, carbon nanotubes (CNTs) arise much attraction in the last decades because of its remarkable physical and mechanical properties. The unique physical, chemical and mechanical properties of CNTs make them attractive for biomedical applications. CNTs have been used to modify conventional biomedical materials to enhance mechanical properties, biocompatibility, or to impart other functionalities. One of the metal materials which attract high attention in the biomedical field for orthopaedics application is Magnesium. Recently, many researchers are studying the magnesium reinforced with a different kind of reinforcement. As a lightest metal structure material, magnesium matrix composites show many advantages over monolithic magnesium and magnesium alloys. In this study, Magnesium metal matrix was reinforced by multi-walled carbon nanotubes (MWCNTs) in order to observe the physical and the mechanical properties of the composites. The MWCNTs-Reinforced based magnesium MMC was performed using powder metallurgy process with MWCNTs loading are: 0, 0.1, 0.2, 0.3 and 0.5 %. The temperature of the sintering process was conducted at 600°C by flowing argon gas during the process with the holding time of 2 hours. The experiment result exhibited that the porosity of MMC was increased with the reinforcement by the increasing of the loading MWCNTs observed by metallography and SEM. The mechanical properties showed that the loading of MWCNTs 0.1 % increased the micro-hardness of MMC about 19% compared to pure magnesium, with the peaks at the loading of MWCNTs 0.3 % which increased the mechanical properties about 0.31% at highest hardness value of 46.5 HV.
