Experimental study of the mechanical and optical properties of glass-polyester fiber composite based on response surface methodology

Due to the intricate amalgamation of various components, composite materials boast mechanical properties that surpass those of their constituents. Among these composite materials, glass fiber-reinforced polyester composites emerge as prominent contenders, finding extensive utility, especially in agricultural greenhouse construction. These structures garner significant acclaim for their exceptional ability to withstand adverse weather conditions, ensure prolonged durability, and transmit light efficiently, thus creating optimal growing conditions. Consequently, they have become the favored choice among farmers seeking dependable and sustainable environments for cultivation. Within the scope of this study, we employ Response Surface Methodology (RSM) as a comprehensive tool to delve deeply into the mechanical and optical characteristics inherent in such composite materials. Our investigation is meticulously tailored to unravel the intricate interplay among crucial factors such as fiber content, length, and plate thickness, elucidating their direct impacts on mechanical properties like stress and elasticity modulus. Our rigorous examination reveals that the pinnacle of mechanical performance is attained within a specific range: fiber content ranging from 20% to 40%, fiber lengths spanning 35 to 45 mm, and plate thicknesses measuring between 0.6 to 3 mm. Furthermore, our meticulous analysis of transmittance measurements uncovers an intriguing correlation: thinner thicknesses and lower fiber content correspond with heightened light transmission across the visible spectrum. Conversely, elevating the fiber content or thickness enhances mechanical robustness but concurrently diminishes light transmittance. Thus, achieving a harmonious equilibrium among these attributes becomes imperative for the pragmatic construction of agricultural greenhouses. Additionally, we venture into incorporating ultraviolet (UV) plastic films to augment the optical prowess of these composites, further elevating their efficacy in greenhouse applications. By embarking on this comprehensive investigation, our overarching objective is to propel sustainable farming practices forward by furnishing a nuanced understanding of the multifaceted factors that shape the performance of glass fiber-polyester composites in agricultural greenhouse applications.

Wear behaviour of glass fiber reinforced polyester composites under dry friction and fluid film lubrication

Abstract The use of composite materials, which are more economical and have better material properties, has become widespread in the industry lately. The glass fiber reinforced polyester composite materials constitute majority of composite materials produced in industry. Wear reduces working life of machine parts, affects their functions, and causes undesired deterioration, resulting in part separation over the contact surface. The machine parts produced from glass fiber reinforced polyester composite materials wear out because of exposure to dry friction and fluid film lubrication under different operating conditions. In this study, wear behaviours of glass fiber reinforced polyester composite materials under dry friction and fluid film lubrication conditions were investigated. The various results were obtained with this study. The wear resistances of samples in dry friction and fluid film lubrication conditions are like each other. The use of glass fiber, glass bead and plasticizer tensile additive in glass fiber reinforced polyester composite specimens is effective in improving the wear resistance of specimens.

Investigation of the Effects of Environmental Conditions on Wear Behaviors in Glass Fiber Reinforced Polyester Composite Materials Containing Different Types of Polyester and Low Profile Additive

Kompozit malzemeler, gelişen teknoloji ile birlikte günümüzde birçok alanda başarıyla kullanılmaktadırlar. Elyaf takviyeli polimer kompozitler, yüksek dayanım ve düşük maliyet özelliklerinden dolayı en sık tercih edilen kompozit malzemelerdir. Cam elyaf takviyeli polyester (CTP) kompozitler kullanım alanlarına göre istenilen mekanik ve tribolojik özellikleri karşılayan polimer matrisli ve cam elyaf takviye malzemeli bir kompozit türüdür. Cam elyaf takviyeli polyester kompozit malzemeler farklı türlerde polyester ve çekme katkıları içerebilmektedir.

Investigation on impact properties of basalt and glass fiber reinforced polyester composites filled with nano silica

The relevance of granite waste is growing alongside the global demand for granite. This waste comprises various forms, including large granite pieces, tiny fragments, dust, and other debris. This research aimed to create a novel composite by incorporating nano silica from granite powder as a filler, combining it with basalt and glass fibres as the matrix, and using polyester as the resin. The fabrication involved Fiber Reinforced Composite (FRP) production through hand lay-up and vacuum silicon moulding to eliminate trapped air during lamination. After fabrication, tests were conducted for hardness, density, and Low-Velocity Impact under dropping weight. The results indicated that introducing nano silica as a filler in polyester resin positively impacted Basalt Fiber Reinforced Polyester Composite (BFRPC) and Glass Fiber Reinforced Polyester Composite (GFRPC). Analysis showed that as the nano-silica content increased, so did energy absorbed, impact strength and ductility index, up to a 1wt% nano-silica concentration. Beyond this point, agglomeration occurred, causing a decrease in these values. The 1 Nano silica Basalt Fiber Reinforced Polyester Composite (1NSBFRPC) material exhibited the highest energy absorption at 103.21J, indicating strong impact strength at 21.27kJ/m2. Conversely, the 1NSGFRPC material demonstrated the highest ductility index at 4.13. In comparison, Carbon Tech Global's (CTG) energy absorption, initially 25.56J, experienced a significant increase of 303.79%, reaching 103.21J. The impact strength also showed a notable shift, escalating by 396.96% from 4.28 KJ/m2 to an impressive 21.27kJ/m2. This shift in impact strength represented a remarkable 128.2% surge, highlighting the significant influence of integrating nano-silica. This new composite suits truck body carriers and offers environmental benefits. Furthermore, utilising nano silica in this context not only aids in waste reduction within the granite sector but also contributes to sustainable resources.

Experimental and numerical evaluation of mechanical performances of hybrid Palmyra-Palm-Leaf-Stalk/Glass fiber reinforced polyester composites

In the present work, four layered Palmyra-Palm-Leaf-Stalk (PPLSF)/Glass hybrid composites laminates with six distinct stacking orders were made by following hand lay-up method. Different experiments were carried out to determine the tensile, flexural, impact and hardness of the laminates as per ASTM standard. The results reveal that the addition of glass fiber to PPLSF significantly enhanced the mechanical performance of the laminates. On successive replacement of PPLSF by glass fiber, an enhancement of properties such as 291.39% for tensile strength, 72.08% for flexural strength, 75.82% for impact strength, and 78.44% for micro-hardness was observed. Again, it is also noticed that the stacking order plays an important role in influencing the properties while comparing experimental finding of laminates with equal weight percentages PPLSF and glass fiber. Further to perform Finite Element Analysis (FEA), a 3D CAD model of tensile and flexural specimen was created in space-claim modeler of ANSYS R19.0 and subsequently imported to generate numerical predicted values. While comparing the numerical and experimental results, there was very good agreement among the results was found. Scanning Electron Microscope (SEM) was used for fractography analysis of the tested samples to examine the different mode of failures.

Identification of regularities in the behavior of a glass fiber-reinforced polyester composite of the impact test based on ASTM D256 standard

In this research, commotional analysis based on the finite element analysis (FEA) has been performed to investigate IZOD impact test based on the ASTM D256 standard. The ANSYS model primarily employs a composite constructed of glass fiber-reinforced polyester for the boundary conditions. The CEAST 9050 instrument was used to implement the impacting technique in the experimental inquiry. By employing mathematics, we have calculated that the applied force is 9.2 N. A hammer traveling at a speed of 3.5 meters per second is used to strike the samples, and the results are recorded after each blow. The object of this study is the mechanical properties and structural integrity of the composite material composed of glass fibers and polyester when subjected to impact forces. The main hypothesis of the study encompasses the optimism that the glass fiber-reinforced polyester composite, when put through the Izod impact test in accordance with ASTM D256. Convergence between the overall deformation indicator and the numerical result has occurred. Results from the numerical analysis were examined and confirmed, and compared to those from the experiment. The specimens in this study were totally distorted at three different thicknesses (6 mm, 8 mm, and 10 mm). Deformation was found to be greatest for the thinnest value of thickness considered in the study (6 millimeters), as determined by the results of the computer analysis. This was the case even though the thickness value was not the sole criterion. This is the actual state of affairs. The specimen was subjected to a von-Mises stress at three different thicknesses of 6 mm, 8 mm, and 10 mm. The computer investigation revealed that the Von-Mises stress was highest at the thinnest possible thickness of just 6 millimeters. Internal energy, kinetic energy, and touch energy are only few of the various types of energy that have been studied in the context of energy conservation

Advanced Ultrasonic Inspection of Thick-Section Composite Structures for In-Field Asset Maintenance.

An investigation into the inspection capabilities of in-field advanced ultrasound detection for use on ultra-thick (20 to 100 mm) glass fibre-reinforced polyester composites is presented. Plates were manufactured using custom moulding techniques, such that delamination flaws were created at calibrated depths. The full matrix capture technique with an on-board total focussing method was used to detect flaws scanned by a 0.5 MHz linear array probe. Flaw through-thickness dimensions were altered to assess the threshold for crack face separation at which delaminations could be identified. Furthermore, part thickness and in-plane flaw dimensions were varied to identify the inspection capability limitations of advanced ultrasonics for thick composites. The results presented in this study demonstrate an inverse relationship between the ability to find delaminations and plate thicknesses, with inspections successful at depths up to 74 mm. When the delamination thickness exhibited surface-to-surface contact, the inspection capability was reduced to 35 mm. There was an exponential decay relationship between the accuracy of the flaw depth measurement and plate thickness, likely due to the necessity of low probe frequencies. The effective inspection depth was determined to be in the range of 1 to 20 times the wavelength. It is speculated that the accuracy of measurements could be improved using probes with novel coupling solutions, and detectors with optimised signal processing/filtration algorithms.

Effect of combined natural and synthetic filler addition on the behaviour of glass fibre reinforced composite

ABSTRACT This study was focused on developing and evaluating the impacts of wood and graphite fillers on an E-glass fibre-reinforced polyester composite. The fillers employed in this study include teak, casuarina, psuedon wood dust, graphite, and hybrid fillers such as casuarina and graphite fillers. They tested for tension, flexural, impact, hardness, and dynamic mechanical analysis. In the current work, the optimum loading level is 15 wt% which was determined through testing at various loading levels. The experimental results have shown that the mechanical, physical, and thermomechanical properties of glass fiber reinforced polyester composites improvement mechanism analysis depend upon chemically treated wood dust fillers by avoiding surface delamination during fabrication. By using the hand layup method, composites were created by maintaining the fibre constant while distributing the fillers following the rule of mixture; a hybrid composite has a filler distribution of 1:1. Hybrid composite has exhibited increased flexural strength and hardness by 72.77%, 63.33% compared to casuarina wood of 15 wt% by avoiding incompatibility of casuarina wood filler with the resin. The glass transition value of the hybrid composite was increased by 1.4% compared to the above said casuarina wood composite, making it a more thermally resistant material. The hardness of the hybrid composite has increased by 2.78% compared to the teak wood of 15 wt% composite.

State-of-the-art ensemble learning and unsupervised learning in fatigue crack recognition of glass fiber reinforced polyester composite (GFRP) using acoustic emission

Fatigue strength is one of the most important properties of composite materials because it directly relates to their lifespan. Acoustic emission (AE) is a passive structural health monitoring (SHM) technique that provides real-time damage detection based on stress waves generated by cracks in the structure. This study evaluates the damage progression on glass fiber reinforced polyester composite specimens using different approaches of machine learning. Different methodologies for damage detection and characterization of AE parameters are presented. Three different ensemble learning methods namely, XGboost, LightGBM, and CatBoost were chosen to predict damages and AE parameters. SHAP values were used to select AE key features and K-means algorithms were employed to classify damage severity. The accuracy of these approaches demonstrates the reliability of various machine learning techniques in predicting the fatigue life of composite materials using acoustic emission.

The usage of laminated glass fiber reinforced polyester composites in aerospace applications helps to reduce overall weight of the aerospace structures. The flexural strength of the laminated glass fiber reinforced composites becomes more important when they are employing for aeroplane wings. In this work, a laminated glass fiber polyester composite with two distinct sets of six different woven lamina stacking sequences is manufactured via hand layup technique. The effect of stacking sequence over the total ply failure load are investigated through universal testing machine. Finally, the progressive failure of the lamina in composites is also examined using ANSYS software.

A study of surface roughness and material removal rate for optimal parametric combination in turning of GFRP composites

High surface quality and/or dimensional accuracy of the products produced by machining plays an important role in the part performance. The use of polymer materials is gradually replacing that of metallic materials. Due to their anisotropy and non-homogeneity, their machining behavior differs greatly from that of normal metallic materials. Because the phenomena responsible for material removal while cutting fiber reinforced plastic composite materials and those of typical metals and their alloys differ fundamentally, particular attention must be paid to the choice of the proper tool and machining conditions. The present study examines various turning process parameters, including cutting speed, feed rate, depth of cut, and their significance in determining the surface roughness and material removal rate of glass fiber reinforced polyester (GFRP) tubes. The experimental work is carried out on a CNC lathe. After turning the external diameter of the workpiece according to predetermined turning conditions, average surface roughness (Ra) was measured, and material removal rate (MRR) was calculated. The study utilizes the methodology of Grey Relational Analysis (GRA) and Analysis of Variance (ANOVA) to determine the optimal parametric combination giving the smallest values of Ra and the highest values of MRR.

Mechanical Properties and Water Absorption of Glass Fiber Reinforced Composite Laminates made by Varying Stacking Sequence

This study aims to demonstrate the effects of various stacking sequences of different glass fiber architecture forms on the mechanical properties of glass fibre reinforced polyester composites. The composites were manufactured by hand lay-up technique and its mechanical properties were characterized in terms of tensile, flexural, and drop-ball impact tests as well as water absorption. The mechanical properties of the glass fiber reinforced polyester were somewhat affected depending on the stacking sequences from single alternating order, double alternating order, and triple alternating order of chopped strand mat and plain-woven fabric piled in ten (10) to fourteen (14) layers. The laminates consisting of alternating sequence manner of plain-woven fabric and chopped strand mat stacked in different layers have no significant effect on the mechanical properties. Stacking sequence of double alternating layer piled in twelve (12) layers was found to have better tensile strength than single and double alternating order of two different glass fiber form while the triple alternating manner piled in twelve (12) layers resulted to higher tensile modulus. The double alternating order of different glass fiber forms stacked in twelve (12) layers resulted to an improvement in flexural properties. Some selected laminates exhibited no delamination in drop-ball impact test and minimal water absorption when immersed in water for 30 days for all the laminates.

Influence of Stress Level and Fibre Volume Fraction on Fatigue Performance of Glass Fibre-Reinforced Polyester Composites.

Fibre-reinforced polymeric composite materials are becoming substantial and convenient materials in the repair and replacement of traditional metallic materials due to their high stiffness. The composites undergo different types of fatigue loads during their service life. The drive to enhance the design methodologies and predictive models of fibre-reinforced polymeric composite materials subjected to fatigue stresses is reliant on more precise and reliable techniques for assessing their fatigue life. The influences of fibre volume fraction and stress level on the fatigue performance of glass fibre-reinforced polyester (GFRP) composite materials have been studied in the tension–tension fatigue scenario. The fibre volume fractions for this investigation were set to: 20%, 35%, and 50%. The tensile testing of specimens was performed using a universal testing machine and the Young’s modulus was validated with four different prediction models. In order to identify the modes of failure as well as the fatigue life of composites, polyester-based GFRP specimens were evaluated at five stress levels which were 75%, 65%, 50%, 40%, and 25% of the maximum tensile stress until either a fracture occurred or five million fatigue cycles was reached. The experimental results showed that glass fibre-reinforced polyester samples had a pure tension failure at high applied stress levels, while at low stress levels the failure mode was governed by stress levels. Finally, the experimental results of GFRP composite samples with different volume fractions were utilized for model validation and comparison, which showed that the proposed framework yields acceptable correlations of predicted fatigue lives in tension–tension fatigue regimes with experimental ones.

Study on Machining Parameters and Mechanical Properties of Hybrid Agave Sisalana and Glass Fiber-reinforced Polyester Composites (A/GFRP)

ABSTRACT Agave fiber/polymer matrix composites have recently been used in automotive, aerospace, and construction field, where they will be secure for shape-made applications. Hand lay-up is used to make Agave and Glass fiber-reinforced polyester composites (A/GFRP), Agave fiber-reinforced polyester composites (AFRP), and Glass fiber-reinforced polyester composites (GFRP). The impact energy absorbed and tensile strength for A/GFRP material are higher than those for AFRP material. Drilling of GFRP, AFRP, and A/GFRP composites is carried out by using carbide twist drill D 5407060 of 6 mm diameter. Process parameters include two distinct speeds (800 rpm and 1200 rpm) and two distinct feeds (0.02 mm/rev and 0.04 mm/rev). The influences of processing parameters on thrust force and delamination while drilling GFRP, AFRP, and A/GFRP materials are investigated. For the optimum process parameter (feed = 0.02 mm/rev and 800 rpm) for GFRP, AFRP, and A/GFRP, the thrust force and delamination factor are limited at these feed rate conditions. In comparison to AFRP, delamination is minimum for A/GFRP drilled with carbide tools at lower feed rates as per microstructural examination. The Taguchi technique is used to determine the best feed and speed parameters for machining responses, and it demonstrates that acceptable values are achievable with A/GFRP.

Experimental Investigation on Mechanical Properties of A/GFRP, B/GFRP and AB/GFRP Polymer Composites

This study aims to reveal the consequence of thickness reinforcement on Fiber Laminates (Polyester Resin, Glass Fiber, Aluminum, and Bentonite) and to see if it can enhance the mechanical properties and resistance of laminates. Glass fiber reinforced polymer composites have recently been used in automotive, aerospace, and structural applications where they will be safe for the application s unique shape. Hand layup was used to fabricate three different combinations, including Aluminium /Glass fiber reinforced polyester composites (A/GFRP), Bentonite/Glass fiber reinforced polyester composites (B/GFRP), and Aluminium&Bentonie/Glass fiber reinforced polyester composites (AB/GFRP). Results revealed that AB/GFRP had better tensile strength, flexural strength, and hardness than GFRP and A/GFRP. Under normal atmospheric conditions and after exposure to boiling water, hybrid Aluminium&Bentonite and glass fiber-reinforced nanocomposites have improved mechanical properties than other hybrid composites. After exposure to temperature, the flexural strength, tensile strength and stiffness of AB/GFRP Composites are 40 % higher than A/GFRP and 17.44% higher than B/GFRP Composites.

Epoxy and Polyester Composites' Characteristics under Tribological Loading Conditions.

This research examines the friction and dry wear behaviours of glass fibre-reinforced epoxy (GFRE) and glass fibre-reinforced polyester (GFRP) composites. Three fibre orientations—parallel orientation (P–O), anti-parallel orientation (AP–O), and normal orientation (N–O)—and various sliding distances from 0–15 km were examined. The experiments were carried out using a block-on-ring configuration at room temperature, an applied load of 30 N, and a sliding velocity of 2.8 m/s. During the sliding, interface temperatures and frictional forces were captured and recorded. Worn surfaces were examined using scanning electron microscopy to identify the damage. The highest wear rates for GFRE composites occurred in those with AP–O fibres, while the highest wear rates for GFRP composites occurred in those with P–O fibres. At longer sliding distances, composites with P–O and N–O fibres had the lowest wear rates. The highest friction coefficient was observed for composites with N–O and P–O fibres at higher sliding speeds. The lowest friction coefficient value (0.25) was for composites with AP–O fibres. GFRP composites with P–O fibres had a higher wear rate than those with N–O fibres at the maximum speed.

Estimation of adhesive wear behavior of the glass fiber reinforced polyester composite materials using ANFIS model

Glass fiber reinforced polyester (GFRP) composite materials are widely used in various applications. The prediction of wear values for composite materials is very complex and nonlinear phenomena. Artificial intelligence methods (AI) and expert systems such as artificial neural networks (ANNs) and fuzzy inference systems (FIS) have a series of properties on modeling nonlinear systems. In some situations, ANNs are insufficient under abrupt changes in input variables. Adaptive Neuro Fuzzy Inference System (ANFIS) is capable of integrating the linguistic expressions of FIS with the adaptation and learning skills of the ANNs. The aim of this study is to determine the optimum material content and working conditions in terms of wear resistance. This study proposes an ANFIS sub-clustering based prediction model for estimation of wear behavior of GFRP composites within various concentrations of materials and under diverse loads and speeds. Proposed ANFIS model extracted optimum concentrations and operating parameters to obtain the minimum wear rate. Due to the wear rate estimation model, optimum wear rate value is reached to 25.0013 (mm3/Nm)*10−6 at CaCO3, polystyrene, glass fiber, glass bead, alumina, load and speed values of 49%, 0%, 11%, 10%, 0.8%, 10 N and 100 rpm respectively. A high estimation capability (R2 = 0.964) has been achieved using ANFIS Model.

Analysis of impacts of thermal shocks on mechanical properties of E-glass fiber reinforced polyester composites

Glass fiber reinforced polyester composites are economic and high-performance composite materialsthat has gained a wide range of applications. Besides the developments in composites design, scientific studies addressing the consequences of thermal changes on the mechanical properties of fiber reinforced polymer composites(FRPCs) are scarce. Therefore, the main aim of the present work is to investigate the physical/mechanical properties of glass fiber reinforced polyester composites under thermal shocks. The effects of thermal cycle duration (2, 5 and 20 hours) on the porosity and mechanical properties (maximum stress, strain, elastic modulus and impact resistance) of polymeric composites reinforced by glass fiber, woven fabric and copper/silica nanoparticles (NPs) were investigated. The results exhibited that the porosity and mechanical properties changed obviously in long duration cycles, i.e., 20 hours. Major reduction trends were observed when the fabric reinforced samples were further reinforced by NPs. It was concluded that although NPs reduce porosity and pose filling effect in composite matrix, can also provide stress concentration locations. The composites reinforced by woven fabric and prepared by RTM method provide better mechanical properties. Moreover, after thermal shocks, the fibers within the composite structure formed curved shapes. Consequently, a reduction occurred at the elastic modulus of fibrous reinforced composites (fiber or fabric) after thermal cycles. Besides theelevated porositywas the predominant factor reducing elastic modulus, fiber deformation was also considered as a hidden factor which has never been discussed in previous research studies. A model of bicomponent structure was used to explain the effects of fiber deformation on elastic modulus of the FRPCs.

Investigation of adhesive wear properties of glass fiber reinforced polyester composites having different chemical compositions

Glass fiber reinforced polyester composite materials are widely used in various areas due to their high specific strength, low weight, excellent elasticity, high corrosion resistance, and high thermal stability. This study aims to investigate the effects of resin materials and various fillers and wear parameters such as different loads and speeds on the tribological properties of glass fiber reinforced polyester composite materials. In this experimental study, various resins (tensile additive orthophthalic polyester and plain orthophthalic polyester), fillers (alumina and glass beads), and reinforcing materials were used during the sample preparation. The samples were subjected to an adhesive wear test at two different speeds ( n = 100 r/min and n = 200 r/min) and different loads ( F = 10 N and F = 20 N) at 150 m sliding distance. The friction coefficient and friction force were measured by the tribometer. The thickness of the wear trace was later measured and the wear rate was calculated. Wear surfaces of samples were visualized with a three-dimensional laser profilometer in order to obtain surface topographies and surface roughness values. The sample surfaces were examined by scanning electron microscopy in order to understand the wear mechanisms and to characterize the morphology of worn surfaces. Experimental results have shown that alumina or glass beads fillers can reduce the average friction coefficient when used in the correct amounts. The use of glass bead filler in orthophthalic polyester resin with tensile additive is more effective than reducing the wear rate compared to alumina filler. The load on the wear behavior of glass fiber reinforced polyester composite materials is more effective than the speed.
