Fabrication of Embedded Glass and Tissue Fiber Hybrid Composites and Analysis of Mechanical Properties at Different Conditions

Abstract

Now a days the use of polymer composites is expanding unexpectedly due to their characteristics to replace the composite materials having lower density, low thermal stability etc. The polymer matrix composites are used in structural applications because they show some properties like stiffness, less weight than alternative materials etc. Various layers of laminated composites exhibit the particular property of composite material having a particular function to perform. Fiber-reinforced plastics (FRP) have been generally acknowledged as a versatile material for structural and nonstructural applications. The primary reason for interest in FRP for underlying applications is because of its high specific modulus and the strength of reinforcing materials. The fiber-reinforced composite materials have attained significant development in the last few decades because of their desirable properties, for example, light weight, high strength-to-weight ratio, and comparatively easy process ability. Glass fibers are most commonly used as reinforcement, followed by carbon and boron fibers. Continuous glass fiber reinforced thermoplastic composites (GFRTP) have been introduced, as structural materials for high performance aerospace and other industrial applications, due to their high strain to failure, high specific strength and specific stiffness, better impact tolerance, short processing cycle time, infinite shelf life of prepreg, and recyclability. Recently, there is an increasing interest in the application of thermoplastic resins as base materials rather than the thermosetting matrix. As such, the utilization of polypropylene grafted maleic anhydride (PP-g-MAH) as an interfacial coupler is thoroughly suggested and has been incomprehensibly described in the written works. In the beginning without modifier polymer will have less use because of their thermal disintegration and low shear stress which can be upgraded by adding useful fillers with the base material. In this research work, the composite materials were produced by hand layer method based on the glass fiber and tissue fiber of glass with mix of resin and nanoparticles. Polyester resin was used 150g and hardener was used 10% of resin, similarly epoxy resin was used 115g and hardener used 10% of resin. Different composites were fabricated by varying quantity of nanoparticles such as 0g, 3g, 6g, 9g of nanoparticles were used and investigate their mechanical properties such as tensile strength, elongation, yield point, impact load by the universal testing machine and impact testing machine respectively. Variation of mechanical properties of these composites was compared between before radiation and after radiation. It is found that the composite with polyester resin is better than the composite with epoxy resin and the tensile strength is increased after radiation.
