Viscoelasticity ˗ plastic behavior of fiber˗ reinforced polymer composites

Abstract

Fiber Reinforced Polymer (FRP) composites widely use in different fields such as, aerospace industries; automotive, water tank; marines; and building, etc. The current studies give a brief account of analysis of static and impact on glass fiber reinforcement composites comprising composite faces from glass fiber/polyester. Chopped strand mat E-glass layers were fabricated byusing hand lay-up process.Lamination was conducted at room temperature with 65% glass fibers and 35% polyester resin volume fraction. The target thickness of each laminate is 3mmlater; the composite panels were subjected to static and impact loading using Product Computerized Universal Testing Machine. The load-displacement and the load-time curves have been obtained to characterize the failure mechanisms in the glass fiber reinforcement composites. Fiberglass/polyester composites provide improvements in strength, stiffness and toughness. They also have corrosion resistance, compared with water tank made of high density polyethylene. Results were presented in different charts designed to help plastics engineers for an industrial manufacturing process of known material functions.
