Study of inter laminate layer effect on Impact and Hardness Properties for Unsaturated Polyester resin reinforced Hybrid Fabric composite

Abstract

In this research, we reported study of quality, sequential and directional layers for threetypes of fibers are woven perpendicular and random E- glass fiber and carbon choppedfiber effect on the impact and hardness shore (D) using as matrix unsaturated polyester.The composites were prepared by hand lay-up method. The composites constituentswere unsaturated polyester using a matrix with 25% volume fractions of Glass Fibers(G.F) as reinforcement and 5% carbon chopped fiber as hybrid fabric composite. Theresults showed that the non – reinforced unsaturated polyester have lower propertiesthan composites material tests are conducted on these specimens to determine the atmaximum load and hardness number using a universal testing machine and hardnessshore (D) testing machine. Different behavior was shown for the fiber/polyestercomposite depending on the type of the fiber. The sample which reinforced three layersfiberglass characterized the highest impact strength of these composites due to highchemical compatibility between reinforced materials (fiber and matrix) base resinpolyester.
