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 three types of fibers are woven perpendicular and random E-glass fiber and carbon chopped fiber effect on the impact and hardness shore (D) using as matrix unsaturated polyester. The composites were prepared by hand lay-up method. The composites constituents were 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. The results showed that the nonreinforced unsaturated polyester have lower properties than composites material tests are conducted on these specimens to determine the at maximum load and hardness number using a universal testing machine and hardness shore (D) testing machine. Different behavior was shown for the fiber/polyester composite depending on the type of the fiber. The sample which reinforced three layers fiberglass characterized the highest impact strength of these composites due to high chemical compatibility between reinforced materials (fiber and matrix) base resin polyester.
