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 non – reinforced 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.
