Determination of Some Mechanical Properties of Unsaturated Polyester Reinforced with Glass Fiber and Plam Fiber

Abstract

In this work a composite materials is prepared containing matrix of polymer (unsaturated polyester) reinforced with different reinforcing materials (glass fiber + plate fiber) in different values of volume fraction %. All samples for to mechanical tests were prepared by hand layup process. The mechanical tests can be classified into: bending, tensile strength, tensile strength at break, elongation at break and hardness. The study of mechanical test shows that the mechanical properties increase with the increase in volume fraction.
