Mechanical Properties for Unsaturated Polyester Reinforcement by Glass Fiber using Ultrasonic Technique

Abstract

In this study, the unsaturated polyester (UP) composite resin was used for binding the reinforcement such as glass fibers (GF) and polyvinylchloride (PVC) powder. Some mechanical properties of polymer composite have been investigated, by ultrasonic technique at 26 KHz, these properties are density, ultrasonic velocity, shear modulus, passion's ratio and elasticity modulus. Results show that all these properties were increase with increasing the concentration of GF% in the composite expect elasticity modulus and passion ratio decreasing. As passion's ratio is decrease until reaching 15%GF ratio where no further decrease occurs with increasing GF ratio.
