Effect of Temperature on Mechanical and Thermal Properties of Polyester Matrix Reinforced by Ordinary Glass Powder

The research focuses on the preparation composite material containing glass powder of grain size (10-15) reinforced polyester with volume fraction 30%. Many tests have been done in different temperature conditions including Bending test, Hardness, Impact and Thermal conductivity ( ).
The results show that Young's modulus ( ) decreases and fracture toughness ( ) for composites increase with increasing temperature, but Brinnels hardness decreases with increasing temperature. The result also shows that thermal conductivity ( ) increases with increasing temperature.
