دراسة التأثير الحراري على الخواص الميكانيكية و الحرارية لمتراكب البولي أستر غير المشبع المدعم بمسحوق الزجاج الاعتيادي

الملخص EN

The research focuses on the preparation composite material containing glass powder of grain size (10-15)µ reinforced polyester with volume fraction 30%.

Many tests have been done in different temperature conditions including Bending test, Hardness, Impact and Thermal conductivity ( K ).

The results show that Young's modulus ( E ) decreases and fracture toughness ( Kc ) for composites increase with increasing temperature, but Brinnels hardness decreases with increasing temperature.

The result also shows that thermal conductivity ( K ) increases with increasing temperature.
