Effect of the volume fraction and curing time on thermal conductivity properties for some fibrous hybrid composites

Abstract

In this research a hand –lay up method was employed to prepare hybrid composites from epoxy resin rein forced with woven roving glass fiber at different volume fraction (20%,30%,40%).Thermal conductivity was measured at the above volume fractions and curing time (2h),(4h).Experimental results showed that ,the thermal conductivity values increase with increasing the volume fraction and curing time.
