The results obtained with regard to the physical and mechanical properties revealed that the EP/30TSPF/70GF composites exhibited the best physical and mechanical properties by increasing the tensile strength by 55.7%, flexural strength by 46.8% and compressive strength by 36.7% when comparing with EP/UTSPF composites.
