  Abstract

In the present study, the effect of electron beam irradiation on the tensile, dynamic mechanical, and abrasion properties of glass-fiber-reinforced diepoxidized polycardanol (DEPC) composites was explored. Triarylsulfonium hexafluoroantimonate, an antimonate-type photoinitiator (2 wt%) was added to diepoxidized cardanol (DEC) prior to composite curing by electron beam. The glass fabrics pre-impregnated with DEPC were consolidated by direct irradiation of electron beam at 400, 500, and 600 kGy at ambient temperature and pressure. The composite properties strongly depend on the applied electron beam intensity. The result indicates that electron beam curing of glass fiber/DEPC composites at 600 kGy resulted in the highest tensile modulus, tensile strength, dynamic storage modulus, abrasion resistance, and lowest damping among the applied electron beam absorption doses.
