LEAF SPRING OF FIBERGLASS REINFORCED PLASTICS FOR CAR

摘要

PURPOSE:To obtain leaf spring of fiberglass reinforced plastics for car provided with heat resistance and fatigue resistance, by impregnating a fibrous reinforcement material with a resin compound of acid anhydride and epoxy resin composed of bisphenol type and fat-ring type and by allowing it to harden in a form. CONSTITUTION:One or more sorts of fibrous reinforcement material selected from groups of glassfiber, carbonic fiber and aromatic polyamid fiber is impregnated with a resin compound of acid anhydride and epoxy resin composed of 95-30wt% bisphenol type epoxy resin with the mean epoxy equivalent ranging from 150 to 300 and 5-70wt% fat-ring type epoxy resin, with or without accelerant according to need, and then they are allowed to harden in a form.
