Abstract : The invention relates to improved filament-wound structural laminates in which the filament windings are bonded with cured epoxy resins. It also relates to a method of impregnating continuous strands of high modulus, nonmetallic inorganic filaments with high molecular weight, flexible, thermoplastic organic polymers. Filament-wound glass fiber structural laminates in which the binder is a cured epoxy resin have low stress distribution due to the hard nature of the cured resin. It is a particular object to provide improved stress distribution in filament-wound structural laminates of glass or other high modulus, nonmetallic, inorganic filament windings which are bonded with cured epoxy resins through the inclusion therein of a tough, flexible plastic which encapsulates the filaments and intervenes between the filaments and the cured epoxy resin binder.
