ABSTRACT:
A formable prepreg, and a method of making a formable prepreg by a pultrusion process. The method includes (a) impregnating reinforcing fiber with a thermosetting resin matrix, and (b) passing the resin impregnated reinforcing fiber through a die within which the resin impregnated reinforcing fiber is subjected to conditions sufficient to thicken the thermosetting resin matrix, to provide a formable prepreg. The present invention also provides a method of making a molded article using the prepreg of the present invention.
