Abstract:
A process of forming a reinforcing lamina sheet for providing increased strength to a structural member comprising the steps of:unidirectionally orienting a first set of continuous filaments to form a generally planar band;impregnating the band with a curable thermosetting resin to form a substantially planar impregnated band having opposing first and second surfaces;tensioning the band; andcontacting the first surface of the impregnated band with a heated curved surface while maintaining the impregnated band under tension to at least partially cure said curable thermosetting resin in said band and at least partially set said band in a curved configuration;bending said partially cured band in a direction opposite the curvature of its curved configuration sufficient to fracture at least a portion of the first surface of the partially cured impregnated band.
