ABSTRACT:
An improved elongated blade or blade spar comprises successive low-pitch circumferentially wrapped convolutions of a synthetic resin impregnated tape having elongated cut glass and substantially parallel and equal length filaments wherein successive convolutions are overlapped approximately 50% and wherein the axis of the elongated strands lie at an angle of less than 30.degree. from the elongated spar axis. Preferably, resin impregnated filamentary strands are circumferentially wrapped around the mandrel substantially parallel with the direction of the tape wrap between selected tape layers. The improved blade spar mandrel wrapping apparatus includes a split ring support for the mandrel and through which the mandrel extends. The support ring halves may be separated, moved and rejoined during the mandrel wrapping process.
