摘要
A hollow, stiff, one-piece filament-reinforced composite mandrel of nonuniform wall thickness for a wind turbine blade spar is comprised of bonded inner and outer filament-reinforced shells. The inner shell is fabricated by bonding together separately formed tubular halves. The outer shell is built up on the outer surface of the inner shell preferably by judicious winding of a plurality of turns of filament-reinforced epoxy resin material.
