发明名称 METHOD AND APPARATUS FOR BENDING COMPOSITE REINFORCED PIPE
摘要 An induction heater is used to heat composite reinforced pipe (CRP) prior to a bending operation. By heating the composite reinforcement to approximately 90° F-110° F, the incidence of circumferential stress cracks in the resin is significantly reduced. Resin cracking is also reduced by incorporating longitudinal fibers in the composite reinforcement during manufacture of CRP.
