MANUFACTURE OF HOLLOW COMPOSITE MEMBER

摘要

PURPOSE:To manufacture a hollow composite member inclusive of a long product or a special hollow product by easy release work. CONSTITUTION:In a method for manufacturing a hollow composite member by winding a composite material prepreg round a core material, the core material composed of a heat shrinkable material is covered with an inside bag material and the composite material prepreg is wound round the outer periphery of the inside bag material and the outer periphery of the composite material prepreg is covered with an outside bag material 14 and the composite material prepreg is heated while respectively pressurized from the inside and outside thereof through the inside and outside bag materials. Further, the composite material prepreg. is wound round the outer periphery of the inside bag material while the core material is supported by a rigid shaft.
