COMPRESSION MOLDED COMPOSITE MATERIAL FIXED ANGLE ROTOR

摘要

A method and apparatus for compression molding of fiber fixed angle rotors. Female mold (F) defines cylindrical bore (14) for molding the bottom of the rotor. Bore (14) defining frustum shaped central cavity (C) complementary to and concentric with the spin axis of the rotor. Male mold (M) contains frustum shaped inner cavity (C) with the apex of frustrum (18) disposed to the inner portion of bore (14) and the base of frustum (18) exposed to the cylindrical opening of mold (F). Inner cavity (C) defines the exterior shape of the rotor and defines between the exterior profile and the inner cavity (C) a rotor body wall. At the apex of inner cavity (C) there is a lock system for maintaining cores (K) in alignment with sample tubes of the rotor. Loading with resin pre-impregnated fiber occurs in inner cavity (C) and at the bottom of mold (F).
