Process of fabricating a laminated hollow composite cylinder with an arranged ply angle

摘要

A manufacture method of a laminated hollow composite cylinder with an arranged ply angle is disclosed. The fiber in the hollow composite cylinder can be arranged in an angle Phi between 30° and 60° according the applications. Prepregs were cut into fan-shaped pieces and laminated in a metal mold to form an annular lamina assembly. The metal mold comprises a concave female mold and a convex male mold that both have a tapered angle complying with the ply angle Phi. Hot press molding with pressure over 140.6 kg/cm² was then used for solidifying the lamina assembly to produce the composite hollow cylinders with the ply angle Phi. The laminated hollow composite cylinder can achieve excellent thermal and mechanical properties to meet design requirements.
