Title:
MANUFACTURING METHOD FOR AND STRUCTURE OF LIGHTWEIGHT COMPOSITE THRUST ROD
Document Type and Number:
WIPO Patent Application WO/2022/170653
Kind Code:
A1
Abstract:
A manufacturing method for and structure of a lightweight composite thrust rod. A tool (2) comprising a central body (22) and a pressing block (23) is first disposed, and then after a strip-shaped continuous fiber reinforced thermoplastic composite material is wound around the periphery of the central body (22) multiple turns, a continuous special-shaped peripheral layer reinforcement (11) which is closed in the peripheral direction is formed by pressing by means of the pressing block (23); then the peripheral layer reinforcement (11) is filled with a long fiber reinforced thermoplastic composite material or a short fiber reinforced thermoplastic composite material by means of injection; finally, rubber metal ball hinges (13) are pressed into the two ends to form a complete thrust rod (1). The thrust rod (1) formed by the method is superior in performance and higher in strength, can bear larger tensile strength and is not easy to tear; moreover, a U-shaped edge covering structure is arranged at the edge of the peripheral layer reinforcement (11), so that the welding strength of two different materials is ensured, and the overall fatigue performance of the thrust rod (1) is also superior.
