A method of manufacturing a continuous fiber composite shell

Abstract

The invention discloses a method for manufacturing a continuous fiber composite material shell. The manufacturing process comprises the following steps: (1) driving a thermoplastic material extrusionmechanism to print a core mold on a printing platform according to a pre-designed structure by a motion module, wherein a resin runner aligned at a liquid through hole is formed in the core mold; (2)driving a winding mechanism and the printing platform to wind dried continuous fibers on the printed core mold according to a design path by the motion module so as to obtain a preform; (3) covering avacuum film on the continuous fiber preform by a laminating mechanism, wherein the resin runner in the lower part of the preform is communicated with the liquid through hole and the continuous fiberarea, the resin runner in the upper part of the preform is communicated with the continuous fiber area, and a resin orifice is formed in the top; (4) pumping the resin liquid tank with resin liquid, starting a vacuum pump of a vacuum auxiliary unit, and enabling the resin liquid to gradually transfer to the top from the bottom of the continuous fiber preform; (5) removing the structural componentfrom the printing platform after resin curing, and resetting each module. Therefore, the whole operating process is ended.

Description

technical field [0001] The invention relates to the technical field of continuous fiber composite material manufacturing, in particular to a method for manufacturing a continuous fiber composite material shell. Background technique [0002] As a strategic material for national development, carbon fiber has excellent characteristics such as high strength, high stiffness, low specific gravity, friction and wear resistance, and recyclable use.

Problems solved by technology

[0004] The above method and device focus on solving the problem of how to realize the mixing and printing of continuous carbon fiber thermoplastic materials. However, due to the layer-by-layer process characteristics of additive manufacturing technology, the mechanical properties of continuous fiber composite materials in the printing direction are poor; in addition, printing Structural parts are also subject to the influence of thermoplastic material matrix properties, and their mechanical properties still have a large gap compared with structural parts manufactured by traditional continuous carbon fiber composite manufacturing process
