Problems solved by technology

[0003] However, in the above process, because the material moves forward uniformly, only workpieces with uniform cross-section and flat surface can be formed after passing through the cavity of the molding area 06, and it is still impossible to obtain a reliable mold shape for the molding of curved surfaces.

Abstract

The invention relates to the technical field of composite material pultrusion, in particular to a curved surface pultrusion piece forming method. The curved surface pultrusion piece forming method comprises the following steps: a first curved surface and a second curved surface which extrude the two sides of a pultrusion piece are arranged in sections; the sections in the two curved surfaces are sequentially attached to the surfaces of materials one by one after the materials are filled with resin and led out; after all the sections are attached, a complete curved surface is formed to extrudethe materials; the materials are cured and molded through heat conduction; and along with the introduction of new materials, the sections in the two curved surfaces are cyclically attached one by oneaccording to the sequence, so that the continuous production of curved surface pultrusion pieces is realized. According to the curved surface pultrusion piece forming method, the formed curved surfaceis circularly extruded in sections, continuous production of the curved surface pultrusion pieces is achieved, and the shape of the curved surface with stable size is obtained.

Description

technical field [0001] The invention relates to the technical field of composite material pultrusion, in particular to a method for forming curved surface pultrusion parts. Background technique [0002] Such as figure 1 As shown, the relatively conventional composite material pultrusion die at present includes a material inlet 01 and an outlet 02, wherein, after the material enters the inlet 01, the resin is injected through the injection port 03, and the release cloth 04 is introduced into the mold after the resin is injected. Covering the surface of the product, the product obtains different temperature gradients after passing through the heat insulation zone 05 and reaches the molding zone 06, and is finally heated and solidified and then drawn out from the outlet 02. [0003] However, in the above process, because the material moves forward uniformly, only workpieces with uniform cross-section and flat surface can be formed after passing through the cavity of the moldin...
