Embodiment

[0047] The operating time of each step of the process of the present invention is the order below to introduce the operation process of the process:

[0048] Before preparing samples, prepare materials and molds first, cut the prepreg fabric according to the design requirements, clean the mold, and apply the HR956 mold release agent produced by Xiamen Haoer Chemical Co., Ltd. The prepreg fabric used It is the P3252S-15 / 33 prepreg fabric produced by Toray TORAYA Company, and the forming temperature of the fabric is 150°C.

[0049] Since the mold is divided into the lower mold 1 and the upper mold 5 in this embodiment, and all the operation processes of the process described in this embodiment in the upper mold are included in the operation process of the process in the lower mold 1, therefore, this embodiment The embodiment only introduces the operation flow of the process in the lower mold 1 .

[0050] Such as figure 2 As shown, the composite material described in this embo...

Abstract

The invention belongs to the technical field of material preparation and relates to a prepreg mould-pressing composite material moulding process. The prepreg mould-pressing composite material moulding process aims to solve the problems that pinholes and aberration are generated on the surface of the composition material prepared by the conventional moulding process easily and the like. The invention provides a composite material moulding process. The composite material moulding process at least increases a step of adding a protective film on the surface of the composite material so as to solve the problems at the very least.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and relates to a composite material forming process. The forming process of the present invention at least adds a step of adding a protective film on the surface of the composite material so as to achieve the purpose of assisting the forming of the composite material. The composite material of the present invention Generally refers to the composite material produced by the prepreg molding process, which is mainly used for article decoration. Background technique [0002] The prepreg molding process has been widely used, and it has the characteristics of stable product performance, low resin content, strong designability, and easy operation. However, the surface of the formed product is prone to problems such as pinholes and chromatic aberration, and the appearance effect is poor. It is often necessary to repair the product in the post-processing process. Contents of the invention ...
