Embodiment approach
[0053] In a specific embodiment, the method specifically includes the following steps:
[0054] Step 1: Lay the advanced composite material on the surface of the mold to form an L shape;
[0055] First, according to the size requirements of the advanced composite L-shaped beam member, the advanced composite material is laid on the surface of the mold. The mold is used to provide the L-shaped advanced composite material L-shaped beam member. In order to facilitate the preparation of the advanced composite material L-shaped beam member , before laying the advanced composite material, first lay the release film and the release cloth on the surface of the mold, then lay the advanced composite material, and finally lay the release cloth and air felt on the surface of the advanced composite material.

Abstract
The invention provides a method and device for preparing an advanced composite material L-shaped beam component through an autoclave. The method for preparing the advanced composite material L-shaped beam component through the autoclave comprises the following steps that an advanced composite material is laid on the surface of a mold to form an L shape; the surface, where the advanced composite material is laid, in the mold is covered with a vacuum bag, and air between the mold and the vacuum bag is pumped out; and molding and curing treatment is performed on the advanced composite material in the autoclave to obtain the advanced composite material L-shaped beam component. The mode that one face of the mold is covered with the vacuum bag replaces a full wrapping mode, edges and corners in the mold are avoided, the problem that the vacuum bag is cut by the edges and corners of the mold is avoided, the bridging phenomenon is avoided, the attaching degree of the vacuum bag and the mold is guaranteed, and preparation of the advanced composite material L-shaped beam component is guaranteed.
Description
technical field [0001] The invention relates to a method and a device for preparing an L-shaped beam member of an advanced composite material through an autoclave, and relates to the technical field of material processing. Background technique [0002] Composite material is a new material formed by optimizing the combination of different material components. Among them, the advanced composite material obtained with resin as matrix and continuous fiber as reinforcement has the characteristics of light weight, high strength and designability. , aerospace and other high-tech fields have been widely used. [0003] The L-shaped beam member of advanced composite material is a typical component of advanced composite material. It is mainly obtained by forming an L-shaped advanced composite material through an L-shaped mold and then curing it. Specifically, laying the advanced composite material on the surface of the mold, The L-shape is formed, and then molded and solidified under ...
