AI Technical Summary

Technical Problem

During the preparation of fiber materials, compression molding of spherical structures can easily lead to wrinkles in prepregs, fiber dislocation and separation, which are difficult to effectively solve with existing technologies.

Method used

Simulation software is used to analyze the prepreg molding process, identify sensitive areas, and set a tensioning device in the mold to tension the prepreg. The tensioning device is used to locate and tension the sensitive areas of the prepreg to avoid the formation of defects such as fiber wrinkles, fiber separation, and fiber deformation.

Benefits of technology

It effectively avoids local deformation and displacement of prepreg during the molding process, improves the yield rate of composite materials, and ensures the smooth surface and stable structure of the product.

Abstract

The present invention discloses a composite material preparation method, a composite material and an electronic device. The preparation method comprises: using simulation software to simulate and analyze the molding process of a prepreg to determine sensitive areas that are prone to defects; according to the simulation analysis results, a tensioning device is provided outside a portion of the mold corresponding to the sensitive area, and the tensioning device is used to tension the sensitive area of ​​the prepreg; the prepreg is placed in the mold, the tensioning device is used to tension the prepreg, and hot pressing is performed. The use of simulation software can effectively determine the sensitive areas of the prepreg during the molding process, that is, the areas that are prone to defects. By pre-arranging a tensioning device on the mold outside the area and connecting the tensioning device to the prepreg, the prepreg can be effectively positioned and tensioned.
