AI Technical Summary

Technical Problem

Traditional transparent fiberglass covers are prone to uneven deformation and stress concentration when transforming into 3D shapes with high arc-to-height ratios, resulting in appearance defects such as localized whitening and fogging, making it difficult to meet the requirements of appearance transparency and structural reliability for high-end electronic products.

Method used

The structure employs a layered base composite layer and a reinforcing composite layer. The base composite layer is composed of unidirectional glass fibers with high resin content and fine fiber diameter, while the reinforcing composite layer is composed of unidirectional glass fibers with low resin content and coarse fiber diameter. The two layers work together to ensure a stable refractive index match between the resin and the glass fiber, avoiding uneven deformation and stress concentration.

Benefits of technology

It achieves a high arc-to-height ratio 3D model, avoiding problems such as localized whitening and fogging caused by uneven deformation and stress concentration, and has good appearance reliability and structural stability, meeting the needs of high-end electronic products.

Abstract

The application relates to the technical field of electronic equipment. Specifically, the application relates to a transparent glass fiber structural member, a preparation method thereof and electronic equipment. The transparent glass fiber structural member comprises a base composite layer and a reinforcing composite layer which are arranged in a stack; the base composite layer comprises at least two base surface layers arranged in a stack; and the reinforcing composite layer comprises at least two reinforcing surface layers arranged in a stack. The base surface layer comprises a first resin and first unidirectional glass fiber filaments dispersed in the first resin; and the reinforcing surface layer comprises a second resin and second unidirectional glass fiber filaments dispersed in the second resin. The mass fraction of the first resin in the base surface layer is higher than that of the second resin in the reinforcing surface layer; and the fiber diameter of the first unidirectional glass fiber filaments in the base surface layer is lower than that of the second unidirectional glass fiber filaments in the reinforcing surface layer. The transparent glass fiber structural member can avoid uneven deformation, local whitening and misting caused by stress concentration, and has good appearance reliability.
