Remolding-realizable carbon fiber sheet material with weaving texture on whole surface and preparation method thereof

Abstract

The invention relates to a remolding-realizable carbon fiber sheet material with a weaving texture on a whole surface. The remolding-realizable carbon fiber sheet material comprises a carbon fiber sheet main body, wherein the carbon fiber sheet main body comprises multiple thermosetting carbon fiber prepreg layers and a filled interlayer; the glass bead filled interlayer is arranged in the middleof the multiple thermosetting carbon fiber prepreg layers; the carbon fiber sheet material also comprises a thermoplastic carbon fiber woven fabric prepreg layer arranged at the uppermost layer of thecarbon fiber sheet main body; moreover, the edge of the thermoplastic carbon fiber woven fabric prepreg layer is in an arc shape. The sheet material provided by the invention has favorable strength and rigidity below the softening point of a base material, and also has plasticity anew above the softening point; due to the arc-shaped structure of the edge, when the sheet material is subjected to subsequent processing or combined with other structures, the weaving texture of the entire surface can be maintained; the post forming processing speed of the remolding-realizable carbon fiber sheet material is quick; the production efficiency is high; the production cost is low; the large-batch production can be realized; the impact resistance is good; a product can have post forming ability, andthe remolding-realizable carbon fiber sheet material has the carbon fiber weaving texture on the whole surface.

Description

technical field [0001] The invention relates to the field of composite material manufacturing, in particular to a remodelable carbon fiber plate with woven texture on the entire surface and a preparation method thereof. Background technique [0002] With the development of electronic lightweighting, traditional aluminum-magnesium alloy materials cannot meet the requirements. For example, notebook computers have dropped from traditional products to less than 1 kg, and iPads have to develop from 900 grams to 700 grams or even 500 grams. are becoming stronger and stronger, so there is an urgent need for new materials to solve them. Carbon fiber composite materials have the advantages of light weight, high strength, low thermal expansion coefficient, and corrosion resistance. Materials have also been tried as the casing of electronic products. [0003] A carbon fiber sheet with a publication number of CN106183135A discloses: a carbon fiber sheet, including no more than six lay...

AI Technical Summary

Problems solved by technology

However, at present, carbon fiber composite materials used in electronic products such as notebook computers, and interior and exterior decorative panels of automobiles are limited by materials, designs, and processes, and do not have a woven texture on the entire surface, which destroys the integrity of the overall appearance.
