Carbon fiber enhanced composite material panel and preparation method thereof

Abstract

The invention discloses a carbon fiber enhanced composite material panel and a preparation method thereof. The carbon fiber enhanced composite material panel structurally comprises at least five layers, the thickness is 0.8mm to 20mm; the first layer is natural sliced wood veneer, the second layer is a nonwoven fabric layer, the third layer is a first carbon fiber, the fourth layer is a second carbon fiber, and the fifth layer is a third carbon fiber or natural sliced wood veneer. The composite material panel formed by adopting the scheme has the beneficial effects that the weight is light, the strength is high, and the grains of the surface are natural and plentiful; as the whole sheet is made by carbon, epoxy resin and wood veneer all of which are nontoxic and harmless products, the environment protection performance is good. The product is widely applied to the fields of shells of electronic products and interior trim parts of automobile, particularly, the application prospect of the product is very wide under the background of vigorous development of the electric car industry in our country at present; products in various shapes can be formed by different molds, so that the composite material is the preferred material in the automobile lightweight technical field.

Description

Technical field [0001] The invention belongs to the technical field of carbon fiber composite materials, and specifically relates to a carbon fiber reinforced composite material plate and a preparation method thereof. Background technique [0002] There are currently three types of carbon fiber composite materials on the market. The first type: the upper and lower surfaces are made of carbon fiber woven prepregs, and the middle is made of carbon fiber unidirectional prepregs, which are pressed by a hot pressing process, and the surface has a 3K carbon fiber woven texture. ; The second type: the use of carbon fiber unidirectional prepreg, which is pressed by a hot pressing process, and the surface is pure black texture; the third type: both the inside and outside are made of carbon fiber woven prepreg, hot pressed. The first and third types are woven fabrics with carbon fiber surfaces with plain, twill or satin textures, while the second type has no texture and has a black surface...

AI Technical Summary

Problems solved by technology

These three kinds of plates are widely used in fields that do not require high decoration, but require high strength and light weight. Since the carbon fiber woven cloth has only three textures: plain weave, twill weave and satin weave, and most of them are black, some are not suitable for decoration. For occasions where performance, strength and weight are required, such as the casing of some electronic products, the interior parts of automobiles, or the decorative panels of drones and aircrafts, the appearance of materials made of carbon fiber woven fabrics and unidirectional fabrics is uniform. Difficult to meet demand for these products
