Composite fiber material product, preparation method thereof and application thereof

Abstract

The invention discloses a composite fiber material product, a preparation method thereof and an application thereof. The composite fiber material product comprises a piece of middle fiber material cloth (1), an upper surface film (2) arranged above the fiber material cloth (1) and a lower surface film (3) arranged under the fiber material cloth (1), wherein the outer surfaces of the upper surface film (2) and the lower surface film (3) are further provided with a layer of glass fiber cloth (4). The upper surface film and the lower surface film of the composite fiber material product can be respectively and internally printed with characters or patterns, the surfaces can be respectively formed to be a mirror surface or matting, and the composite fiber material product is attractive in appearance, free of air vents and needle eyes, good in rigidity, strong in impact resistance and mar resistance, and strong in heat resistance and corrosion resistance, so that the composite fiber material product can be widely used for manufacturing shells of various electronic products, electrical equipment, aviation and spaceflight equipment, and the like. The preparation method of the composite fiber material product is low in mould requirement, can be used for preparing the composite fiber material product with a surface which has the mirror surface or is matting. The follow-up treatment to the surface of the product can be avoided, such as polishing and the like, so that the invention is convenient to operate, and high in yield and production efficiency.

Description

technical field [0001] The invention relates to a fiber material panel product, in particular to a composite fiber material product, its preparation method and its application in the preparation of aerospace equipment, electronic products or electrical product shells. Background technique [0002] With the rapid development of China's economy, various electrical appliances, electronic products, motor vehicles and aerospace equipment have developed rapidly, and people are gradually pursuing high-quality life. The equipment shells of these products generally require strong hardness, strong impact resistance, and durability Heat and corrosion resistance, carbon fiber products in the prior art have been widely used, but the carbon fiber products in the prior art have poor aesthetics, uneven surface, and often have more porous pinholes on the surface, which leads to its anti-scratch Poor performance and corrosion resistance, can not meet the requirements of high surface flatness ...

[0002] With the rapid development of China's economy, various electrical appliances, electronic products, motor vehicles and aerospace equipment have developed rapidly, and people are gradually pursuing high-quality life. The equipment shells of these products generally require strong hardness, strong impact resistance, and durability Heat and corrosion resistance, carbon fiber products in the prior art have been widely used, but the carbon fiber products in the prior art have poor aesthetics, uneven surface, and often have more porous pinholes on the surface, which leads to its anti-scratch Poor performance and corrosion resistance, can not meet the requirements of high surface flatness and high impact resistance, scratch resistance and corrosion resistance standards, and the preparation methods of carbon fiber panel products in the prior art often include spreading, entering the mold, Applying resin, molding and surface treatment or prepreg laying, mold feeding, molding, surface treatment, etc., these fiber panel product preparation methods in the prior art all have high mold requirements, high cost, and low authenticity rate, especially the need The surface of the prepared carbon fiber and other panel products is polished or painted to make the surface achieve mirror or pinhole-free effects. This kind of surface treatment process is complicated, requires a lot of manpower and material resources, and the work efficiency is low. During the surface treatment process, it is easy to cause secondary damage to the panel and reduce the qualified rate of finished products
