Abstract

The invention discloses a carbon fiber processing method and a carbon fiber product, and the method comprises the following steps: opening a hot pressing mold; performing demoulding treatment on the surface of the cavity of the hot pressing mold; laying glass fiber prepreg cloth on one surface of the cavity of the hot pressing mold; laying a carbon fiber prepreg cloth lamination layer, which is provided with an opening at a preset position of signal equipment, on the glass fiber prepreg cloth; filling the opening arranged in the carbon fiber prepreg cloth lamination layer with the glass fiber prepreg cloth or a thermoplastic resin or a thermosetting resin; closing the hot pressing mold for compression moulding forming and high pressure forming of a product; and opening the hot pressing mold to take the product. The product is produced from processing by the processing method. According to the carbon fiber processing method and the carbon fiber product, when carbon fiber is used as a 3C (computer, communication and consumer electronics) product appearance part, the poor signal reception problem of antennas and other signal equipment due to only use of the carbon fiber can be solved, and lightweight, thin and high rigidity appearance products can be obtained.

Description

【Technical field】 [0001] The invention relates to a carbon fiber, in particular to a carbon fiber processing method and a product thereof. 【Background technique】 [0002] As people increasingly pursue high-quality life, people pay more and more attention to the shape and appearance decoration effect of household products. Therefore, the current development trend of 3C products is to develop in the direction of thinner, lighter and higher rigidity. Therefore, various fiber reinforced materials are gradually paid attention to. [0003] Generally, fiber reinforcement is achieved by adding glass fibers to plastic materials or impregnating epoxy resin with hot-pressed carbon fibers. Although carbon fiber is superior to glass fiber in rigidity, due to the conductivity of carbon fiber, the appearance of 3C products made of carbon fiber will have electromagnetic shielding problems, and signal equipment such as antennas of 3C products will have poor signal reception, which limits th...
