Abstract

The invention relates to the technical field of printed circuit boards, in particular to a carbon fiber base fabric composite material. The carbon fiber base fabric composite material comprises at least one layer of carbon fiber base fabric and adhesive layers. The adhesive layers are one layer more than the carbon fiber base fabric. The composite material is formed by the carbon fiber base fabric and the adhesive layers through alternately laminating in a press fit mode. The carbon fiber base fabric is made of carbon fiber through knitting in the warp and weft direction. Compared with a glass fabric base fabric bonding sheet, the carbon fiber base fabric composite material has better thermal conductivity, overcomes the defects that weft skewing can easily happen to a carbon fiber sheet and production operations of the carbon fiber sheet is hard, greatly improves warping of products, and particularly improves the stability of the sizes of the products.

Description

technical field

[0001] The invention relates to the technical field of printed circuit boards, in particular to a carbon fiber cloth-based composite material and its preparation and application. Background technique

[0002] Copper-clad laminate (CCL) is a product that combines reinforcing materials and copper foil with epoxy resin as a fusion agent. Most of the traditional reinforcing materials are glass fiber cloth, and a small amount of paper or composite materials are used. The glass fiber cloth is made of glass fiber. The glass fiber cloth substrate made of glass fiber cloth has higher mechanical properties, dimensional stability, impact resistance, and moisture resistance than paper base, and its electrical properties are excellent, the working temperature is high, and its performance is affected by the environment. Small impact. However, its thermal conductivity is not good. Under the trend of electronic products becoming more and more thin and small, the adhesive sh...
