NOVELTY - An epoxy resin fiber cloth is prepared by impregnating or coating epoxy resin adhesive and glass fiber cloth. The epoxy resin adhesive is prepared from 100 pts. wt. epoxy resin, 5-10 pts. wt. curing agent, 10-20 pts. wt. inorganic powder and 100-200 pts. wt.f solvent. The curing agent comprises dicyandiamide and modified phenolic resin in a weight ratio of 1:(2-4). USE - Epoxy resin fiber cloth used in laminated board (claimed) for copper-clad laminated boards, solar laminated boards and other electronic device. ADVANTAGE - The method can effectively avoid impact damage by adding composite fiber layer made of fiber cloth and adhesive. The addition of adhesive structure can promote impregnation and coating inside the fiber layer, and bonding with other layers, it reduces the problems of high temperature damage and powder loss, which is conducive to use of laminates in harsh environments such as high strength or high temperature. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: preparation of epoxy resin fiber cloth, which involves mixing the raw materials for preparing epoxy resin adhesive, soaking or spraying the mixture with glass fiber cloth, drying and hot-press molding; and application of epoxy resin fiber cloth in laminated board, which comprises protective layer, adhesive layer (A), battery layer, adhesive layer (B) and bottom layer from top to bottom. The epoxy resin fiber cloth is arranged between the protective layer and the adhesive layer (A) and/or between the adhesive layer (B) and the bottom layer.
