NOVELTY - High-temperature-resistant epoxy aramid fiber insulation layer and molded parts, i.e., complex materials prepared by hot-pressing at least one layers of high-temperature-resistant epoxy aramid fiber-fabric prepregs. The high-temperature-resistant epoxy aramid fiber-fabric prepreg is formed by impregnating aramid fiber-fabric with epoxy adhesive, and then baking it to form a high-temperature-resistant aramid fiber-fabric with a semi-cured material Epoxy aramid fiber-fabric prepreg. The aramid fiber-fabric is aramid fiber checkered cloth, aramid fiber twill cloth, aramid fiber plain cloth, aramid fiber satin cloth, aramid fiber stitched felt, aramid fiber continuous felt, aramid fiber complex cloth and aramid fiber complex felt. The high temperature-resistant epoxy adhesive comprises 12-45 pts. wt. epoxy resin, 5-35 pts. wt. modified epoxy resin, 1-61 pts. wt. filler, and 6-34 pts. wt. curing agent, 9.5-201 pts. wt. solvent, and 0.01-0.18 pts. wt. accelerator. USE - The high-temperature-resistant epoxy aramid fiber insulation layer and molded parts are useful for various engineering equipment, electrical equipment, corrosion-resistant appliances, new energy vehicles, etc., which have higher requirements for temperature resistance and are used for special purposes (aerospace, aerospace, high-performance ships, bulletproof, stab-proof, military) field application, high reliability, good performance and strong practicability.
