▎ 摘　　要

NOVELTY - Composite thermally and electrically conductive material based on the carbon fiber molding of active screen plasma nitridation (ASPN) processing technology comprises 300-500 pts. wt. modified carbon fiber, 1-5 pts. wt. toughening agent, 500-1000 pts. wt. thermally conductive powder, 1-2 pts. wt. plasticizer, 1-5 pts. wt. antioxidant, and 0.5-2 pts. wt. compatibilizer. The carbon fiber raw material of the modified carbon fiber is carbon fiber filament, carbon fiber bundle, carbon fiber cloth, carbon fiber paper or carbon fiber fabric. USE - Used as composite thermally and electrically conductive material based on the carbon fiber molding of ASPN processing. ADVANTAGE - The material meets the quality requirements of solid interface bonding, and also enables the reinforcement phase, which accounts for a large mass ratio of carbon fiber composites with wave-absorbing function, and greatly improves the performance of the composite thermally and electrically conductive material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing composite thermally and electrically conductive material comprising (S1) modifying the carbon fiber raw material based on ASPN treatment to obtain modified carbon fiber, (S2) uniformly mixing the modified carbon fiber with a toughening agent, a thermally conductive powder, a plasticizer, an antioxidant and a compatibilizer to obtain a carbon fiber mixture, (S3) driving the carbon fiber mixture into the forming tank by a non-clogging pump, immersing the mold with holes in the slurry tank, and vacuum filtering, (S4) taking out the formed carbon fiber mixture from the perforated mold, and drying the carbon fiber mixture, and (S5) hot-pressing the dried carbon fiber mixture to obtain a carbon fiber composite thermally and electrically conductive material.
