Description

technical field [0001] The invention relates to a new method in the technical field of processing and molding of high-resolution materials, in particular to a cured resin for preparing carbon fiber composite materials and its application. Background technique [0002] Olefin polymers are a new type of green engineering plastics, which can be obtained from petroleum cracked olefin polymer monomers through ring-opening shift polymerization. Olefin polymer materials are light in weight and have excellent comprehensive properties, especially excellent mechanical properties, high modulus, high impact resistance and high creep resistance. Combined with Reaction Injection Molding (RIM), it can not only retain the excellent balance of toughness and rigidity of olefin polymers, but also can effectively prepare key parts of automobiles. It is becoming a new type of high-impact material to replace current engineering plastics. Carbon fiber is a key composite material for a new generat...
