NOVELTY - System comprises 100 pts. wt. benzoxazine resin, 5-20 pts. wt. epoxy resin, 5-20 pts. wt. diluting agent, 0-20 pts. wt. curing agent and 0.01-0.05 pts. wt. imidazole modified graphene oxide, where the benzoxazine resin is a MDA type benzoxazine, bis-amine type benzoxazine and/or p-cresol type benzoxazine, the epoxy resin is a liquid epoxy resin, and the curing agent is a liquid aromatic amine curing agent. USE - The system is useful for wet winding process. ADVANTAGE - The system increase the curing crosslink density of benzoxazine resin by using liquid epoxy resin, improves heat resistance, increases compatibility of various components, impart good toughness and process performances by reactive diluents, liquid curing agents and toughening agents; has moderate viscosity and long application period; and meets the requirements of wet winding process. The prepared product has better heat resistance, mechanical properties, simple preparation process and has low production cost.
