▎ 摘　　要

NOVELTY - Bismaleimide resin complex material comprises 35-60 pts. wt. o-diallyl bisphenol A, 30-60 pts. wt. bismaleimide resin, 1-3 pts. wt. accelerator, and 0.05-1.5 pts. wt. graphene. USE - The bimaleimide resin composite material is useful for carbon fiber prepreg, which is useful in aerospace field. ADVANTAGE - The bismaleimide resin composite material has good viscosity, and is good for the prepreg with better impact resistance after curing. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the bismaleimide resin composite material comprising (i) taking o-diallyl bisphenol A, bismaleimide resin, accelerator and graphene, (ii) baking the o-diallyl bisphenol A to a fluid state, keeping stirring at 50-80°C in a high-speed disperser, and adding accelerators and graphene during the process, mixing well for 15-30 minutes, and (iii) transferring the mixture to the reaction kettle, and after the temperature rises to 80-100℃, gradually adding the bismaleimide resin into the reaction kettle, and heating it at the temperature, stirring for 30-60 minutes, mixing and discharging; carbon fiber prepreg tape, comprising bismaleimide resin; and preparing prepreg tape comprising continuously dipping and winding the carbon fiber belt through bismaleimide resin and methylene dichloride mixed solution, placing for more than 6 hours at room temperature, and obtaining the carbon fiber prepreg.
