| titleOfInvention | A kind of preparation method of micro-nano particle synergistic interlayer toughening dual horse/carbon fiber composite material |
| abstract | The invention relates to a preparation method of micro-nano particle synergistic interlayer toughening dual-horse/carbon fiber composite material, which solves the technical problem of complicated process existing in the existing dual-horse prepreg and interlayer toughening technology of composite materials, It disperses thermoplastic micro-particles and core-shell nanoparticles in a liquid toughening agent composed of an allyl compound and epoxy resin, then adds bismuth micro-powder for pre-mixing, and then places it on a three-roll mill for physical blending; then The coating film is compounded with carbon fiber reinforcement by hot pressing and pre-impregnation, and the prepreg enriched with multi-scale micro-nano particles on the surface of the reinforcement and between the bundles is obtained by the sieving of the fibers; of composite materials. The technical scheme of the present invention improves the manufacturability of the prepreg, and also improves the interlaminar fracture toughness of the composite material. |
