Puncture-healing thermoplastic resin carbon-fiber-reinforced composites

摘要

A composite comprising a combination of a self-healing polymer matrix and a carbon fiber reinforcement is described. In one embodiment, the matrix is a polybutadiene graft copolymer matrix, such as polybutadiene graft copolymer comprising poly(butadiene)-graft-poly(methyl acrylate-co-acrylonitrile). A method of fabricating the composite is also described, comprising the steps of manufacturing a pre-impregnated unidirectional carbon fiber preform by wetting a plurality of carbon fibers with a solution, the solution comprising a self-healing polymer and a solvent, and curing the preform. A method of repairing a structure made from the composite of the invention is described. A novel prepreg material used to manufacture the composite of the invention is described.

1. A composite comprising a combination of a self-healing polymer matrix and a carbon-fiber reinforcement, wherein the composite is fabricated from an intermediate prepreg material, wherein the composite does not comprise microcapsules containing a healing agent, nor hollow glass fibers containing a healing agent, and wherein the composite exhibits an average fiber volume fraction (FVF) of greater than 60%.
