Method of improving adhesion of carbon fibers with a polymeric matrix
Abstract
A method of making a solid composite containing carbon fibers embedded in a polymeric matrix, the method comprising admixing carbon fibers with a polymer precursor resin, and curing the polymer precursor resin to form a cured polymeric matrix that contains said carbon fibers embedded therein, wherein said carbon fibers have covalently bonded on their surfaces a partially cured epoxy-containing or amine-containing sizing agent, wherein at least a portion of epoxide groups or amine groups in the sizing agent are available as uncrosslinked epoxide groups or amine groups, which corresponds to a curing degree of epoxide groups or amine groups of no more than about 0.6.
