Method of improving adhesion of carbon fibers with a polymeric matrix
Abstract
A method of making a carbon fiber having on its surface a partially cured sizing agent, the method comprising covalently binding on the surface of said carbon fiber a sizing agent comprised of an epoxy resin, and partially curing said sizing agent by contact thereof with a curing agent such that at least a portion of epoxide groups remain uncrosslinked on said surface, which corresponds to a curing degree of epoxide groups of no more than about 0.6, and further comprising reacting at least a portion of said epoxide groups with a bifunctional molecule that contains first and second reactive groups, the first reactive group being reactive with and forming a covalent bond with the epoxy group, and the second reactive group being unsaturated and accessible for reaction with a carbon-carbon double bond of an unsaturated resin via a vinyl addition reaction.
