Abstract: A sizing composition and method for manufacturing such, which is suitable for use in manufacturing fiber-reinforced composites which have desirable properties such as high strength, high resistance to water and chemical degradation, and improved coloring. This is achieved in part by good adhesion of the sizing composition to the reinforcing fibers and the polymer matrix.

Abstract: With the hardener particle of the present invention, because siloxane or an alkoxy group is bonded to a central metal located on a surface, an adhesive prepared by dispersing the hardener particles in an epoxy resin together with a silane coupling agent hardly causes reaction between the hardener particles and the silane coupling agent at ambient temperature whereby the preserving property of the adhesive is high. Because no siloxane is bonded to metal chelate or metal alcoholate at the part other than the surface of the hardener particles, the hardener particles are broken when the adhesive is heated, and the metal chelate and the metal alcoholate on the part other than the surface of the hardener particles reacts with the silane coupling agent to form cation, thereby polymerizing the epoxy resin with the cation to harden the adhesive even at low temperature within shorter time.
