Abstract:
1. A process for fabricating a laminate polymer composite material that comprises a polymer matrix containing multiple reinforcement fabrics and particles of a filler material, the polymer matrix being formed by curing a resin, the process comprising: providing at least two articles that each comprise at least one of the reinforcement fabrics, wherein the articles do not contain the resin, the reinforcement fabrics thereof are dry, and spaces are present between adjacent fibers of the reinforcement fabrics; applying means to each of the articles for promoting adhesion of the particles of the filler material to the articles; spraying the particles of the filler material on each of the articles so that each of the articles individually forms a particle-laden article in which the particles of the filler material are adhered thereto by the adhering means applied thereto, wherein the particle-laden articles do not contain the resin, the reinforcement fabrics thereof are dry, and the spraying step causes the particles of the filler material to penetrate the reinforcement fabrics and be adhered to the reinforcement fabrics by the adhesion-promoting means applied thereto; stacking the particle-laden articles to form a stacked structure, wherein the stacked structure does not contain the resin and the reinforcement fabrics thereof are dry; infusing the resin into the stacked structure; and curing the resin present within the stacked structure to form the laminate polymer composite material comprising the reinforcement fabric and the polymer matrix formed by curing the resin.
