Abstract
Processes for fabricating polymer composite materials that contain a polymer matrix, reinforcement fabrics, and particles of a filler material. The processes include spraying the particles of the filler material on at least two articles that each comprise at least one of the reinforcement fabrics to form particle-laden articles. The particle-laden articles are stacked to form a stacked structure, and a resin present within the stacked structure is then cured to form a laminate polymer composite material. The process can be employed in the fabrication of at least a portion of an aircraft engine nacelle, for example, the inlet lip of a fan nacelle.
