n (RP) A plastic composition in which are embedded fibers that are much stronger and typically much stiffer than the matrix resin. The reinforcements are usually fibers, rovings, fabrics, or mats, or mixed forms of glass, carbon, asbestos, metals, ceramics, paper, sisal, cotton, or nylon. Resins most commonly used are polyesters, phenolics, aminos, silicones, epoxies, and various thermoplastics. The term reinforced plastic includes some forms of Laminate and molded parts in which the reinforcements are not in layered form. When the resin is thermoplastic, the term reinforced thermoplastic is often used. Methods of forming reinforced-plastics articles from thermosetting resins are defined under the entries listed below.
