A fully impregnated fiber-reinforced thermoplastic granule includes a fiber core impregnated with a thermoplastic resin and coated with the resin and subsequently polymerized to form a thermoplastic. The granule is formed in a continuous process including a continuous fiber strand being coated and impregnated with a thermoplastic resin, curing the thermoplastic resin, and cutting the fiber and thermoplastic into granules of a desired length. The continuous process results in a uniform, fully impregnated fiber core in the granule which results in a longer reinforcing fiber for added strength in subsequently produced products formed from the granules.
