US 2018/0169976 A1 · METHOD FOR SELECTIVE PLACEMENT OF REINFORCING FIBERS IN POLYMERIC COMPONENTS

Abstract

A method of forming a reinforced polymeric component includes securing a plurality of pins within a mold and wrapping reinforcing fibers around the pins to form a web of reinforcing fibers. The web of reinforcing fibers has a plurality of layers. The method of forming a reinforced polymeric component further includes adding a polymer to the mold and processing the polymer to form a molded polymeric component that contains the pins and the web of reinforcing fibers. A reinforced polymeric component includes a web of reinforcing fibers wrapped around a plurality of pins. The web of reinforcing fibers includes a plurality of layers. The reinforced polymeric component further includes a molded and processed polymer containing the web of reinforcing fibers and pins.
