PULTRUSION SYSTEM WITH COOLING STAGE AND METHOD THEREFOR

A system for pultruding a beam comprises a pulling mechanism continuously pulling on a preform of yarns including a thermoplastic matrix and fibers, the pulling mechanism being downstream of the system. A pultrusion die has a tapering channel portion heated such that the preform is at a desired low viscosity temperature for resin in the thermoplastic matrix to impregnate the fibers. A cooling tube is at a downstream end of the pultrusion die. A cooling module is spaced from the pultrusion die by the cooling tube, the cooling module to cool the cooling tube before the preform reaches the pulling mechanism, wherein the cooling tube defines a cooling channel. A pultrusion mandrel may be present.

11358347 · 2022-06-14 · ·

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.
