AN INVESTIGATION OF GLASS REINFORCEMENT EFFECTS ON THERMOPLASTIC POLYURETHANE

摘要

The significance of glass reinforced thermoplastic polyurethane (TPU) to the plastics industry is the potential to provide the beneficial properties of TPU with improved tensile strength and modulus, without sacrificing a substantial amount of impact strength. This paper presents a study of the addition of glass to TPU. It includes the evaluation of two different base resins with two different milled fibers. The research will be focused primarily on floccular milled fibers with various compatibilizers (sizings) such as untreated, cationic, and silane added to a polyester and a polyester based TPU. Each type of coated fiber will be run at different percentages to determine the optimum sizing/resin comparability.
