Glass fiber reinforced thermoplastic polyurethane (GF-TPU) combines TPU’s elasticity with the rigidity of short glass fibers, resulting in improved modulus, tensile strength, tear resistance, heat resistance, and dimensional stability while retaining flexibility. Research shows that fiber type, length, and content significantly influence dispersion, anisotropy, wear performance, and impact resistance. Optimal designs balance stiffness and toughness for specific applications. GF-TPU composites—processible by injection molding, extrusion, and calendering—are already used in automotive and industrial parts, with aramid fiber variants offering alternative reinforcement options.
