A Review on the Study of Fiber-Reinforced Thermoplastic Elastomer Composites

Abstract

Fiber-reinforced elastomers can significantly enhance mechanical strength while retaining material softness, thereby expanding the application scope of elastomeric materials in scenarios requiring both high flexibility and high strength. Compared with thermoplastic polymers and ceramic materials, elastomers exhibit low modulus and high fracture strain, which result in more complex fiber–matrix interfacial behaviors. This review systematically elucidates the intrinsic relationships between microscopic stress transfer mechanisms and macroscopic mechanical properties in fiber-reinforced elastomers, summarizes research progress in this field over the past two decades, and highlights the effects of various reinforcement strategies on performance optimization, providing a theoretical basis for the design and development of next-generation high-performance fiber-reinforced elastomers.
