Fiber-reinforced polymer composites have attracted significant interest as structural materials in aerospace, automobile, railways, etc. due to their excellent mechanical and lightweight properties. Especially, polymer composites used as structural and electronic materials require not only excellent specific strength with long-term durability but also antistatic and electromagnetic interference. Carbon fibers(CFs), which have excellent modulus, strength, thermal and electrical performance, are regarded as ideal reinforcing filler materials for polymer matrix composites. Thermotropic liquid crystal polyester(TLCP) containing rigid aromatic rings between ester functional groups is known as a super engineering thermoplastic with outstanding mechanical modulus, chemical resistance, and thermal stability. In this study, we investigate the microstructure and physical properties of TLCP-based composites reinforced with polyester-coated CFs, which are fabricated by efficient melt-compounding. |
