“…13 These fibers have covered the para- and meta-aramid fibers, 14 polybenzobisoxazole (PBO) fiber, 15 polybenzimidazole fiber, 16 poly(hydroquinone-diimidazopyridine) fiber, 17 ultrahigh molecular weight polyethylene (UHMWPE) fiber, 18 and polytetrafluoroethylene fiber, 19 and some of them are now available as commercial products such as Kevlar ® , Nomex ® , Twaron ® , Zylon ® , Dyneema ® , Spectra ® , and Teflon ® . 20 –23 The excellent mechanical properties of these novel synthetic fibers make them competitive in engineering and structural applications for various forms of advanced composites with higher mechanical strength, better damage tolerance, higher load-bearing stiffness, more significant lightweight, and better thermal stability compared to the traditional inorganic fiber-reinforced composites. In a world where lightweight and durable composites are increasingly replacing conventional materials, the reinforcement of thermoplastics with high-performance organic fibers has been receiving a great deal of attention in both academic communities and industrial societies.…”
