“…The difference in the stress–strain curves among the high‐performance polymeric fibers strongly depends on the crystallinity and preferential orientation of the fibril structures, although the absolute tensile modulus and strengths of the fibers depend on the character of materials (molecular structures, weights, etc.). For the highly crystallinity and oriented fibril structures of the PBO (ZylonAS, ZylonHM) and the PPTA (Kevlar49) fibers,20 which is observed in the tensile modulus of fibers, the stress–strain curve shows almost linear behavior. For the highly crystallinity and slightly curved fibril structures of the PPTA (Kevlar29, Kevlar119, Kevlar129, Twaron), PPODTA (Technora), and PAR (VectranHT, VectranUM) fibers, the stress–strain curve shows almost linear behavior in the initial stage of loading.…”

The tensile properties and fracture behavior of poly-(para-phenylene-2,6-benzobisoxazole), poly-(para-phenylene terephthalamide), co-poly-(para-phenylene-3,4 0 -oxydiphenylene terephthalamide), polyarylate, polyethylene, and poly(lactic acid) highperformance polymeric fibers have been investigated. The Weibull statistical distributions of the tensile strength were also characterized. The results clearly show that for various types of high-performance polymer fibers, the Weibull modulus decreases with an increase in the tensile modulus, the tensile strength, and inverse of the failure strain.

“…Nowadays, the mechanical properties of PI fibers need to be further improved to meet the application requirement in advanced composites and structural materials . The tensile strength and modulus of PI fibers strongly depend on the intermolecular interaction, chain rigidity, macrostructures (orientation and crystallinity) as well as morphology, which is no doubt affected by chemical composition, the way of production and processing conditions.…”

High strength and high modulus polyimide (HSHMPI) fibers are a type of novel high-performance organic fiber with an initial modulus higher than 90 GPa and extremely high tensile strength over 2.5 GPa realizing broad applications in the fields of electronic, engineering, aerospace, and atomic energy industries. There are currently two synthetic pathways, i.e., one-step and two-step methods, developed for the manufacture of HSHMPI fibers. An integrated fabrication process involving wet-spinning followed by thermal imidization is accepted as a typical two-step synthetic route for industrialization of HSHMPI fibers. In this article, the classification, synthetic method and technology, molecular structure, morphology, microstructures, and properties of HSHMPI fibers are summarized extensively. The effects of molecular structure and synthetic technology on the microstructures and overall performance of HSHMPI fibers are discussed. In addition, the trend in development and the application prospect of HSHMPI fibers are analyzed accordingly.

“…High‐performance fibers have exhibited an enabling technology for so many present and future high‐technology products. In recent years, significant progress has been made on high performance fibers that are produced from rigid and flexible polymers, such as Zylon, Kevlar, Dyneema, M5, and Carbon fibers . The mechanical properties of the novel synthetic fibers make them competitive in most applications in light and slender advanced composite components and structures.…”

Co‐polyimide (co‐PI) fibers with outstanding mechanical properties were fabricated via thermal imidization of polyamic acids, derived from a new design of combining the amide and benzimidazole diamine monomers, 4‐amino‐N‐(4‐aminophenyl)benzamide (DABA) and 2‐(4‐aminophenyl)‐5‐aminobenzimidazole (BIA), with 3,3′,4,4′‐biphenyltetracarboxylic dianhydride (BPDA). The crystalline structure and micromorphology of the prepared co‐PI fibers were investigated by synchrotron wide‐angle X‐ray diffraction (WAXD) and small‐angle X‐ray scattering (SAXS). The two‐dimensional WAXD spectra imply that the co‐PI fibers possess a structure between smectic‐like and three‐dimensionally ordered crystalline phase, and all the obtained fibers are highly oriented along the fiber axis. SAXS patterns exhibit a pair of meridional scattering streaks for the homo‐PI (BPDA/BIA) fiber, suggesting the presence of periodic lamellar structure. The incorporation of DABA into the polymer chains destroyed the lamellar structure but led to smaller size of microvoids upon increasing DABA moiety, based on SAXS analysis. The co‐PI fibers, with the molar ratio of BIA/DABA being 7/3, exhibited the optimum tensile strength and modulus of 1.96 and 108.3 GPa, respectively, attributed to the well‐defined ordered and dense structure. The chemical structure and molecular packing significantly affected the thermal stability of fibers, resulting in the different glass transition temperatures (Tg) from 350 to 380 °C. © 2014 Wiley Periodicals, Inc.
