Study on Manufacturing PCT/PPS Flame Retardant Fiber by Sheath/Core Conjugate Spinning
Autor: Yong Wan Park, Hwan Chul Kim, Jong Cheol Lim
Publikováno v: Fibers and Polymers. 21:498-504
In this study, fiber for wigs was produced by a sheath/core conjugate spinning machine using poly PCT (cyclohexanedimethanol terephthalate) as a sheath polymer and PPS (polyphenylene sulfide) as a core polymer. In order to withstand the high temperat

Publikováno v: Journal of Industrial and Engineering Chemistry. 58:349-356
Optimization of the stabilization process for manufacturing low-cost carbon fibers was performed. By simply varying both heating rate (0.5–10 °C/min) and starting temperature (25–230 °C), the resulting fibers possessed different properties such

Mechanical properties enhanced by solid-state coupling reaction for molecular covalent bridges of carbon nanotube fibers
Autor: Hungo Choo, Ok-Kyung Park, Bon-Cheol Ku, Youngjin Jeong, Hyunju Kim, Hwan Chul Kim, Nam-Ho You, Jae Kwan Lee
Publikováno v: Materials Letters. 211:243-246
Carbon nanotubes (CNTs) exhibit outstanding mechanical and electrical properties. However, CNT fibers (CNTFs) have still problems in realizing these properties because of the weak forces between nanotubes with many defects of individual CNTs. Here, w

Evaluating the stabilization of isotropic pitch fibers for optimal tensile properties of carbon fibers
Autor: So Young Jang, Han-Ik Joh, Jisu Choi, Young Pyo Jeon, Namkyu Kang, Seunghyun Ko, Hwan Chul Kim, Sungho Lee
Publikováno v: Journal of Industrial and Engineering Chemistry. 45:316-322
The stabilization effects of isotropic pitch fibers on the tensile properties of the resulting carbon fibers were systematically studied to develop a simple method for finding a suitable degree of stabilization. As the stabilization temperature (250
