On the Structure and Dissolution Properties of Poly(p-phenylene terephthalamide): Effect of Solvent CompositionPoly-p-phenylenetherephthalamide (PpPTA) is a high performance, semi flexible polymer. Commercially it is mainly sold in the... HP Westerhof - 《Applied Sciences》 被引量: 2发表: 20...
In addition, the single fiber tensile tests were also conducted for the PPODTA fibers, and the relation between the tensile properties and the fatigue resistance of the PPODTA fiber was investigated. The fatigue resistance of the PPODTA fiber was increased with the decrease of the fiber diameter...
PURPOSE:To obtain a poly-para-phenylene terephthalamide (PPTA) film, which shows excellent mechanical characteristic both in longitudinal direction (machine direction) and in width direction (transverse direction), by a simple means wherein transparent and excellent areal orienting properties are obtaine...
In order to increase the use temperature and mechanical properties of PBO paper based composite, advanced composite material using polyimide as reinforcing resin has been studied. 聚对苯撑苯并二噁唑(PBO)因其分子链刚性结构以及纤维表面化学惰性导致其力学性能较差,即使通过环氧树脂增强,其综合性能仍然不能...
