Study on Interfacial Strength Properties between PBO Fiber Modified
1 緒 言 PBO(ポリパラフェニレンベンゾビスオキサゾ-ル) 繊維は,繊維強化複合材料の有機系強化繊維の一つであ り,炭素繊維に匹敵する強度・弾性率を有し,有機繊維 中最高の耐熱性・難燃性を示す事から,FRPの次世代の 強化繊維としての用途展開が期待されている.1), 2) しかしながら,PBO繊維は,繊維/樹脂間の界面強度 が不十分であり,この界面強度は FRPの様々な力学的特 性に大きく影響するため,3)PBO繊維の FRPの強化繊維と しての優れた特性を最大限に活かすためには,界面強度 向上を目的とした繊維表面改質法の研究が不可欠となっ てくる. 現在,繊維/樹脂間の界面強度の向上を目的として, 様々な表面改質法が試みられている.中でも低温プラズ マ処理は,ドライプロセスで低公害であり,繊維自身の 物性を損なうことなく,親水性の官能基を表面に効率的 に付与できるといった利点を...
متن کاملA Facile Route to Synthesize Nanographene Reinforced PBO Composites Fiber via in Situ Polymerization
The polymer matrix with introduced carbon-based nanofiber displays fascinating properties. They have inspired extensive research on the synthesis of polymer composites, which have been applied in catalysis, electronics, and energy storage. In this report, we reported a facile and efficient method to prepare poly(p-phenylene benzobisoxazole) (PBO)/nanographene (PNG) composites fibers via in-situ...
متن کاملDistributed Fiber Optic Sensing for a Full-scale PC Girder Strengthened with Prestressed PBO Sheets
Fiber Reinforcement Polymer(FRP) has been widely accepted as an innovative material for renovation and strengthening of existing infrastructures. Among the FRP materials, the Poly-p-phenylene benzobisoxazole (PBO) fiber sheets attracted great attention in recent years because of the high strength, high Young modulus and high energy absorption capability. In this study, a PBO Prestressing Upgrad...
متن کاملPBO based Enhancement of DSRC for VANET’s Safety Application
VANETs are a form of mobile ad-hoc networks to provide communications among nearby vehicles and between vehicles and nearby fixed equipment. Safety applications like collision alert merge assistance, road condition warning, etc requires messages to be propagated from the point of occurrence to the target vehicles with very low latency. DSRC is a two-way short-to-medium range wireless communicat...
