研究了在平纹机织碳纤维增强塑料（CF）/液体橡胶改性环氧树脂（端羧基液体丁二烯-丙烯腈- CTBN）复合材料中添加细菌纤维素（BC）对复合材料力学性能和热性能的影响。新的复合材料的特点是不同的技术，即拉伸，弯曲，动态力学分析（DMA），断裂韧性（模式I）测试和扫描电子显微镜。结果表明，当BC纤维含量为0.5%时，模型的起裂韧性和扩展韧性分别提高了84%和72%。在10%液体橡胶改性的复合材料中加入0 5%的BC，使复合材料在2 0 0 ℃下的储能模量提高了2 8%，表明BC和CTBN的组合有助于提高复合材料的耐热性。(C)2010爱思唯尔有限公司版权所有
This investigation concerns the manufacturing of a new type of composite with the goal of studying the effect of natural fiber on high performance composites Effect of adding bacterial cellulose (BC) as natural fiber to plain woven carbon fiber reinforced plastic (CF)/epoxy modified with liquid rubber (Carboxyl-Terminated Liquid Butadiene-Acrylonitnle - CTBN) on the mechanical properties and thermal properties has been investigated. New composite was characterized by different techniques, namely tensile, bending, dynamic mechanical analysis (DMA), fracture toughness (mode I) test and scanning electron microscope. The results reveal that at a BC fiber content of 0 5%, the initiation and propagation interlaminar fracture toughness in model improved by 84% and 72% respectively. Addition of 0 5% of BC to composite modified with 10% liquid rubber improved the storage modulus by 28% at 200 degrees C indicating that the combination of BC and CTBN contribute to improve the heat resistance of the composite.
