氧化石墨烯掺量下碳纤维复合材料层合板的电学性能测试氧化石墨烯掺量下碳纤维复合材料层合板的电学性能测试摘 要碳纤维复合材料（Carbon Fiber Reinforced Polymer/Plastic，简称 CFRP）被广泛应用于体育器械、航空航天、化工机械与纺织及医学等多个不同的领域得益于其优异的力学性能。因此，学者们多对 CFRP 进行的力学性能的研究，但 CFRP 的电学性能研究方面却鲜为人关注和涉足。本设计以掺入氧化石墨烯（graphene oxide，简称 GO）的环氧树脂基碳纤维复合材料层合板为研究对象，设计其电学性能的测试电路，推测其内部结构，预测其电学性能测试的结果，分析其导电机理。该样品材料的制作使用挤压的方法以环氧树脂为基底，粘合各层碳纤维布片。电导率测试电路采用单臂惠斯通电桥与反向比例运算电路串联设计而成。该实验设计可得到不同 GO 掺杂浓度的样品在不同温度下的电导率。推测结果表明：GO 的掺入浓度对环氧树脂基碳纤维层合板的各向的导电性能均有一定的影响，层合板样品的平均电导率随 GO 的掺入浓度的升高而变大；在未达到环氧树脂的熔融温度的温度范围内，该材料的导电性能基本不受温度的影响。北京理工大学珠海学院 2020 届本科生毕业设计关键词：碳纤维；环氧树脂；氧化石墨烯；掺杂浓度；电导率；复合材料Electrical performance test of carbon fiber composite laminates with graphene oxide contentAbstractCarbon fiber composites (carbon fiber reinforced polymer, abbreviated CFRP) are applied to many different fields, such as sporting instruments, aerospace, chemical machinery, spinning and medicine, but thanks to their excellent mechanical performance. Therefore, researchers often study the mechanical performance of CFRP, but in the field of research on the performance of CFRP, human interest and foot are put in.This design takes the epoxy resin-based carbon fiber composite with graphene oxide (GO) as the research object, designs the test circuit of its electrical performance, speculates its internal structure, predicts the test results of its electrical performance, and analyzes its conductive mechanism.
