具有导电铺层的碳纤维复合材料直流体电阻测量方法
Testing Method for DC Volume Resistance of Carbon Fiber Reinforced Polymer with Conductive Material Layers
摘要
Abstract
We established a DC resistance test platform to study the test method for static electric properties and DC volume resistance of carbon fiber reinforced polymer (CFRP),which is widely used in aerospace industries.It is found that the testing results of CFRP volume resistance obtained from classical three-electrode test method of solid dielectric materials are quite different with the typical resistance of CFRP.So an improved three-electrode testing method was put forward and was used to investigate the DC volume resistance characteristics of CFRP.The experimental results show that the resistivity of CFRP is in the order of 108 Ω·m,which is between the resistivity of insulators and conductors.The volume resistance characteristics of CFRP are closely related with the internal layer structure,the surface coating materials,and the inner conductive materials of CFRP.The results can be well explained by the inferred conduction model,in which the comprehensive effect of electric field extension and surface current effect are considered.The research provides a theoretical support for further researches of electric characteristics,thermal degradation and weight loss of CFRP,and it also lays a solid foundation for its wide applications in aerospace industries.关键词
