摘要
炭纤维制成极细的粉粒后,其微粒的表面结构与表面特性将有显著的改变,导电性能也与长丝略有不同。为讨论粉体电阻率的变化,本文介绍一种测量CF粉体电阻率的实验方法,从电阻率与压力的关系曲线上, 可估测出最小电阻率及压力最佳取值范围。
When carbon fibre is made into fine powder, its surface structure and property will change remarkably, of which the electrical conductivity is also slightly different from the long thread. In this paper an experimental method of measuring the electrical resistivity of CF powder is introduced. It has demonstrated that the optimum sampling scope of measuring the min- inum resistivity and pressure is estimated from the curve of the relationship between the electrical resistivity and pressure.
