The GB/T32993-2016 standard specifies the measurement method of the volume resistivity of carbon fiber. It clarifies the applicable carbon fiber type, describes the measurement method based on specific principles, and details the required equipment, sample preparation process and test steps. According to this standard, the volume resistivity of carbon fiber can be accurately measured, which provides a key basis for the mass evaluation of carbon fiber and the rational application in aerospace, sporting goods and other fields, and strongly promotes the development of the carbon fiber industry and the mass improvement of products.
