Investigation of fiber slippage in the chopping process of carbon fiber tows under rigid support

As an important application form of carbon fiber (CF), short CFs and their production process have self-evident research value. In this work, the chopping process of CF tows under rigid support and the essential cause of high cutting forces were explored. Large-tow CFs containing 1–3000 single filaments were chopped, and the fracture processes were observed and described. It was found that obvious fiber slippage phenomena and intermediate...
