Abstract： The tensile strength of Toray T800HB-600 polyacrylonitrile （Pan）-based carbon fiber monofilament is tested according to GB/T31290-2014. The load-elongation curves of monofilament are analyzed to obtain the system compliance “K”. The elastic modulus of tension is calculated with the experimental system flexibility “K”， which is close to the reference value given by Toray.

Keywords： carbon fiber， tensile strength， gauge， load-elongation curve， system compliance， tensile modulus
