Effect of carbon fiber surface microstructure on mechanical properties of CCF800

The surface microstructure of 10 samples of CCF800 carbon fibers was quantitatively characterized by the number, width, depth and distribution of grooves. With the help of self-programmed Matlab, the fractured cross-section SEM images were binarization processed and contour extracted, and then the linear equation tangent method was used to identify grooves and to measure width and depth of each groove. Using Weibull distribution equation, shape...
