Multifractal spectrum is used to characterize the surface morphology of carbon fiber reinforced plastic (CFRP). The surface morphology is measured by TalyScan 150, and multifractal spectrum is calculated by wavelet transform method. The results indicate that the multifractal spectrum is related to 3D surfaces morphology of CFRP, the range of Lipschitz exponent reflects the surface roughness, and value of the multifractal spectrum reflects the distribution of the peaks and valleys on the surface. Compared with the custom roughness evaluation, multifractal spectrum can evaluate the local morphology characteristics of surface morphology. [ABSTRACT FROM AUTHOR]
