In the polypropylene (PP)/carbon fiber (CF) composite, it has been well known that maleic acid modified PP (MAPP) improves the interfacial adhesion with CF. However, the effect of maleic acid modification on the PP crystals around CF, and that of the PP crystals on the interfacial adhesion have not been clarified well. In this study, the local crystal structure of PP near CF was investigated using micro-Raman spectroscopy, and it was demonstrated that the crystal growth of PP near CF contributes significantly to the interfacial adhesion.
