In this work, the effects of maleic anhydride (MA) content on mechanical properties of
chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites.
A direct oxyfluorination on CF surfaces was applied to increase the interfacial
strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP
composites are likely to be different in terms of MA content. Surface characteristics were
observed by scanning electron microscope, Fourier transform infrared spectroscopy, and
single fiber contact angle method. The mechanical properties of the composites were also
measured by a critical stress intensity factor (KIC). From the KIC test results, the KIC values
were increased to a maximum value of 3.4 MPa with the 0.1 % of MA in the PP, and then
decreased with higher MA content.
