Abstract
The mechanochemical fabrication of the composites between carbon fibers (CFs) and nylon-6 (N6) was investigated using a milling process. By the milling, defected surfaces were generated on CFs to obtain the homogeneous length with preserving the cylindrical shape of CF. Fourier transform infrared spectra revealed that the band intensities due to C═O, C–N and O–H bondings increased with the milling. The band position of C–N was shifted to a higher wavenumber, while that of C═O did not change, implying that the main chain of N6 was dissociated at the C–N neighboring the C═O bonds by the force, and subsequently, new bonds between the N atoms of the activated N6 and the C atoms on CFs would be formed. Therefore, the efficient fabrication of the CF/N6 composite fibers with the interfacial bondings was achieved using the mechanochemical reaction.
