Abstract:

The surface characteristics of various carbon and graphite fibers and the interfacial region between fibers and resin in composites were investigated by using microscopy, electron dif-fraction and Raman spectroscopy. Graphite fiber composites were prepared by in situ polymerization on mylon 6. Orientated cry- stallization of the monomers of nylon 6 and and nylon 66 on graphite fibers and subsequent solid state reaction yielded dimers and trimers, respectively, instead of the usual polymers, thus showing a strong and specific effect of surface interactions.
