It is shown that in-situ polymerization of monomers in the presence of functionalized carbon fibers leads to strong attachment of liquid crystal polymer chains on the fiber surface. This strong attachment most likely involves covalent grafting of chain ends on the surface. Evidence for the presence of the grafted chains was obtained from X-ray photoelectron spectroscopy and SEM analyses. Fracture surface analysis by SEM also reveals adhesion between grafted fibers and the matrix polymer and poor wetting of the same matrix on untreated carbon fibers. Organization of graded chains into a high density interfacial zone with significant backbone orientation is a possible surface state after the grafting preparation.
