Abstract The interfacial adhesion between fibers as reinforcing fillers and thermoplastic matrices is a key requirement for obtaining effective reinforcement. Therefore, in situ polymerization of styrene onto polyethyleneterephthalate and in situ bulk polymerization of the same monomer on aromatic polyamide (Kevlar-aramid) fibers were carried out. In both cases, divinyl benzene was used as crosslinking agent in order to ensure the presence of reasonable amount of covalently bonded and nonextractable polystyrene on and/or onto the fibers. This treatment enhances the interfacial adhesion of investigated fibers to polystyrene matrix. The fibers were located in the matrix in continuous and uniaxially aligned form using a new injection moulding technique. A relation between the per cent change in weight of treated polyethyleneterephthalate and relative increase in the tensile strength of corresponding treated fiber-polystyrene composites was established. Some factors affecting the interfacial adhesion between investigated fibers and polystyrene matrix were discussed.
