The surfaces of high-modulus poly ( p-phenylene-2, 6-benzobisoxazole) (HMPBO) fibres have been treated by a solution polyphosphoric acid/acetic acid (PPA/AA). single fibre pull-out strength, chemical compositions and surface morphologies HMPBO were tested characterized tests, contact angles, X-ray photoelectron spectroscopy, atomic force microscope, scanning electron microscopy thermogravimetric analyzer. Results show that this method has great potential in the treatment fibres.
