Abstract

The surface properties of a high modulus unsized carbon fiber modified by treatment with aq. ammonia were studied. Base groups were detected by potentiometric titrn. in addn. to the pristine acid groups in untreated fiber. The surface compn. of carbon fibers modified with maleic anhydride, isophorone diamine, or tetracyanoethylene was detd. by XPS anal. The interactions of modified carbon fibers with DGEBA epoxy resin (Epikote 828) were studied using the single fiber composite test method. The ammonia treated carbon fibers showed improvements on fiber/matrix stress transfer
