摘要：
Carbon fibers can be surface treated to improve interfacial bonding in a composition comprising said fibers reinforcing a bis-maleimide matrix resin, comprising the steps of:
moving said fiber, as anode, through a first aqueous electrolytic bath containing an ionized acid base or neutral salt, followed by
moving said fiber, as anode, through a second electrolytic bath containing an ammonium salt, said bath having a pH of at least about 8.
Composites comprising the carbon fibers so treated in a bis-maleimide matrix resin have good edge delamination strength.
