ABSTRACT:
Carbon fibers subjected to an electrolytic treatment in an oxidizer bath followed by electrolytic treatment in an ammonium bath have surface elemental content of oxygen greater than 7% and nitrogen greater than 4%. Composites based on the carbon fiber in combination with bis-maleimide type matrix resins have improved toughness and interfacial bonding.
