Carbon fiber structures having improved interlaminar properties

摘要: A carbon fiber structure suitable for use in high performance composites which is characterized by a primary having filaments grown therefrom, wherein substantially all of the are form selected from branched, spiral, helical, or combination thereof. The fibers an alloy catalyst comprises first metal Group IB Periodic Table Elements, and one more metals second group iron, nickel, cobalt, zinc; optionally third titanium, tungsten, tin tantalum.
