ABSTRACT:
A method of mechanically converting unbranched fibers into highly branched or "fibrillated" fibers which are especially suitable for reinforcing composite materials such as brake linings. Unbranched starting fibers, immersed in water, are subjected to prolonged working in an intensive mixer or chopper having a very rapidly spinning blade with sharp knife edges, until extensive fiber branching occurs. Fibrillation can be achieved by this method even though conventional fiber "refining" techniques have no significant effect on the same starting material.
