Abstract:
A coating of a viscous lubricant applied prior to stretch-breaking permits forming slivers of stretch-broken carbon fibers. When an anti-static ingredient is added to the viscous lubricant cohesive slivers of stretch-broken glass fibers can be formed. Composites of matrix resin reinforced with these slivers exhibit high strength, tensile stiffness, and good formability.
