Composites of stretch broken aligned fibers of carbon and glass reinforced resin

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.

between steps of 6%, corresponding to Table I, as a future general yarn number series; and (2) conversion tables for the individual types of yarn, which include as corresponding values for the old numbers only the numerical values of Table I in the weight numbering system, then we could strive for another international decision which would lead to a gradual introduction of the standard weight numbering. It should be recommended that spinners, while continuing to use their old numbers, should give the equivalent value of the new weight numbering system in parentheses, numbers which can be taken from the internationally adopted conversion tables. A cotton yarn with the English number 20 would be designated &dquo;20 (tex 30)&dquo;; a linen yarn with the English number 55 as &dquo;55 (tex 30)&dquo;; a cotton or linen yarn with the metric number 34 would be designated with the number &dquo;34 (tex 30).&dquo; This additional information would greatly facilitate the use of the new yarn numbers by the yarn consumer, since, by one glance at the information in parentheses
