Abstract
Abstract This invention is addressed to the improvement in the bonding relationship between inorganic and organic fibers with elastomeric materials in the manufacture of fiber reinforced elastomeric products wherein impregnated bundles of fibers are provided with at least a coating of a vulcanization retarder to moderate the rate of vulcanization of the elastomeric material with which the bundles of fibers are combined to eliminate an elastomer-elastomer interface heretofore formed to thereby further improve the bonding relationship established between the fiber bundles and the elastomeric material.
