Abstract
A composite prepreg yarn designed and constructed is a very large, strong yarn with resin infused throughout, which can be used to prepare composite preforms via conventional Maypole braiding or other textile processes. The invention increases the loads that can be transmitted by the cured yarn in a composite structure, decreases the stickiness that can prevent their use in braiding and other textile processes, provides protection to the high-strength fibers from abrasion that is encountered during and after composite preform manufacturing via braiding.
