Abstract
A kinetic energy absorptive composite article includes a first ply and a plurality of inherently straight first fibers contained in the first ply. First length portions of the first fibers are arranged with first localized ripples that deviate from and return to individual first routes of respective first length portions. The article includes a second ply parallel to the first ply, a plurality of inherently straight second fibers contained in the first ply or the second ply, and a matrix material at least partially encapsulating the first and second plies. Second length portions of the second fibers are arranged without localized ripples or with second localized ripples that deviate from individual second routes of respective second length portions to a lesser extent than the first localized ripples and return to the individual second routes. The second routes are substantially parallel to the first routes.
