This document describes a manufacturing method for processing unidirectional carbon fiber/epoxy resin impregnated sheet and tape into multi-ply broadgoods and tape produced on an automated cross-plying machine. Broadgoods or tape of two or more ply configurations may be processed@ where ply orientations of 0??45??90??and 135??as examples) may be automatically layed in a programmed sequence. In all configurations@ the 0??ly direction is parallel to the length of the broadgoods roll or sheet@ or tape. Automated manufacture of continuous multi-ply product of two or more repetitive layers ensures wequential ply orientations at a reduction in manhour expenditure for hand layup of each ply.
