SAE ARP1674A

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~ ply 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 sequential ply orientations at a reduction in manhour expenditure for hand layup of each ply.
