AUTOMATED MANUFACTURE OF CONTINUOUS MULTI-PLY GRAPHITE FIBER/EPOXY RESIN IMPREGNATED BROADGOODS

1980-10-01
HISTORICAL
ARP1674
This Aerospace Recommended Practice (ARP) describes a manufacturing method for processing unidirectional graphite 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.
