Abstract
Composite materials comprised of reinforcing filaments captured in an uncured resinous matrix are shaped and subsequently stacked by a technique which may be automated. The composite material, in tape form, is sandwiched between liners, the liners being selected or treated so as to exhibit an adhesion differential with respect to the tacky uncured resin, and the plies of the resultant multilayer article are thereafter cut, the upper liner removed and the plies stacked utilizing the ply-to-ply adherence.
