An integrated, automated composite material manufacturing system for pre-cure processing of preimpregnated composite materials, and particularly, for one-sided preimpregnated composite materials. The system includes a computer control subsystem for controlling and synchronizing the pre-cure processing operations, a material cutting station for controlled cutting of preimpregnated composite materials into individual composite plies of predetermined size and shape based upon composite ply configurations stored in the computer control subsystem means, a ply unloading subsystem for providing automatic pickup, transfer and placement operations to unload the individual composite plies utilizing a multiplicity of bi-functional transfer feet that are automatically, selectively activated to form a predetermined combination operative to engage and retain and disengage and release the tacky surface of individual composite plies, a ply transfer subsystem automatically operative to transfer composite plies between the unloading subsystem and the ply inverting subsystem, a ply inverting subsystem for rotating individual composite plies to place the non-tacky surface up, a ply transfer/layup subsystem to transfer composite plies to a composite article mold having a mold surface and to layup the transferred composite plies on the mold surface, and a ply conforming subsystem for conforming said layed up composite plies with the mold surface.
