    Abstract: A method for shaping dry preform material prior to resin infusion is disclosed. The starting material to be shaped is a preform blank (e.g. flat sheet) of dry, fibrous material. The shaping process is a vacuum forming process that relies on controlling the vacuum pressure and deformation speed to produce a shaped preform with three-dimensional configuration. The purpose of the shaping process described herein is to enable an automated process to replace the conventional hand lay-up operation.

    Abstract: Disclosed herein are devices and methods for manufacturing uncured, near-net shape plies. Such devices include: a plurality of spools, each dispensing a dry tow; optionally, a plurality of spreaders to spread the dry tows; optionally, a means to combine the dry tows into a plurality of tapes or bundles; a plurality of feeders, each carrying a tow, tape or bundle, and adapted to maintain the tows, tapes or bundles in a parallel arrangement; a cutting apparatus adapted to independently cut each individual tow, tape or bundle to a pre-determined length; optionally, a conveyor adapted to transport the cut tows, tapes or bundles away from the cutting apparatus; an in-line resin infuser adapted to impregnate the dry tows, tapes or bundles with resin material; and a receiver for the cut tows, tapes or bundles, wherein the cut tows, tapes or bundles are impregnated and configured in the form of a near-net shape ply.

    Abstract: A hybrid, woven textile material that can be used in the manufacturing of fiber-reinforced composite materials. The hybrid textile material is a woven fabric composed of unidirectional fibers interlaced with strips of non-woven fibers in a weaving pattern. In an embodiment, the hybrid textile material is porous or permeable with respect to liquid resins used in Resin Transfer Molding (RTM) processes and a preform formed from this textile material can be infused with liquid resins during such RTM processes.
