Abstract: A permeable LSP material that can be incorporated into a resin infusion process such as RTM and VaRTM. This permeable LSP material may be in the form of an elongated or continuous tape that can be used in an automated placement process such as ATL and AFP. In one embodiment, the permeable LSP material includes at least the following components: (a) a nonwoven veil of randomly arranged fibers; (b) a porous electrically conductive layer having openings through its thickness; and (c) a resin material distributed, in a non-continuous manner, throughout the nonwoven veil 11 and between the nonwoven veil and the porous conductive layer. The permeable LSP material can be brought into contact with a dry preform, followed by resin infusion and curing to form a hardened composite part having the LSP material integrated therein.

Abstract: A curable composite material that may be used in applications where both high mechanical performance and high electrical conductivity are required. The curable composite material includes two or more layers of reinforcement fibers that have been infused or impregnated with a curable matrix resin and an interlaminar region containing carbon nanomaterials, e.g. carbon nanotubes, and insoluble polymeric toughening particles. The carbon nanomaterials are significantly smaller in size as compared to the polymeric toughening particles. The polymeric toughening particles are substantially insoluble in the matrix resin upon curing of the composite material, and remain as discreet particles at the interlaminar region after curing. Methods for fabricating curable composite materials and cured composite structures are also disclosed.

Abstract: A flexible, self-supporting hybrid veil that is permeable to liquid and gas. The hybrid veil includes: (a) intermingled, randomly arranged fibres in the form of a nonwoven structure; (b) particles dispersed throughout the nonwoven structure, wherein a majority of the particles are penetrating through the thickness of the nonwoven structure; and (c) a polymeric or resinous binder present throughout the veil. Such hybrid veil can be incorporated into composite laminates, prepregs, fabrics and fibrous preforms.

Abstract: A dry, fibrous tape for use in an automated placement process such as ATL or AFP and a preform produced therefrom. The preform is configured for resin infusion. The tape contains a layer of unidirectional fibers, at least one nonwoven veil bonded to one side of the fiber layer, and at least binding materials present within the tape. The preform produced from laying down such tape exhibits a low-bulk property that is close to the final thickness of the cured fiber-reinforced resin article and no further consolidation or compaction is required.
