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 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 thermoset resin composition and composite materials containing reinforcement fibers impregnated with the thermoset resin composition. The thermoset resin composition contains: (a) a combination of multifunctional epoxy resins; (b) 4,4′-meth-ylenebis(2,6-xylidine) as a curative for the epoxy resins; and (c) a thermoplastic component, wherein the thermoset resin composition is void of any catalyst or accelerator that is reactive with the epoxy resins.

Abstract: A fire retardant veil (10) composed of intermingled, randomly arranged fibres and fire retardant particles (11) dispersed throughout the nonwoven structure of the veil (10). The veil (10) further includes a small amount of a polymeric or resinous binder for binding the fibres and the particles together. Such fire retardant veil (10) can be incorporated into composite laminates, prepregs, and fibrous preforms (12) configured for liquid resin infusion.
