Abstract: A multifunctional surfacing material capable of providing lightning strike protection (LSP) and burn-through resistance. In one embodiment, the multifunctional surfacing material is composed of a conductive layer positioned between two resin layers, at least one of which contains one or more fire retardant compounds. In another embodiment, the multifunctional surfacing material is composed of a conductive layer positioned between two resin layers one of which is a thermally-stable layer. The surfacing material is co-curable with a composite substrate, e.g. prepreg or prepreg layup, which contains fiber-reinforced matrix resin.

Abstract: A sulfur reaction product formed by reacting elemental sulfur with an amine or epoxy compound containing reactive functionality. Such reaction product can be incorporated into a thermosettable resin composition as a modifier. When the thermosettable composition containing such sulfur reaction product is cured, the resulting crosslinked thermoset displays improved stress relaxation characteristics in line with vitrimer like behaviors.

Abstract: A resin infusion method that incorporates a melt-on-demand approach. The method includes: (a) providing a curable resin composition in the form of a block of frozen resin (20); (b) coupling the block of frozen resin (20) to an inlet port of a heated extruder (22), which comprises at least one rotating screw (24) housed within a heated barrel (25); (c) progressively melting the block of frozen resin (20) at the inlet port and concurrently feeding the melt resin through the heated barrel (25) to produce a liquid resin having a viscosity suitable for resin infusion; (d) continuously feeding the liquid resin exiting from the extruder to a mold, which contains a fibrous preform; and (e) introducing the liquid resin into the fibrous preform, wherein the block of frozen resin (20) provides an amount of resin composition sufficient for infusing the entire fibrous preform.
