Abstract
A method of making a fiber reinforced energetic composite is provided. The method includes providing a mold or mandrel defining a shape for the fiber reinforced energetic composite, providing an impregnated fiber layup over the mold or mandrel, and curing the impregnated fiber layup. The impregnated fiber layup includes a fiber layup and polymer resin, the fiber layup formed from a plurality of reinforcing fiber layers and an energetic polymer nanocomposite disposed adjacent one or more of the reinforcing fiber layers with the polymer resin impregnated within the reinforcing fiber layers. The energetic polymer nanocomposite includes core-shell nanoparticles entrained in a thermoplastic polymer matrix where the core-shell nanoparticles include a core made of metal and at least one shell layer made of metal oxide disposed on the core or a core made of metal oxide and at least one shell layer made of metal disposed on the core.
