  • Patent number: 11930565
    Abstract: The present invention is an apparatus for curing composites out-of-autoclave and out-of-oven. The apparatus is a multilayered composite tool for shaping and curing composites. It also contains a sealant layer and composite resistive heating element on the tool's surface. This heating element provides heat to the composites during cure while binding it to the other layers, eliminating the need for external heat from autoclave and oven sources. A ceramic layer is applied to the top surface of the resistive heater for electrical insulation, heater protection and to provide a smooth surface for finish for the composite components being processed with the invention. A method for using the invention is also described. Finally, one embodiment of the invention is presented where a negative composite tool is created to apply additional pressure to the composite component during curing. This additional pressure enables the current invention to more closely mimic autoclave composite processing.

  • Patent number: 11623866
    Abstract: A method encapsulates nanoscale material by producing a suspension of the nanostructure material in a first solvent using a micelle surrounding the nanostructure material. The micelle surrounding the suspended nanostructure material is swollen by adding to and mixing with the suspension an immiscible phase second solvent containing a precursor. The precursor is then reduced by adding a reducing reactant selectively soluble in the first solvent that reacts to the precursor containing reactant selectively solvated in the second solvent to encapsulate the nanostructure material. A metal-nanostructure composite can be provided by collecting and mixing the metal-shell encapsulated nanostructure product produced by the aforementioned method into a metal matrix.
