  • Publication number: 20230251064
    Abstract: A net-shape ballistic panel is formed by a process of arranging a fiber bundle on a substrate to form a layer, the layer following a shape of the ballistic panel, securing the fiber bundle to the substrate with a plurality of stitches to form a preform layer, arranging additional layers of fiber bundles on the preform layer, each layer of the additional layers following the shape of the ballistic panel, and each fiber bundle being secured with a plurality of stitches to each layer of the additional layers to form a plurality of preform layers. A resin is then impregnated into the preform layers and subsequently cured using a process such as compression molding. The resulting ballistic panel is relatively thin while exhibiting an excellent ballistic rating (e.g., V50).

    Abstract: A composite aerogel material includes a carbonized aerogel defining a 3D porous structure and a silicon-based material dispersed within the 3D porous structure, wherein the silicon-based material includes at least 70% by mass fraction. A method of manufacturing a composite aerogel material includes mixing water, an acrylonitrile monomer, silicon particles, a surfactant, a thermal polymerization initiator, and a solvent and heating as a solution. The solution is quenched, wherein a polyacrylonitrile (PAN) silicon nanoparticle micro bead gel precipitates from the solution. A solvent exchange then occurs to form a silicon-based aerogel material, which is then freeze dried. The silicon-based aerogel material is carbonized to form a composite aerogel material comprising a carbonized aerogel defining a 3D porous structure and a silicon-based material dispersed within pores of the carbonized aerogel.
