  • Patent number: 11999834
    Abstract: A precursor composition comprising, before cure, an acrylic ethylene monomer (AEM), a foaming agent, and one or more of a strengthening additive, a thermal ablation additive, or a reflectivity additive. The precursor composition is cured to form a protective article comprising a foamed protective material. A method of forming a protective article is also disclosed, as is an aerospace structure comprising the foamed protective material.
    Type: Grant

  • Patent number: 11077627
    Abstract: A protective assembly comprises a first region formulated and configured to provide protection from alpha, beta, and electromagnetic radiation and comprising a composite of particles and polymer; a second region formulated and configured to provide protection from ballistic impact and comprising a composite of fibers and polymer; and a third region formulated and configured to provide protection from thermal radiation and comprising a composite of particles, fiber, and polymer. The protective assembly may be provided on an aerospace structure. The protective assembly may be formed on the aerospace structure body using a co-curing process.

  • Patent number: 8936810
    Abstract: Rapid and accurate determination of the formulation orientation of multi-layer capsule-shaped tablets with respect to different internal formulation layers proximate to the opposite narrow and rounded ends of the tablets is required. By including an appropriate color scheme in multi-layer osmotic tablets, detection of the formulation orientation is achieved by detecting the color at a spot location on a side of the tablet corresponding to one or another formulation layer or to one or another interface of two formulation layers depending on the formulation orientation of the tablet.

  • Patent number: 5425973
    Abstract: An integral overwrap protective system for a vehicle, e.g., a missile. Includes a filament wound fiber reinforced rubber matrix over a fiber-reinforced composite laminate which forms the vehicle inner skin and a final elastomeric outer coating. The integral overwrap avoids the bonding between vehicle skin and the protective system as in the present systems.
