    摘要: A flexible mosaic armor system that defeats threats at any attack angle includes top and middle solid elements layers separated by uniform gaps that intersect at apexes. The top elements can have a “hem” shape with raised edges. The middle elements can be flat, or can also have a hem shape. In embodiments, the edges of the top and middle layers are aligned and separated by an offset that is three or four times the gap width. Off-axis spike and needle strikes are thereby trapped between the two solid element layers, without added textile reinforcement. Embodiments include an apex layer of solid elements that overlap the first layer apexes, the apex layer being the second layer or a third layer beneath the 2 upper layers. The apex layer can be sandwiched between two textile backer layers that provide a full uninterrupted bonding surface to all of the solid element layers.

    摘要: A method for the encapsulation and triggered-release of water-soluble or water-dispersible materials. The method comprises a) providing an amount of electrolyte having a charge, b) providing an amount of counterion having a valence of at least 2, c) combining the polyelectrolyte and the counterion in a solution such that the polyelectrolyte self-assembles to form aggregates, d) adding a compound to be encapsulated, and e) adding nanoparticles to the solution such that nanoparticles arrange themselves around the aggregates. Release of the encapsulated species is triggered by disassembly or deformation of the microcapsules though disruption of the charge interactions. This method is specifically useful for the controlled viscosity reduction of the fracturing fluids commonly utilized in the oil field.
