Systems and methods are disclosed herein for a pressure tolerant energy system. The pressure tolerant energy system may comprise a pressure tolerant cavity and an energy system enclosed in the pressure tolerant cavity configured to provide electrical power to the vehicle. The energy system may include one or more battery cells and a pressure tolerant, programmable management circuit. The pressure tolerant cavity may be filled with an electrically-inert liquid, such as mineral oil. In some embodiments, the electrically-inert liquid may be kept at a positive pressure relative to a pressure external to the pressure tolerant cavity. The energy system may further comprise a pressure venting system configured to maintain the pressure inside the pressure tolerant cavity within a range of pressures. The pressure tolerant cavity may be sealed to prevent water ingress.

A method of manufacturing a composite insert includes forming a polymer mold from a polymer sheet which may have a glass transition temperature of 70 to 160? C., the polymer mold either includes a cavity or may form a cavity disposed between the polymer mold and the carrier. The method proceeds by depositing a liquid reactive composite insert composition, which may be a two-component composition including a first part comprised of an isocyanate-epoxy blend and a second part comprised of an alcohol-epoxy blend, into the cavity under low pressure conditions of 0-10 bar and low temperature conditions of 15-100? C. The composition is then allowed to become dimensionally stable either within the polymer mold or between the polymer mold and the carrier.

A system and method for primarily erecting curvilinear buildings using a plurality of interconnected structural tubes/sandwich panels is provided. Fabricating structural tubing comprises: connecting a fibrous and flexible lining to an inner surface of a flexible outer membrane, wherein the lining is saturated in a curable material that forms into a solid foam material when cured; and curing the curable material. Fabricating a sandwich panel comprises: connecting a first fibrous and flexible lining to an inner surface of a first flexible outer membrane, wherein the first lining is saturated in a curable material that forms into a solid foam when cured; connecting a second fibrous and flexible lining to an inner surface of a second flexible outer membrane, wherein the second lining is saturated in a curable material that forms into a solid foam when cured; and curing the curable material of the first lining and second linings.

A formulation includes a polymeric material, a nucleating agent, a blowing, and a surface active agent. The formulation can be used to form a container.

Nanoporous three-dimensional networks of polyurethane particles, e.g., polyurethane aerogels, and methods of preparation are presented herein. Such nanoporous networks may include polyurethane particles made up of linked polyisocyanate and polyol monomers. In some cases, greater than about 95% of the linkages between the polyisocyanate monomers and the polyol monomers are urethane linkages. To prepare such networks, a mixture including polyisocyanate monomers (e.g., diisocyanates, triisocyanates), polyol monomers (diols, triols), and a solvent is provided. The polyisocyanate and polyol monomers may be aliphatic or aromatic. A polyurethane catalyst is added to the mixture causing formation of linkages between the polyisocyanate monomers and the polyol monomers. Phase separation of particles from the reaction medium can be controlled to enable formation of polyurethane networks with desirable nanomorphologies, specific surface area, and mechanical properties. Various properties of such networks of polyurethane particles (e.g., strength, stiffness, flexibility, thermal conductivity) may be tailored depending on which monomers are provided in the reaction.
