  • Publication number: 20090206504
    Abstract: A deformable sandwich panel is disclosed according to one embodiment. The deformable sandwich panel may include first and second face sheets. These face sheets may each comprise a first and second surface and be substantially flat. The deformable sandwich panel also includes a shape memory material sandwiched between the first face sheet and the second face sheet. The shape memory material may be in continuous contact with a substantial portion of the first surface of the first face sheet and with a substantial portion of the first surface of the second face sheet. The deformable sandwich panel may be fabricated with a first shape, deformed into a second shape and then deployed back to the first shape. The first and second shapes may be maintained without mechanical loads.

  • Publication number: 20070262204
    Abstract: A deployable structure is disclosed. The deployable structure may include one or more slit-tube longerons; and one or more flat sheets coupled with the one or more slit-tube longerons. The one or more slit-tube longerons and the one or more flat sheets may be stowed by rolling the one or more slit-tube longerons and the one or more flat sheets together into a roll. In one embodiment, at least a portion of the one or more slit-tube longerons may be exposed when stowed. In another embodiment, the one or more slit-tube longerons may be manufactured from a shape memory material. These slit-tube longerons unroll into to a straight configuration when exposed to heat.

  • Publication number: 20070199709
    Abstract: Methods are provided of producing a heater cable. An electrical conductor is coated with a preceramic resin. At least a portion of the coated electrical conductor is deployed into a operational location. The preceramic resin is pyrolyzed while the portion of the coated electrical conductor is in the operational location to convert the preceramic resin into a ceramic insulator disposed to electrically insulate the electrical conductor from the sheath.

  • Publication number: 20070181306
    Abstract: Methods are disclosed for producing an insulated electrical conductor. Electrically uninsulated portions of respective electrical conductors are connected. A joint between the electrically uninsulated portions is coated with a preceramic resin, which is heated to cure the preceramic resin into a green-state insulator that substantially covers the joint.

  • Patent number: 6407339
    Abstract: A high temperature electrical insulation is described, which is suitable for electrical windings for any number of applications. The inventive insulation comprises a cured preceramic polymer resin, which is preferably a polysiloxane resin. A method for insulating electrical windings, which are intended for use in high temperature environments, such as superconductors and the like, advantageously comprises the steps of, first, applying a preceramic polymer layer to a conductor core, to function as an insulation layer, and second, curing the preceramic polymer layer. The conductor core preferably comprises a metallic wire, which may be wound into a coil. In the preferred method, the applying step comprises a step of wrapping the conductor core with a sleeve or tape of glass or ceramic fabric which has been impregnated by a preceramic polymer resin.
