    摘要: Provided are methods of forming thermally conductive flexible bonds for use in electronic boards of unmanned spacecraft and other types of aircraft. Also provided are methods of preparing adhesive materials to form these bonds including methods of preparing treated filler particles. In some aspects, an adhesive material includes filler particles having organofunctional groups, such as boron nitride particles treated in silane. These particles may be combined with a urethane modified epoxy to form the adhesive material. The weight ratio of the particles in the adhesive material may be about 40-60%. The adhesive material may be thermally cured using a temperature of less than 110° C. to prevent damage to bonded electronic components. The cured adhesive may have a thermal conductivity of at least about 2 W/m K measured in vacuum and may have a glass transition temperature if less than −40° C.

    摘要: A thermal control tape for providing thermal control of a spacecraft structure, to which the thermal control tape is applied is provided. The thermal control tape has a filled silicone resin layer having a first side and a second side. The filled silicone resin layer has a silicone resin material filled with a white inorganic filler material. The tape further has a silicone pressure sensitive adhesive (PSA) layer having a first side and a second side, the first side of the silicone PSA layer attached to the second side of the filled silicone resin layer. The filled silicone resin layer and the silicone PSA layer form the thermal control tape, with the second side of the silicone PSA layer configured for attachment to at least one surface of the spacecraft structure of a spacecraft, to provide thermal control of the spacecraft structure, by radiating heat away from the spacecraft structure.
