  • Flexible diaphragm-extreme temperature usage
    Patent number: 4989497
    Abstract: A diaphragm (10) suitable for extreme temperature usage, such as encountered in critical aerospace applications, is fabricated by a unique method, and of a unique combination of materials, which include multi-layered lay-ups of diaphragm materials (20a, 22, 20b) sandwiched between layers of bleeder fabric (29, 36), which, after being formed in the desired shape on a mold (26), are vacuum sealed (38) and then cured under pressure, in a heated autoclave, to produce a bond capable of withstanding extreme temperatures.
    Type: Grant
    Filed: April 23, 1987
    Date of Patent: February 5, 1991
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
