A -- SIC/A1 METAL MATRIX COMPOSITE SPACE WAVEGUIDES SOL N00167-95-R-4015 DUE 080795 POC Ms. Kim Tatum, Contract Specialist (301) 394-3782/Contracting Officer, Pamela K. Collins or Renee Cairo-Iocco. The Carderock Division, White Oak Site, Naval Surface Warfare Center has a sole source requirement for six SiC/A1 metal matrix composite waveguides that meet the requirements of the High Gain Antenna Replacement Assembly for the Hubble Space Telescope project. The SiC/A1 composite material must be space qualified and must have reproducible material properties. The space telescope project requirements include high stiffness and strength, good thermal conductivity and limited coefficient of thermal expansion. Each waveguide is to be of an extruded material nominally 12 feet long of a hollow rectangular cross section with inside dimensions nominally 3.4 inches by 1.7 inches and a wall thickness of 0.100 inch. Specific dimensions and tolerances apply. Vendor must have demonstrated an extrusion capability for the material. See Note 22. (0172)
