CHARACTERIZATION OF MATERIALS - SERVICE. SOW AND JUSTIFICATION FOR NON-COMPETITIVE PROCUREMENT: THERMAL AND MECHANICAL CHARACTERIZATION OF CERAMIC MATRIX COMPOSITE/FOAM CORE STRUCTURES. THIS WORK REPRESENTS AN EXTENSION OF CHARACTERIZATION EFFORTS BEGUN UNDER THE LIGHTWEIGHT, NON-METALLIC THERMAL PROTECTION MATERIALS PROJECT. IT EXTENDS THE WORK TO COMPOSITES WITH OTHER TYPES OF CERAMIC FIBER REINFORCEMENT, AS WELL AS ADDITIONAL MATERIAL USING THE FIBER TYPES FROM THE INITIAL STUDY. MAINTAINING THE WORK IN THE SAME TEST LABORATORY (SOUTHERN RESEARCH INSTITUTE) IS REQUIRED TO MAINTAIN CONSISTENCY WITHIN THE DEVELOPING DATABASE. THE SCOPE OF WORK SHALL INCLUDE THE FOLLOWING: (A) CHARACTERIZATION OF MATERIAL FROM FOUR (4) FACESHEET CMC PANELS INCLUDING MEASUREMENTS OF SONIC VELOCITY (IN-PLANE VELOCITY AND DENSITY). OPEN POROSITY, C-SCAN, AND DENSITY. (B) MACHING OF A MINIMUM OF THREE (3) TENSILE SPECIMENS AND THREE (3) ILS SPECIMENS FROM EACH PANEL. (C) DETERMINATION OF COEFFICIENT OF THERMAL EXPANSION (IN-PLANE AND THROUGH-THICKNESS). (D) PROGRESSIVE TESTING OF FOAM CORE STRUCTURES IN THE AIR FORCE LHMEL FACILITY AT INCREASING HEAT FLUX. THERMOGRAPHY AND MICROSTRUCTURAL ANALYSIS OF THESE MATERIALS, AS WELL AS TENSILE TESTING, SHALL BE THE RESPONSIBILITY OF GLENN RESEARCH CENTER.
