Intermediate Temperature Carbon/Carbon Structures

"The main objective will be to develop and evaluate carbon/carbon (C/C) structures designed for long term applications at 700-1200¿F and with at least 2X improvement in compressive and tensile strength over current C/C composites in this temperature range.These C/C composites will provide a lightweight structural material suitable for many critical applications, including replacement of titanium components in applications in the 700 to 1200F temperature range. Polymer structures with high char yield anddesirable mechanical and physical properties will be investigated. We will also develop materials that provide thermo-oxidatively stable impregnants and coatings. Carbon-carbon composites will be fabricated and mechanical, physical and morphologicalproperties will be evaluated and demonstrated. During the Phase I program, UDC in collaboration with research partner will define potential materials and applications goals. This Phase I program will demonstrate the feasibility of UDC's innovativeformulations, processing and oxidation protection approaches for developing C/C structures with 700-1200¿F use capability. The Phase I program will demonstrate superior physical properties, oxidation, chemical and thermal stability and processability ofspecimens. At the end of Phase I, we will provide a report with results and conclusions, and a Phase II plan, schedule and cost estimate. The developed C/C composites will provide a lightweight structural material suitable for many critical applications,including replacement of titanium components in applications in the 700 to 1200F temperature range. Composite materials have already found widespread application in the commercial market. The high performance combined with hightemperature capability will lead to new applications in all markets, including aerospace, military or commercial.
