Doe needs to develop carbon-carbon composites to line the inside walls of future fusion devices. the carbon-carbons should have the highest possible resistance to fast neutronswhile maintaining high thermal conductivity and good mechanical properties. this project will fabricate a new generation… More

There is a need for lightweight c/c composites that can be tailored to manage rapidly generated, very high heat loads in electronic components and space and missile structures for navsea weapon systems. the innovation in this program is to utilize a high char yield mesophase pitch and b(4)c doped… More

High thermal conductivity carbon-carbon composites are candidates for the first wall of the international thermonuclear experimental reactor (iter). however, carbon-carbon composites have relatively high erosion rates caused by hydrogen bombardment when the plasma disrupts. such erosion may require… More

Advanced aircraft designs require thechnology improvements that incorporate the use of advanced materials and material systems for high specific stiffness and temperature capabilities. Improved crack detection and material property measurement techniques are required to support the development and… More

Doe needs to develop high thermal conductivity, irradiation stable first wall armor for the international thermonuclear experimental reactor (inter). a high thermal conductivity graphite will be developed in phase i by adding metals in the premix during fabrication. metals such as titanium, silicon,… More
