New Generation Hybrid Carbon/Ceramic Nanocomposites

Based on in-depth experience with advanced optical ceramics, nano-particle coating, nanoceramic sintering and superplasticity deformation, in this program, AGILTRON Inc. and Florida International University, and University of California at Davis propose to develop next generation airframe and engine materials made of CNT/alumina nano-composites. The proposed approach uniquely combines low-cost and potentially large scale technology of in situ CNT growth on nano-particles and low temperature, short duration spark plasma sintering. This nanocomposite may represent an unprecedented opportunity for next generation IR window material because of its CNT-enabled high superplasticity, nano-enhanced mechanical strength, hardness and toughness, and intrinsic chemical and environmental stability. Due to the high strain rate superplasticity of the proposed composite, direct-shape engine components can be made through superplastic deformation at a relative low cost. The CNT enabled composite technology is promising to provide performance attributes that are beyond current technology. In this program, we anticipate to demonstrate drastic improvements in cost, size, thermal mechanical performance, and superplasticity, which have not been attainable before. The approach¡_s feasibility will be demonstrated in Phase I.
