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 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 provide unprecedented performance for next generation wear resistant 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. This CNT enabled composite technology provides performance attributes that are beyond current technology. In the Phase I program, we successfully demonstrated the feasibility of the proposed approach through small-scale fabrication and evaluation. In Phase II, we will optimize and scale up the fabrication process of the proposed nano-composite to achieve unprecedented performance at low cost. The anticipated scaled process includes multi-kilogram/batch powder synthesis capability and up to 75mm in diameter fabricated part size.
