Abstract A program aimed at producing a major advance in the ability to use Carbon Nanotube (CNT) enhanced composites in current and future naval applications is proposed. The proposed framework will comprise material characterization, multi-scale modeling and experiments that span and integrate length scales from nano to structural level. The effect of material and architectural variations across the length scales will be investigated using scale appropriate stochastic representative volume elements and unit cells. Damage initiation and its evolution will be addressed directly within the multi-scale framework. Temperature effects will also be studied to investigate the change in thermal conductivity of composites integrated with relatively low volume fractions of CNTs. To ensure Navy relevance, aggressive collaborations with Navy personnel will be pursued during the project to optimize our understanding of crucial challenges, the use of available test data, and the likelihood of transitioning results from the project into DoD practice. The proposed project is organized into three tasks: (1) Multi-scale modeling from nano to macro level; (2) Temperature effects in multi-scale modeling; (3) Material characterization, testing and validation.
