The objectives of this research are to characterize the nanostructures of carbon nanotube-reinforced composite materials, explore the machinability of these materials and develop multiscale mechanisitic models for the prediction of their machinability. The ultimate goal of the research is to produce a carbon nanotube-reinforced composite material that is optimized for both its physical properties and its machinability. The approach to this research will include a blend of experimentation and modeling work to study machinability performance as a function of the physical properties of CNT composites and their microstructures and employ multi-scale modeling methods to capture these performance characteristics mathematically. Then, employing finite element simulations and constitutive laws, machinability performance will be studied in detail. Improving the manufacturability of these materials will further enable designers to exploit their remarkable properties in a range of emerging application areas including health care, communications, and national defense. Second, the project includes the training of both undergraduate and graduate students in the fields of nanomaterials and nanomaterials processing. And finally, the project, through a number of mechanisms, will reach out to under-represented minorities to inspire them to seek careers in the field of nanoscience and nanotechnology.

本研究的目标是表征碳纳米管增强复合材料的纳米结构，探索这些材料的可加工性，并开发多尺度力学模型预测其可加工性。 该研究的最终目标是生产一种碳纳米管增强的复合材料，该材料的物理性能和可加工性都得到了优化。 这项研究的方法将包括实验和建模工作的混合，以研究作为CNT复合材料及其微观结构的物理特性的函数的可加工性能，并采用多尺度建模方法来数学地捕获这些性能特征。然后，采用有限元模拟和本构关系，切削性能将进行详细研究。提高这些材料的可制造性将进一步使设计师能够在一系列新兴应用领域（包括医疗保健、通信和国防）中利用其卓越的性能。 第二，该项目包括在纳米材料和纳米材料加工领域培训本科生和研究生。 最后，该项目将通过一系列机制接触代表性不足的少数群体，激励他们在纳米科学和纳米技术领域寻求职业。
