This objective of this collaborative research project will be to design test apparatus to examine yarn slippage during thermostamping, to formulate material constitutive and interface models to capture macroscale behavior while considering the microscopic constituents; to propose failure criteria linking to the formability of this material (woven architecture and matrix constituents). The overall objective is to create design rules to best utilize the material potential. These challenging and fundamental issues will be addressed in collaboration between Northwestern, U Mass-Lowell, industry, and international researchers. The broader impacts of this research are numerous. The environmental concern for reduced emissions and fuel consumption has created enormous opportunities for introducing woven-fabric reinforced composites into high-volume consumer products as they possess outstanding structural (car bodies, floor pans, truck beds) and energy-management (for crash situations) properties. Thermostamping has demonstrated its potential as the means to reduce manufacturing costs for mass-production applications. The PI will coordinate an international benchmarking program on material tests, thermostamping tests and modeling methods among researchers in the U.S., Europe and Asia.

该协作研究项目的这个目标将是设计测试设备，以检查恒温器期间的纱线滑移，以制定材料本构和界面模型，以捕获宏观的行为，同时考虑微观成分。提出与该材料（编织体系结构和矩阵成分）相关的故障标准。总体目标是创建设计规则，以最好地利用物质潜力。这些具有挑战性和基本的问题将在西北，美国大众，工业和国际研究人员之间的合作中解决。这项研究的更广泛影响是许多。减少排放和燃料消耗的环境问题为将编织装饰的增强复合材料引入了高批量消费产品，因为它们具有出色的结构性（汽车，地板，卡车床）和能源管理（用于崩溃情况）的物业。恒温器已证明其潜力是降低批量生产应用的制造成本的手段。 PI将在美国，欧洲和亚洲研究人员中协调有关材料测试，恒温器测试和建模方法的国际基准测试计划。
