Planning IUCRC at University of Tennessee/Knoxville: Center for [Digital Composite Joining and Repair]

该奖项支持一个工业-大学合作研究中心(IUCRC)的规划研讨会，旨在改进复合材料连接和修复(CJAR)技术。复合材料对几个行业的竞争力至关重要，包括汽车、制造、能源、生物医学、国防和航空航天。目前的CJAR做法是高度专业化、劳动密集型的，需要有经验的技术人员进行关键检查、维护和维修。包括田纳西-诺克斯维尔大学、佐治亚理工学院和奥克兰大学在内的合作机构将与美国经济中的汽车、航空航天、国防、能源和生物医学部门的各种工业公司合作。田纳西大学的D-CJAR基地将与先进复合材料制造创新研究所(IACMI)、橡树岭国家实验室(ONR)-(制造示范设施(MDF)和碳纤维技术设施(CFTF))、材料供应商、设备制造商和最终用户接触。例如Magnum Venus Products(MVP)、资源光纤、Mini-Fibers、HTS IC等。合作大学的教师和学生团队将与行业成员合作开展竞争前研究，开发和传播基础和应用技术/知识，以促进快速、可靠和经济高效的复合材料连接和修复，总体目标是在十(10)年内显著降低成本、周期时间和CJAR操作的变化。目标是将当前的劳动密集型和专业化过程转变为基于科学的、自动化和数字化的CJAR过程，田纳西大学D-CJAR网站将主要专注于开发用于先进复合材料、金属和混合动力材料的多材料连接和修复的CJAR技术。我们期待着围绕CJAR在几个领域和知识领域取得进展，包括(1)多材料连接的设计和分析，(2)工艺创新，(3)材料和工艺工程，以及(4)测试和无损评估(NDE)。我们将把先进的数字技术，包括先进的计算建模、传感、材料表征和机器学习应用到CJAR的实际案例中，这也将促进在合作大学从事项目的学生的教育和劳动力准备。新材料和工艺的开发将促进许多CJAR任务和工艺的标准化、模型化和自动化，为整个复合材料供应链的行业合作伙伴节省成本、缩短周期并提高性能，有助于保持美国在这个不断增长的行业的全球领导地位。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award supports a planning workshop for an Industry-University Cooperative Research Center (IUCRC) aimed at improving composite material joining and repair (CJAR) technologies. Composite materials are vital to the competitiveness of several sectors, including automotive, manufacturing, energy, biomedical, defense and aerospace. Current CJAR practices are highly specialized, labor-intensive, and require experienced technicians for critical inspection, maintenance and repair. Partner institutions including The University of Tennessee-Knoxville, Georgia Institute of Technology and Oakland University will collaborate with various industrial companies, in the automotive, aerospace, defense, energy, and biomedical sectors of the US economy. The University of Tennessee site of D-CJAR will engage the Institute for Advanced Composites Manufacturing Innovation (IACMI), Oak Ridge National Laboratory (ONR) - (Manufacturing Demonstration Facility (MDF) and Carbon Fiber Technology Facility (CFTF)), material suppliers, equipment manufacturers and end users. Examples include Magnum Venus Products (MVP), Resource Fiber, Mini-Fibers, HTS IC among others. Faculty and student teams at the partner universities will work with industry members to conduct pre-competitive research to develop and disseminate basic and applied technologies/knowledge to facilitate rapid, reliable, and cost-effective composite joining and repair, with an overall goal of significantly reducing costs, cycle time, and variation of CJAR operations within ten (10) years.With the goal of transforming the current labor-intensive and specialized processes into science-based, automated, and digital CJAR processes, the University of Tennessee site of D-CJAR will primarily focus on developing CJAR technologies for multi-material joining and repair of advanced composites, metals and hybrids. We expect advances in several fields and knowledge domains around CJAR, including (1) design and analysis of multi-materials joining, (2) process innovations, (3) materials and process engineering, and (4) testing and nondestructive evaluation (NDE). We will apply advanced digital techniques, including advanced computational modeling, sensing, materials characterization, and machine learning to practical CJAR cases that will also advance the education and workforce preparedness of students working on projects at the partner universities. Development of new materials and processes would facilitate standardization, modeling, and automation of many CJAR tasks and processes, producing cost savings, faster cycle times, and enhanced performance for industry partners across the entire composites supply chain, contributing to the maintenance of U.S. global leadership in this growing sector.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
