Planning IUCRC Oakland University Center for Digital Joining and Repair

该奖项支持一个新的产学合作研究中心(IUCRC)的规划研讨会，旨在改善复合材料连接和修复(CJAR)。复合材料对几个重要经济部门的健康和竞争力至关重要，包括汽车、制造、能源和航空航天。由于复合材料的成分不同，元素浓度/取向和公差差异很大，目前的CJAR实践是高度专业化的，劳动密集型的，需要经验丰富的技术人员成功和可靠地完成工作。合作机构奥克兰大学、佐治亚理工学院和田纳西-诺克斯维尔大学将在美国经济的汽车、航空航天和能源领域与民用和国防工业合作。奥克兰大学D-CJAR将主要与汽车(通用汽车、福特、菲亚特克莱斯勒、宝马、通用动力陆地系统公司)、制造业(John Deere)和民用飞机发动机(Pratt&amp；Whitney)行业的公司合作，还将与国家制造科学中心和美国海军研究实验室合作。合作大学的教师和学生团队将与行业成员合作，开发和传播关于方法、技术、工具和劳动力创新的基础和应用竞争前研究，以促进快速、可靠和经济高效的复合材料连接和维修，总体目标是在10年内降低成本、周期时间和CJAR操作的变化。奥克兰大学D-CJAR中心的工作范围将包括汽车、飞机、基础设施(风力涡轮机叶片等)的部件。以及完全或部分由复合材料制成的防护设备，目标是将目前的劳动密集型和专门工艺转变为以科学为基础的、自动化的、数字化的CJAR工艺。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)设计和分析，(2)材料和工艺工程，(3)测试和无损检测，以及(4)数据分析。我们将把各种先进的数字技术应用到CJAR的实际案例中，包括先进的计算建模、传感、材料表征和机器学习，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 a new Industry-University Cooperative Research Center (IUCRC) aimed at improving composite material joining and repair (CJAR). Composite materials are vital to the health and competitiveness of several important economic sectors, including automotive, manufacturing, energy, and aerospace. As composites have different compositions and element concentration/orientation and tolerances that vary widely, current CJAR practices are highly specialized, labor-intensive, and require experienced technicians to complete the work successfully and reliably. Partner institutions Oakland University, Georgia Institute of Technology, and the University of Tennessee-Knoxville will work collaboratively with both the civilian and defense industries, in the automotive, aerospace, and energy sectors of the US economy. The Oakland University D-CJAR will primarily work with firms in the automotive (GM, Ford, Fiat Chrysler, BMW, General Dynamics Land Systems), manufacturing (John Deere), and civil aircraft engine (Pratt & Whitney) industries, and also with the National Center for Manufacturing Sciences and the U.S. Naval Research Laboratory. Faculty and student teams at the partner universities will work with industry members to develop and disseminate basic and applied precompetitive research on methodologies, technologies, tools, and workforce innovations to facilitate rapid, reliable, and cost-effective composite joining and repair, with an overall goal of reducing costs, cycle time, and variation of CJAR operations within 10 years.The scope of work for the Oakland University D-CJAR center will include components of automotive, aircraft, infrastructure (wind turbine blades, etc.) and protective equipment that are wholly or partially made with composite materials, with the goal of transforming the current labor-intensive and specialized processes into science-based, automated, digital CJAR processes. We expect advances in several fields and knowledge domains around CJAR, including (1) design and analysis, (2) materials and process engineering, (3) testing and NDE, and (4) data analytics. We will apply diverse 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.
