The Center for Composite and Hybrid Materials Interfacing (CHMI) seeks to generate knowledge and capabilities in joining, bonding, and maintenance of composite and hybrid material structures by applying reliable, data-driven, automated processes using advanced analytical, computational, experimental, and digital techniques and tools. It is a partnership between Oakland University (OU), Georgia Institute of Technology (GT) and University of Tennessee, Knoxville (UTK). The significant advantages of lightweight composite and hybrid materials for aerospace, automotive, infrastructure, and biomedical applications come with scientific, technical, and economic challenges that must be addressed for the U.S. to be a global manufacturing leader. The interfaces in these materials systems are identified as a critical barrier due to fabrication costs and inconsistent performance (especially in aggressive environments). The goal of CHMI is to significantly reduce cost (≥50%), cycle time, and variation of such engineering operations in ten years. The OU Site is home to state-of-the-art facilities and expert researchers at its Fastening and Joining Research Institute (FAJRI), which includes a wide range of equipment in its composite joining labs, material properties and manufacturing processing lab, and chemistry labs. The OU faculty have diverse expertise that spans material joining, nondestructive testing, material characterization, artificial intelligence, modeling/simulation, data analytics, advance manufacturing, and validation testing. The three partnering universities have well-established, complementary expertise in lightweight composite and hybrid materials. They will work together on four industry-inspired research thrust areas: (1) Design, Modeling and Analysis, (2) Materials and Process Engineering, (3) Testing and NDE, and (4) Secure Data and Digital Technologies. Each university has emphasized different industry sectors (GT-Aerospace, OU-Automotive/Ground Vehicle, UTK-Infrastructure and Biomedical), which ensures the inclusion of university and industry perspectives across a wide range of U.S. manufacturing. The CHMI IUCRC will develop a Convergent Research Development Environment that will identify and conduct industry-inspired pre-competitive, innovative research in the area of interfacing composites and hybrid materials. The OU Site will focus on computation and design, processing/fabrication, characterization and testing, non-destructive evaluation (NDE), and data analytics. Specifically, research efforts will include: electromagnetic-sensitive additives for reversible adhesion of hybrid material joints, volatile organic compound failure analysis of autoclave-bonded panels, modeling of predictive emission for adhesive hybrid material joints, machine learning and knowledge-based models for threaded composite and hybrid material joint systems, NDE methods using experimental and computational digital shearography for composite and hybrid materials interfaces, and the development of other breakthrough technologies that drive industry to mitigate risk and improve efficiency.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.

复合材料和混合材料界面中心（CHMI）寻求通过使用先进的分析、计算、实验和数字技术和工具，应用可靠的、数据驱动的自动化过程，在复合材料和混合材料结构的连接、粘合和维护方面产生知识和能力。它是奥克兰大学（OU），佐治亚理工学院（GT）和田纳西大学诺克斯维尔分校（UTK）之间的合作伙伴关系。轻质复合材料和混合材料在航空航天、汽车、基础设施和生物医学等领域的显著优势带来了科学、技术和经济方面的挑战，美国要成为全球制造业的领导者，就必须解决这些挑战。由于制造成本和不一致的性能（特别是在恶劣环境中），这些材料系统中的界面被认为是一个关键障碍。CHMI的目标是在十年内显著降低此类工程操作的成本（≥50%）、周期时间和变化。俄勒冈州立大学现场是其紧固和连接研究所（FAJRI）最先进的设施和专家研究人员的所在地，其中包括复合材料连接实验室，材料性能和制造加工实验室以及化学实验室的各种设备。公开大学的教师拥有不同的专业知识，涵盖材料连接、无损检测、材料表征、人工智能、建模/仿真、数据分析、先进制造和验证测试。这三所合作大学在轻质复合材料和混合材料方面拥有完善的互补专业知识。他们将在四个行业启发的研究重点领域合作：(1)设计，建模和分析，(2)材料和工艺工程，(3)测试和无损检测，(4)安全数据和数字技术。每所大学都强调不同的行业领域（gt -航空航天，ou -汽车/地面车辆，utk -基础设施和生物医学），这确保了在广泛的美国制造业中包含大学和行业的观点。CHMI - IUCRC将开发一个融合研究发展环境，在界面复合材料和混合材料领域确定并开展行业激励的竞争前创新研究。OU网站将专注于计算和设计，加工/制造，表征和测试，无损评估（NDE）和数据分析。具体而言，研究工作将包括：用于复合材料接头可逆粘附的电磁敏感添加剂，热压釜粘合板的挥发性有机化合物失效分析，粘合剂混合材料接头的预测发射建模，螺纹复合材料和混合材料接头系统的机器学习和基于知识的模型，使用实验和计算数字剪切成像的复合材料和混合材料界面的NDE方法，以及其他突破性技术的发展，推动行业降低风险，提高效率。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
