Efficient infrastructure systems such as highways, bridges, buildings, pipelines, flood control systems and utilities are all necessary for a healthy economy and comfortable standard of living. Concrete, steel and timber are the backbones of physical infrastructure. High strength polymer composites have been used for aerospace structures for about five decades and their use in civil infrastructure spans about 20 years. To accelerate the adoption of polymer composites into infrastructure, the NSF I/UCRC Center of the Integration of Composites into Infrastructure (CICI) was established as a joint effort of West Virginia University (WVU), North Carolina State University (NCSU) and the University of Miami. Recently, NSF has awarded a travel grant to establish an additional CICI site at Nanjing University of Technology in China. The NSF I/UCRC program brings together universities, private companies and government agencies together to leverage the research dollars for all parties by engaging in highly cooperative research. CICI's work with civil infrastructure has a tremendous effect on daily life, thus the Nation as a whole benefits as composite and hybrid materials lead to infrastructure systems of higher safety, shorter construction times and longer life spans at a reduced overall cost and improved labor productivity with the creation of new and higher skilled job opportunities. Member companies and end users benefit from the interaction with others in their field including highly trained students, with over 100 students expected to pass through CICI in the next 5 years. CICI is prolific technology transfer machine, exceeding the output for most I/UCRCs through the publishing of journal articles and conference presentations to promote the scientific research and knowledge dissemination. Broadly speaking, the technical focus of CICI can be broken into four different areas. Initially, fundamental research projects are undertaken to broaden the knowledge base on infrastructure composites. This includes lifecycle performance, aging studies, evaluation of bond strength within a composite and as a substrate, and many others. From this on-going research, products are being developed that can be mass-implemented in infrastructure markets, including innovative hollow core or basalt fiber FRP rebar, waterway products that are noncorrosive or fabric reinforced cementitious composites for masonry wall strengthening and many others. The implementation of these products is the next focus area and is primarily accomplished through the development of codes and specifications. CICI has worked on the ASCE LRFD pultruded GFRP composites code, ASTM specifications, ACI building design and construction codes, the International Code Council and IIFC. Finally, CICI has an evaluation component based on IAB member feedback to ensure the composites that are implemented in the field are performing as designed as a part of our long-term performance program. Thus, through research, development, implementation and evaluation, CICI is involved in all facets of composite product evolution.

高速公路、桥梁、建筑、管道、防洪系统和公用设施等高效的基础设施系统对于健康的经济和舒适的生活水平都是必要的。混凝土、钢材和木材是物质基础设施的支柱。高强度聚合物复合材料在航空航天结构中的应用已有约 50 年的历史，在民用基础设施中的应用也有约 20 年的历史。为了加速聚合物复合材料在基础设施中的应用，西弗吉尼亚大学 (WVU)、北卡罗来纳州立大学 (NCSU) 和迈阿密大学共同成立了 NSF I/UCRC 复合材料集成基础设施中心 (CICI)。最近，美国国家科学基金会 (NSF) 授予了一笔旅行补助金，用于在中国南京工业大学建立一个额外的 CICI 站点。 NSF I/UCRC 项目将大学、私营公司和政府机构聚集在一起，通过高度合作的研究来为各方利用研究资金。 CICI 在民用基础设施方面的工作对日常生活产生了巨大影响，因此整个国家受益，因为复合材料和混合材料导致基础设施系统安全性更高，施工时间更短，使用寿命更长，总体成本更低，劳动生产率更高，创造了新的更高技能的就业机会。会员公司和最终用户受益于与各自领域的其他人（包括训练有素的学生）的互动，预计未来 5 年内将有超过 100 名学生通过 CICI。 CICI 是多产的技术转让机器，通过发表期刊文章和会议演讲来促进科学研究和知识传播，其产出超过了大多数 I/UCRC。从广义上讲，CICI 的技术重点可以分为四个不同的领域。最初，开展基础研究项目是为了扩大基础设施复合材料的知识基础。这包括生命周期性能、老化研究、复合材料内和作为基材的粘合强度评估等等。通过这项持续的研究，正在开发可在基础设施市场大规模实施的产品，包括创新的空心或玄武岩纤维玻璃钢钢筋、用于砖石墙加固的耐腐蚀水道产品或织物增强水泥基复合材料等。这些产品的实施是下一个重点领域，主要通过代码和规范的开发来完成。 CICI 致力于制定 ASCE LRFD 拉挤 GFRP 复合材料规范、ASTM 规范、ACI 建筑设计和施工规范、国际规范委员会和 IIFC。最后，CICI 有一个基于 IAB 成员反馈的评估组件，以确保现场实施的复合材料的性能符合我们长期性能计划的设计。因此，通过研究、开发、实施和评估，CICI 参与了复合材料产品演进的各个方面。
