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.

高效的基础设施系统，如高速公路、桥梁、建筑、管道、防洪系统和公用事业，都是健康的经济和舒适的生活水平所必需的。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用于航空航天结构已有近50年的历史，在民用基础设施中的应用也有近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，由西弗吉尼亚大学（WVU）、北卡罗来纳州立大学（NCSU）和迈阿密大学共同努力，成立了NSF I/UCRC复合材料与基础设施集成中心（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。美国国家科学基金会I/UCRC项目将大学、私营公司和政府机构聚集在一起，通过开展高度合作的研究，为各方利用研究资金。CICI在民用基础设施方面的工作对人们的日常生活产生了巨大的影响，因此整个国家都受益于复合材料和混合材料，这些材料带来了更高安全性的基础设施系统，缩短了施工时间，延长了使用寿命，降低了总成本，提高了劳动生产率，创造了新的和更高技能的工作机会。会员公司和最终用户受益于与其他同行的互动，包括训练有素的学生，预计在未来5年内将有100多名学生通过CICI。CICI是一个多产的技术转移机器，通过发表期刊文章和会议报告来促进科学研究和知识传播，超过了大多数I/ ucrc的产出。从广义上讲，CICI的技术重点可以分为四个不同的领域。最初，进行基础研究项目，以扩大基础设施复合材料的知识库。这包括生命周期性能、老化研究、复合材料内部和作为基材的结合强度评估等等。从这项正在进行的研究中，正在开发可以在基础设施市场大规模实施的产品，包括创新的空心核心或玄武岩纤维FRP钢筋，无腐蚀性的水道产品或用于砖石墙加固的织物增强胶凝复合材料等等。这些产品的实现是下一个重点领域，主要通过开发代码和规范来完成。CICI参与了ASCE LRFD拉伸玻璃钢复合材料规范，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，以确保在现场实施的复合材料按照设计执行，这是我们长期性能计划的一部分。因此，通过研究、开发、实施和评估，CICI参与了复合材料产品发展的各个方面。
