The Center for Integration of Composites into Infrastructure (CICI) is a NSF I/UCRC that utilizes the expertise of West Virginia University, North Carolina State University, the University of Miami, and Texas A & M University/University of Texas at Arlington with an objective of accelerating the adoption of Fiber Reinforced Polymer (FRP) composites and geosynthetics into infrastructure applications by utilizing industry wide cooperation. The American Society of Civil Engineers gives U.S. infrastructure a grade of D+, with a 10 year funding gap of $1.44 trillion, leading to losses of $3.9 trillion to the U.S. GDP and 2.5 million fewer jobs. FRP composites and geosythentics are gaining acceptance for infrastructure due to their corrosion resistance, ease of installation, and proof-of-concept from field demonstrations in service for up to four decades. The biggest advantage to composite materials is durability, as they do not corrode or rot allowing for an extended service life thus extending taxpayer dollars. With the support of NSF, CICI currently consists of a consortium of four universities and 31 industry members, bringing together faculty, students, practitioners, manufacturers, trade organizations and government agencies to overcome the obstacles to widespread deployment of composites, forging lasting partnerships, and educating students, engineers and contractors. CICI focuses on four research thrusts. First, research on material development, manufacturing, and characterization allows for the development of new composite materials and recycling of discarded polymer composites with a clear understanding of the physico-chemical and mechanical properties. Second, the durability and aging of composites is evaluated under accelerated aging and by examining existing structures to ensure that composites can have long service lives under harsh environmental conditions. Third, design, implementation and evaluation of composites in new construction and rehabilitation of existing structures.. Fourth, CICI contributes to the development of standards, specifications, and guide documents required for the deployment of new technologies into commercial practice. North Carolina State University provides the capability of testing and validating FRP systems on full-scale members of critical infrastructure to facilitate acceptance and technology transfer. Fundamental material level research is also possible to quantify the durability of composite materials, the development of new multi-functional composites, and structural health monitoring.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.

复合材料与基础设施集成中心(CiCi)是一个NSF I/UCRC，它利用西弗吉尼亚大学、北卡罗来纳州立大学、迈阿密大学和德克萨斯农工大学/德克萨斯大学阿灵顿分校的专业知识，旨在通过整个行业的合作，加速将纤维增强聚合物(FRP)复合材料和土工合成材料应用到基础设施应用中。美国土木工程师协会对美国基础设施的评级为D+，10年资金缺口为1.44万亿美元，导致美国GDP损失3.9万亿美元，就业岗位减少250万个。玻璃钢复合材料和土工合成材料因其耐腐蚀性、安装简便性以及长达40年的现场示范概念验证而获得基础设施的认可。复合材料的最大优势是耐用性，因为它们不会腐蚀或腐烂，从而延长了纳税人的使用寿命。在NSF的支持下，CiCi目前由四所大学和31个行业成员组成的联盟，将教师、学生、从业者、制造商、贸易组织和政府机构聚集在一起，以克服广泛部署复合材料、建立持久合作伙伴关系以及培养学生、工程师和承包商的障碍。CiCi专注于四个研究方向。首先，对材料开发、制造和表征的研究有助于开发新的复合材料和回收废弃的聚合物复合材料，并对其物理化学和机械性能有明确的了解。其次，在加速老化条件下，通过检查现有结构来评估复合材料的耐久性和老化，以确保复合材料能够在恶劣的环境条件下具有较长的使用寿命。第三，复合材料在新建和既有结构修复中的设计、实施和评估。第四，CiCi帮助制定将新技术部署到商业实践中所需的标准、规范和指导性文件。北卡罗来纳州立大学提供在关键基础设施的全尺寸成员上测试和验证FRP系统的能力，以促进验收和技术转让。基础材料水平的研究也可以量化复合材料的耐久性、新型多功能复合材料的开发和结构健康监测。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。
