Fiber-reinforced polymers (FRPs) are used increasingly as concrete reinforcement as a cost-effective alternative to steel bars. Given their corrosion resistance, light weight, and high strength, FRP bars have a 20-year history in Canada in infrastructure such as bridge decks, parking garages, and continuous pavements. The lack of appropriate data about the long-term durability poses a major obstacle to broader acceptance and mass implementation of FRP bars. Moreover, the applicants are conducting new research on the development of FRP ecomaterials based on natural fibers and biosourced resins. These activities require detailing research work involving the characterization of fiber-surface chemical treatments, and fiber/resin interface analysis.

纤维增强的聚合物（FRP）越来越多地用作混凝土钢筋作为钢棒的一种经济有效的替代品。鉴于它们的耐腐蚀性，轻巧的重量和高强度，FRP酒吧在加拿大在基础设施中拥有20年的历史，例如桥梁甲板，停车场和连续的人行道。缺乏有关长期耐用性的适当数据为更广泛的接受和大规模实施FRP杆构成了主要障碍。此外，申请人正在对基于天然纤维和生物化树脂的FRP生态材料的开发进行新的研究。这些活动需要详细介绍涉及纤维表面化学处理和纤维/树脂界面分析的研究工作。
