Advances in structural adhesives have permitted engineers to contemplate the use of bonded joints in areas that have long been dominated by mechanical fasteners and welds. In recent years, an advanced, bonded composite repair technology has made great strides in commercial aviation use. Extensive testing, analysis, and successful flight performance history—obtained through joint programs between the Sandia Labs–FAA Airworthiness Assurance Center and the aviation industry—has established the viability and durability of bonded composite patches as a permanent repair on metallic, commercial aircraft structures. With this foundation in place, efforts are underway to adapt bonded composite repair technology to civil structures. Specifically, a long-term study has demonstrated the feasibility of applying composite repairs to steel structures such as mining trucks, oil recovery equipment, buildings, and bridges. This paper presents the application of high-modulus, fiber-reinforced polymer (FRP) composite patches to repair a steel bridge on Interstate 10. It discusses the array of engineering activities that were completed in order to establish this repair technology for use on civil structures. Results from the I-10 bridge repair are presented. The factors influencing the durability of composite patches in severe field environments are discussed along with related laminate design, analysis, installation, and nondestructive inspection issues. The goal of this pilot program is to eliminate any obstacles to the use of composite doubler repairs and allow authorities to exploit the engineering and economic advantages for the refurbishment of steel structures.
