Advances in the application of FRP for repairing corrosion damage

Abstract

This paper presents an overview of the application of fibre‐reinforced polymers (FRP) for repairing corrosion‐damaged structures by external wrapping. The rationale, design and durability for such repairs are addressed and significant research findings highlighted. Several field applications are described and new and innovative practices identified. Recommendations are made to improve future performance. Copyright © 2003 John Wiley & Sons, Ltd.

Bond durability of fatigued CFRP-steel double-lap joints pre-exposed to marine environment

“…Cured specimens were fully submerged in a 5% by weight NaCl solution for up to 6 months at three different temperatures (20,40 and 50°C). During submergence specimens were simultaneously subjected to static tensile loads using a hydraulic pump and a calibrated gauge with compressed springs (Fig.…”

“…Though CFRPs are relatively effective, their high stiffness comes with an increased (because of the production and material) cost [19]. Conversely CFRPs considerable reduction in maintenance and repair make them more economical over time [20]. In fact, considerably lower weight and simpler installation of the CFRP components translates to an approximate cost savings of 18% [7] over the traditional steel adaptations.…”

FRP confined concrete columns: Behaviour under extreme conditions

“…Using electrically accelerated corrosion inducing methods, other researchers have suggested that wrapping columns with FRP sheets can reduce corrosion [12,13]. Additionally, some field applications have specifically considered the effects of FRP on the underlying corrosion [14]. Sen [14] conducted a thorough review of the literature in this field and readers are directed to his paper for more detailed discussion of previous research in this area.…”

The research presented in this paper extends this work by considering ''natural'' corrosion.…”

Development of a technology to prevent spontaneous combustion of coal in underground coal mining

“…Fibre-reinforced polymer materials are used in the reinforcement and the repair of structures, and many independent studies have shown that these materials are impermeable to oxygen. These applications have been effective in the repair of corrosion damage since the mid1990s (Alampalli, 2001;Pantazopoulou et al, 2001;Debaiky, Green, and Hope, 2002;Sen, 2003;Wang and Shih, 2004;Badawi and Soudki, 2005;Suh et al, 2007Suh et al, , 2008Winters et al, 2008). Various studies have also shown that fibre-reinforced polymer materials do not prevent corrosion entirely, but reduce the corrosion rate considerably (Baiyasi and Harichandran, 2001;Berver et al, 2001;Wootton, Spainhour, and Yazdani, 2003;Wheat, Jirsa, and Fowler, 2005).…”
