Keywords: composite materials, fiber reinforced composites, research roadmap, aging infrastructure
Can we improve service lifetime and reduce maintenance costs by repairing or replacing ageing metallic infrastructure with composite materials?
Engineered composite materials are made from two or more constituent materials that, when combined, produce a material with characteristics different from the individual components. For example, concrete is the most widely used composite material. Fiber-reinforced polymers are also commonly used as construction materials. Reclamation has identified several infrastructure components where the corrosion resistance, lightweight nature, and impact and abrasion resistance of construction composite materials may provide an excellent alternative to steel.
Need and Benefit
Reclamation has a strong history in concrete research and has recently conducted research and field installations of fiber-reinforced polymers for pipeline repair. However, there are both immediate and long-term areas where Reclamation could benefit from incorporating additional composite products into our infrastructure repertoire. Of primary interest are replacements for ageing metallic structures that have shown degradation due to corrosion and abrasion or impact. These types of structures could possibly be repaired or replaced with composite materials, thereby extending the typical service life of the structures and reducing maintenance costs. Steel requires corrosion protection usually in the form of protective coatings which have increased in cost significantly since construction of many Bureau projects. In addition, the expected service life of modern coatings is shortly than legacy coatings such as vinyl resins and coal tar enamels which have been phased out. These factors may make non-traditional materials such as composites more competitive with steel from a life cycle standpoint.
By partnering with the USACE-CERL, the two agencies will be able to identify areas of mutual interest in composites research, propose individual or collaborative efforts on specific topics, and perform complementary research to benefit both agencies.
