Abstract:The overall goal of this project is the experimental evaluation and design of unfilled and concrete-filled FRP composite piles for load-bearing in bridges. This report covers Task 5, Laminate Durability Testing.
Mechanical properties of the FRP material were examined using flat witness FRP plates with 2 layers of reinforcing fabric and a nominal thickness of 6.4 mm (0.25 in). The FRP material was tested after exposure to four environmental conditions to verify compliance with the American Association of State Highway and Transportation Officials Guide Specification for Design of Bonded FRP Systems for Repair and Strengthening of Concrete Bride Elements (2012) durability requirements. The environmental conditions were: a) Alkali environment exposure; b) Water exposure; c) Freeze-thaw cycles; and d) UV/condensation exposure.
