摘要：
This study provides data regarding the characteristics of three carbon fiber reinforced polymer (FRP) systems with three types of resins exposed to accelerated natural weathering conditions according to ASTM G-154-00a for 1000 h. The FRP system consists of three-layered CFRP sheets bonded together with an adhesive. Degussa, Sika and Fosroc were the providers of the three FRP systems. Three-point bend testing according to ASTM D790 showed that ultra-violet (UV) light exposure decreased the flexural modulus of the three-layered FRP samples by 10%, 36% and 2% for Deagussa, Fosroc and Sika samples, respectively. While the reduction for the resin samples was 11.8%, 8.3% and 14.3% for Deagussa, Fosroc and Sika samples, respectively. SEM analysis showed cracking and deterioration in the resin and FRP systems as a result of the exposure to natural weathering. (C) 2008 Elsevier Ltd. All rights reserved.
