    Abstract

    Determining long-term behavior of bonded CFRP systems requires developing an accelerated aging test method for CFRP applications. This paper examines the development of test methodology and specimen for both flexure and direct tension behavior of bonded CFRP materials using a specimen submerged in a water bath subject to elevated temperature. Test results of three commercial CFRP systems are presented. A discussion of accelerated aging is included in the developmental effort.
