Abstract

Abstract: Carbon fiber–vinyl ester (CFVE) composites are good candidates for use in civil and naval vessels. CFVE composites offer high strength and stiffness-to-weight ratio and superior resistance to electrochemical corrosion. However, during application CFVE composites are exposed to harsh marine environments which can significantly degrade the mechanical properties. Here, the time dependent changes in flexural mechanical properties of CFVE composites due to exposure from marine environments are investigated. Exposure to marine environments are simulated by indoor water immersion, accelerated aging in environmental chambers, and outdoor exposure in a tidal pond. Comparison between the conditions will be discussed in the context of long-term outdoor exposure with controlled laboratory conditions.
