碳纤维乙烯基酯（CFVE）复合材料是民用和海军舰艇的良好候选材料。 CFVE 复合材料具有高强度和刚度重量比以及优异的耐电化学腐蚀性能。然而，在应用过程中，CFVE 复合材料暴露在恶劣的海洋环境中，这会显着降低机械性能。在此，研究了由于暴露于海洋环境而导致的 CFVE 复合材料弯曲机械性能随时间的变化。通过室内浸水、环境室中的加速老化以及潮汐池中的室外暴露来模拟暴露于海洋环境。将在受控实验室条件下长期户外暴露的背景下讨论这些条件之间的比较。 (C) 2016 Elsevier Ltd. 保留所有权利。
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. (C) 2016 Elsevier Ltd. All rights reserved.
