玻纤增强乙烯基酯树脂在漠河地区的自然老化研究

摘要

Glass fiber reinforced vinyl resin samples exposure to the atmosphere for three years and eight years in the library in Mohe region were studied. The tensile strength,tensile modulus,flexural strength,flexural modulus and compressive strength,such 5 kinds of mechanical properties and their changing tendency were investigated. The samples were analyzed by scanning electron microscope and the service life of glass fiber reinforced vinyl ester resin in Mohe County was predicted,and the required time for its bending property retention rate decreased to 75%was calculated.%对玻纤增强乙烯基酯树脂在漠河地区的大气暴露三年和库内暴露八年的样品分别进行研究，考察了其拉伸强度、拉伸弹性模量、弯曲强度、弯曲弹性模量、压缩强度5种力学性能及变化趋势；对样品进行了扫描电镜微观分析；同时对漠河地区的玻纤增强乙烯基酯树脂进行了寿命预测，计算出材料弯曲性能保留率下降到75%时所需时间。
