摘要

摘要: 设计了光热共引发环氧树脂-聚甲基丙烯酸丁酯(EP-PBMA)树脂,并制备了UV光固化玻璃纤维布增强EP-PBMA树脂基复合材料,研究了不同EP与PBMA质量比的玻璃纤维布/EP-PBMA复合材料在不同加载速率下的拉伸力学性能。结果表明: 玻璃纤维布/EP-PBMA复合材料具有明显的应变率效应;随着加载速率增大,复合材料的拉伸强度和弹性模量呈增大趋势;EP-PBMA树脂基体的组成对应变率效应有明显的影响;玻璃纤维布/EP-PBMA复合材料与纯EP基复合材料相比,在较低的加载速率下具有更高的拉伸强度,但当加载速率达到50 mm/min时拉伸强度较低。

Abstract: The epoxy-poly(butyl methacrylate) (EP-PBMA) resins which can be polymerized and cured by UV and thermal initiation were designed.Based on the EP-PBMA resin, UV curable glass fiber fabric/EP-PBMA composites were prepared.The tensile properties of the glass fiber fabric/EP-PBMA composite samples with different mass ratios of EP to PBMA were tested under different loading rates.According to the results, glass fiber fabric/EP-PBMA composites have a obvious strain rate effect.With the increase of loading rate, the tensile strength and elastic modulus increase.The composition of EP-PBMA resin matrix can affect the strain rate effect greatly.When the loading rate is low, glass fiber fabric/EP-PBMA composites perform better tensile strength than the composites of pure EP matrix.However, when the loading rate reaches 50 mm/min, the tensile strength of glass fiber fabric/EP-PBMA composites becomes lower.
