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50mm/min时拉伸强度较低。
Epoxy-polybutylmethacrylate (EP-PBMA) resin was designed and the UV-curable glass fiber cloth was used to enhance EP-PBMA resin-based composites. The effects of different mass ratios of EP to PBMA Tensile Mechanical Properties of Glass Fiber Cloth / EP-PBMA Composites at Different Loading Rates. The results show that the glass fiber cloth / EP-PBMA composites have obvious strain rate effect. With the increase of loading rate, the tensile strength and elastic modulus of the composites increase. The composition of the EP- The rate effect has a significant impact; glass fiber cloth / EP-PBMA composite material compared with the pure EP-based composite material at lower loading rate has higher tensile strength, but when the loading rate of 50mm / min pull Lower strength.
