摘要/Abstract

摘要： 为探讨拉挤型玻璃纤维增强复合材料(GFRP)层合板的压缩力学性能及破坏机理,以基体树脂和纤维含量为变化参数,对6种拉挤型多向GFRP层合板进行了纵横向压缩试验,对压缩力学性能及破坏模式进行了比较分析。试验结果表明,纵向压缩典型破坏模式为层间基体开裂,横向压缩典型破坏模式为剪切破坏和层间基体开裂;采用环氧树脂基体的试件组较采用乙烯基树脂基体的试件组压缩力学性能有显著提高;提高纵向纤维含量能提高纵向压缩力学性能,但纤维含量过高对于纵向压缩力学性能有不利影响;纤维含量的变化对横向压缩力学性能的影响很小。

Abstract: To investigate the compressive mechanical properties and the failure mechanism of pultruded glass fiber reinforced polymer (GFRP) laminates, matrix resin and fiber mass fraction were regarded as variable parameters, and longitudinal and transverse compression tests were conducted on six kinds of GFRP laminates. Compressive mechanical properties and failure modes were compared and analyzed. The result shows that matrix cracking is the typical longitudinal compressive failure mode, while the typical transverse compressive failure modes are shear failure and matrix cracking. Specimens with epoxy matrix exceled those with vinyl matrix in compressive mechanical properties. Increasing longitudinal fiber mass fraction can improve the longitudinal compressive mechanical properties to a certain extent. But, the fiber with too high mass fraction will have adverse effect. Changing fiber mass fraction has little influence on the transverse compressive mechanical properties.
