Fabrication of Cost Effective Fiber Metal Laminates Based on Jute and Glass Fabrics for Enhanced Mechanical Properties

ABSTRACT

This research focuses on the mechanical behavior of cost-effective novel hybrid fiber metal laminates (FMLs) based on aluminum (Al) 1050 alloy and jute/glass fiber reinforced epoxy composites. The effects of the stacking sequence and relative fiber amounts have been investigated. Specimens were fabricated using hand lay-up technique followed by compression molding. Results revealed that the reinforcement hybridization can potentially improve the tensile and flexural properties of FMLs based on jute fabric. The flexural strength of FMLs based on jute fabric has been improved when partial laminas from jute/epoxy laminate are replaced by glass/epoxy laminas. Also, it is realized that the incorporation of high strength fibers to the composite core leads to higher tensile properties but lower flexural resistance.

摘要

研究了以铝1050合金为基体，黄麻/玻璃纤维/环氧树脂为复合材料的新型复合纤维-金属复合材料的力学性能. 研究了堆积顺序和相对纤维数对纤维长度的影响. 采用手糊技术制作试样，然后进行压缩成型. 结果表明，增强体杂化可以有效地改善黄麻织物基FMLs的拉伸和弯曲性能. 用玻璃/环氧树脂层合板代替部分黄麻/环氧树脂层合板，提高了FMLs的弯曲强度. 此外，人们还认识到，将高强度纤维（即玻璃纤维）掺入复合材料芯中会导致较高的拉伸性能，但弯曲阻力较低.
