ABSTRACT

Mechanical properties of flax/basalt/E-glass fibers reinforced epoxy composites were studied in this paper. Vacuum bagging technique was adopted for the fabrication of hybrid composite laminates. The effects of fibers relative amounts and stacking sequence on the tensile, flexural and impact properties were investigated. Results showed that the developed hybrid composites display enhanced tensile, flexural, and impact performance as compared to flax fiber/epoxy composite. The tensile, flexural, and impact strengths increase when partial laminas from flax fiber/epoxy laminate are replaced by basalt and/or glass fiber reinforced epoxy laminas. Incorporating high strength fibers to the composite outer layers leads to improved flexural and impact resistances, whilst the opposite was noticed for tensile properties. The fabricated hybrids show economical and specific mechanical properties benefits. Fibers relative amounts and stacking sequence have noticeable effects on the studied mechanical properties.

摘要

本文研究了亚麻/玄武岩/E-玻璃纤维增​​强环氧树脂复合材料的力学性能。采用真空袋装技术制备混合复合层压板。研究了纤维相对量和堆叠顺序对拉伸、弯曲和冲击性能的影响。结果表明，与亚麻纤维/环氧树脂复合材料相比，开发的混合复合材料显示出增强的拉伸、弯曲和冲击性能。当来自亚麻纤维/环氧树脂层压板的部分层被玄武岩和/或玻璃纤维增​​强环氧树脂层代替时，拉伸、弯曲和冲击强度增加。在复合材料外层中加入高强度纤维可提高抗弯曲性和抗冲击性，而拉伸性能则相反。制造的混合动力车显示出经济和特定的机械性能优势。纤维相对量和堆叠顺序对研究的机械性能有显着影响。
