To meet sustainability objectives in the transport sector, natural fiber (NF) and recycled carbon fiber (RCF) have been developed, although they have been typically limited to low to medium performance components. This work has considered the effect of interlayer hybridization of woven NF and non-woven RCF with woven virgin carbon fibers (VCF) on the mechanical and damping performance of hybrid laminates, produced using double bag vacuum infusion (DBVI). The mean damping ratio of the pure laminates showed a trend of NF>RCF>VCF, which was inversely proportional to their modulus. The tensile, flexural and damping properties of hybrid laminates were dominated by the outermost ply. The VCF-RCF and VCF-NF hybrid laminates showed a comparatively greater mean damping ratio. The results of this work demonstrate a method for the uptake of alternative materials with a minimal impact on the mechanical properties and improved damping performance.
为了实现交通运输部门的可持续发展目标,人们开发了天然纤维(NF)和回收碳纤维(RCF),不过它们通常仅限于低至中等性能的部件。本研究考虑了机织NF和非织造RCF与机织原始碳纤维(VCF)的层间混杂对采用双袋真空灌注(DBVI)生产的混杂层压板的力学性能和阻尼性能的影响。纯层压板的平均阻尼比呈现出NF>RCF>VCF的趋势,这与它们的模量成反比。混杂层压板的拉伸、弯曲和阻尼性能由最外层 ply 主导。VCF-RCF和VCF-NF混杂层压板表现出相对更大的平均阻尼比。这项工作的结果展示了一种采用替代材料的方法,该方法对力学性能影响最小且能改善阻尼性能。
