Investigation on the Properties of 3D Warp Interlock Fabrics Based on Moroccan Sisal Yarns as Reinforcement for Composite Materials

ABSTRACT

Despite the variability of Moroccan natural resources, few Moroccan natural fibers are exploited as natural textile composites. This study aims to investigate the characteristics of 3D warp interlock fabrics based on Moroccan sisal yarns. Before weaving, the characteristics of sisal yarns have been analyzed following standards. Based on these natural yarns, six different 3D fabric architectures were manufacturing on the same manual dobby loom. During the weaving process, process parameters have been kept constant for all the 3D woven architectures to ensure a similar value for both the warp and weft yarn densities. Different values of the fabric areal density and thickness of 3D fabrics have been measured under the same test and related conditions. Different parameters play an important role on these different product parameter values as; the non-regularity of the yarn and the significant differences of warp and weft shrinkages depending on the 3D woven architecture. At the same time, yarn damage has been checked before and after the weaving of the produced 3D woven preforms. At the end of this study, new knowledge on the mechanical performance of 3D warp interlock sisal fabric have been revealed for facilitating the suited choice of architecture for a composite material solution.

摘要

尽管摩洛哥的自然资源多种多样，但很少有摩洛哥天然纤维被用作天然纺织复合材料. 本研究旨在探讨以摩洛哥剑麻纱线为原料的三维经纱互锁织物的特性. 在织造前，按照以下标准对剑麻纱线的特性进行了分析. 基于这些天然纱线，在同一台手动多臂织机上制造了六种不同的三维织物结构. 在织造过程中，所有三维机织结构的工艺参数都保持不变，以确保经纱和纬纱的密度值相似. 在相同的试验条件下，测量了三维织物的不同面密度和厚度值. 不同的参数对这些不同的产品参数值起着重要的作用; 纱线的不规则性和经纬收缩的显著差异取决于三维机织结构. 同时，对生产的三维机织预制件在织造前后的纱线损伤情况进行了检测. 在这项研究的最后，对三维经纱剑麻织物的力学性能有了新的认识，有助于为复合材料解决方案选择合适的结构.
