Development of weaving technology for manufacturing three-dimensional spacer fabrics with high-performance yarns for thermoplastic composite applications: An analysis of two-dimensional mechanical properties

摘要

This article focuses on the improved strength and stiffness of woven three-dimensional (3D) spacer fabrics used in fiberreinforcednplastics. The spacer fabrics were manufactured using E-glass/polypropylene (GF/PP) hybrid yarns and arenintended for lightweight engineering applications. The two-dimensional (2D) woven fabrics used for the outer layers ofn3D spacer fabrics were produced from GF/PP hybrid yarns with different yarn alignments and weft densities.nFurthermore, the implemented hybrid yarns and the 2D composites constructed of multi-layer fabrics were testednfor mechanical properties. The processing of the GF/PP hybrid yarn, as well as the geometry of the woven fabrics, isnproven to strongly influence the mechanical properties of the end composites. Multi-layer fabrics can be used fornmanufacturing woven 3D spacer fabrics with minimal yarn damage and high mechanical properties.
