簇绒已被证明可以改善复合材料的机械性能。与其他依赖于市售材料的已发表作品不同，对于本研究，使用直径范围为160 μm至720 μm的未填充PPSU和含有1 wt.%的碳纳米管（CNT）使用双螺杆挤出机制备。这些纱线的拉伸性能通常随着CNT的添加在较高的“螺杆速度与牵引”比的值下得到改善。这种效果与纱线拉伸比相关，并归因于在热塑性基体中诱导的纳米填料取向。当加载CNT时，对于相同的参数设置，纤维表现出极限拉伸强度（UTS）增加多达23%。根据填料和加工参数的设置，纱线的UTS从96.4 MPa变化到206.2 MPa的未填充的PPSU和PPSU-CNT，分别。
Tufting has been shown to improve the mechanical properties of composites. Unlike other published works which rely on commercially available materials, for this study, continuous polymer yarns with diameters ranging from 160 μm to 720 μm of unfilled PPSU and PPSU nanocomposites with 1 wt.% of carbon nanotubes (CNT) were prepared using a twin-screw extruder. The tensile properties of these yarns generally improved with the addition of CNT at higher values of ‘screw speed to haul-off’ ratio. This effect is correlated with the yarn draw down ratio and attributed to the nanofiller orientation induced in the thermoplastic matrix. The fibres exhibited as much as a 23% increase in Ultimate Tensile Strength (UTS) for the same parameter set when loaded with CNT. Depending on filler and processing parameters set, yarns varied in UTS from 96.4 MPa to 206.2 MPa for unfilled PPSU and PPSU-CNT, respectively.
