The project aims to establish the potential of naturally occurring halloysite nanotubes [Al2(OH)4Si2O5(2H2O)] as a novel reinforcement for structural polyamide-6 nanocomposites prepared by twin-screw extrusion, containing both as-received as well as chemically-modified non-carbon nanotubes. Varying degrees of filler and molecular orientation are induced by injection-moulding of specimens with a different thickness as well as by direct fibre melt-spinning. Taking into account the expected variations in nanocomposite microstructure, the reinforcement capability of the halloysite nanotubes is compared to that observed for standard clay or carbon-based nanoparticles.

该项目旨在确定天然埃洛石纳米管[Al 2（OH）4Si 2 O 5（2 H2O）]作为双螺杆挤出制备的结构聚酰胺-6纳米复合材料的新型增强材料的潜力，该复合材料包含原样以及化学改性的非碳纳米管。不同程度的填料和分子取向诱导注塑成型的试样具有不同的厚度，以及通过直接纤维熔融纺丝。考虑到纳米复合材料微观结构的预期变化，埃洛石纳米管的增强能力与标准粘土或碳基纳米颗粒所观察到的增强能力进行比较。
