Abstract

This study modified basalt fibers (BFs) by cyclic soaking and drying in an aqueous carbon nanotube (CNT) dispersion. Melt mixing was employed to prepare the unmodified and modified 10 wt% BFs reinforced nylon 6 (PA6) composites, which were subsequently granulated for fused granular fabrication (FGF) 3D printing. The results showed that the CNT content on the fiber surface increased with increased modification time. The warping degree of 3D-printed samples was reduced significantly by adding BFs. The results of thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) showed that adding BFs improved the thermal stability and crystallization temperature of PA6. The samples' tensile and flexural properties were remarkably enhanced by the CNT modification of BFs. The mechanical properties of 3D-printed and hot-pressed samples were in close approximation, indicating a robust interfacial interaction between modified BFs and the PA6 matrix. At the modification time of 45 min, the BF/PA6 composite with 0.04 wt% CNTs demonstrated excellent mechanical properties and wear resistance. Compared with PA6 and unmodified composites, the modified composite's tensile strength was increased by 122.5 % and 44.6 %, and the friction coefficient was reduced by 36.1 % and 33.4 %, respectively.

碳纳米管改性玄武岩纤维/尼龙6复合材料的3D打印及性能研究

研究了在碳纳米管（CNT）水相分散体系中循环浸泡和干燥改性玄武岩纤维（BFs）。采用熔体混合制备未改性和改性10 wt% bf增强尼龙6 （PA6）复合材料，随后将其造粒，用于熔融颗粒制造（FGF） 3D打印。结果表明：改性时间越长，纤维表面碳纳米管含量越高；添加bf后，3d打印样品的翘曲程度明显降低。热重分析（TGA）和差示扫描量热分析（DSC）结果表明，BFs的加入提高了PA6的热稳定性和结晶温度。纳米碳纳米管改性后，样品的拉伸和弯曲性能得到了显著提高。3d打印和热压样品的力学性能非常接近，表明改性bf与PA6基体之间存在强大的界面相互作用。当改性时间为45 min时，0.04 wt% CNTs的BF/PA6复合材料表现出优异的力学性能和耐磨性。与PA6和未改性的复合材料相比，改性后的复合材料抗拉强度分别提高了122.5%和44.6%，摩擦系数分别降低了36.1%和33.4%。

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
