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.

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.
