摘要

本研究探讨了通过增材制造（AM）技术连续长丝制造复合材料的动态机械性能。研究人员制作了四种不同纤维取向的尼龙/凯夫拉纤维样品，每种样品的层高为 0.1 毫米，总厚度为 3 毫米，纤维体积分数为 15.71 % 至 18.44 %。采用动态力学分析 (DMA) 评估粘弹性行为，重点是存储模量、损耗模量和阻尼系数（tan delta）。试样 F_NK1 显示出最高的初始存储模量，在较高的沉降温度 (Ts) 下刚度逐渐减小，而 F_NK2 显示出较陡的下降，F_NK3 和 F_NK4 的初始模量较低，温度敏感性较高。

Dynamic mechanical analysis of additively manufactured continuous Kevlar fiber-reinforced nylon composites across variable fiber orientations

This study examines the dynamic mechanical properties of composites made via continuous filament fabrication, an additive manufacturing (AM) technique. Four Nylon/Kevlar samples with varying fiber orientations were produced, each with a 0.1 mm layer height and 3 mm total thickness, resulting in a fiber volume fraction of 15.71 % to 18.44 %. Dynamic mechanical analysis (DMA) was used to assess viscoelastic behavior, focusing on storage modulus, loss modulus, and damping factor (tan delta). The specimen F_NK1 exhibited the highest initial storage modulus, with gradual stiffness loss at higher settling temperatures (Ts), while F_NK2 showed a steeper decline, and F_NK3 and F_NK4 had lower initial moduli and greater temperature sensitivity.
