This study evaluated the properties of 3D-printed Onyx-fiberglass composites. These composites were 3D-printed with zero, one, two, three, and four layers of fiberglass. Ten samples of each configuration were printed for the tensile and flexural tests. The average tensile strength of the Onyx specimens was calculated to be 44.79 MPa, which increased linearly by approximately 20-25 MPa with each additional fiberglass layer. The elastic moduli calculated from the micromechanics models were compared with the experimental values obtained from the tensile tests. The experimental elastic modulus increased more significantly than the model prediction when more fiberglass layers were added. The flexural modulus of Onyx was 17.6 GPa, which increased with each additional fiberglass layer. This quantitative analysis of composites fabricated using 3D printing highlights their potential for commercialization and industrial applications.
本研究评估了3D打印的玛瑙-玻璃纤维复合材料的性能。这些复合材料是用零层、一层、两层、三层和四层玻璃纤维进行3D打印的。每种结构打印十个样本用于拉伸和弯曲测试。玛瑙样本的平均拉伸强度经计算为44.79兆帕,每增加一层玻璃纤维,其强度线性增加约20 - 25兆帕。将根据微观力学模型计算出的弹性模量与拉伸试验获得的实验值进行比较。当添加更多玻璃纤维层时,实验弹性模量的增加比模型预测更显著。玛瑙的弯曲模量为17.6吉帕,随每增加一层玻璃纤维而增加。这种对使用3D打印制造的复合材料的定量分析突出了它们在商业化和工业应用方面的潜力。
