| 摘 要： | 以丙烯腈-丁二烯-苯乙烯(ABS)为基体，以HGB、GF、ZnO、TiO和Al2O3为改性填料，制备五种改性ABS复合材料，进而利用熔融沉积成型(FDM)3D技术打印复合材料试件，测定试件的力学性能，并绘制应力应变曲线，然后进行不同改性材料拉伸强度、杨氏模量及断裂伸长率等力学性能分析。结果表明，与纯ABS材料相比，HGB的填充会导致ABS试件杨氏模量增加，但拉伸强度和断裂伸长率降低；GF的填充能够同时增加ABS试件的拉伸强度、杨氏模量及断裂伸长率；ZnO、TiO及Al2O3等纳米颗粒的填充均使ABS试件的拉伸强度、杨氏模量和断裂伸长率增强，其中TiO对ABS拉伸强度的增强效果最好，拉伸强度增加高达35.33%。

| Abstract: | Using acrylonitrile-butadiene-styrene (ABS) as matrix and HGB, GF, ZnO, TiO and Al2O3 as modified fillers, five different modified ABS composites were prepared. Then, the modified ABS material specimens were printed using FDM 3D printer and the mechanical properties of specimens were measured. According to the measured results, their stress-strain curves were drawn, and the effect of the different fillers on the mechanical properties of ABS-printed specimens were compared and analyzed in detail. Findings show that, compared with pure ABS, the addition of HGB improves Young′s modulus of ABS-printed specimens, but there is a decrease in the tensile strength and elongation at break. The filling of GF increases the tensile strength, Young′s modulus and elongation at break of ABS. The filling of ZnO, TiO and Al2O3 nano-particles can significantly increase the tensile strength, Young′s modulus and elongation at break of ABS than GF, and the filling of TiO has the most significant effect on increasing the tensile strength of ABS and an increase of 35.33% in tensile strength is obtained by the filling of TiO. |
