In this work, poly(acrylonitrile‐butadiene‐styrene) (ABS) filaments containing 0, 1, 3, and 5 wt% multi‐walled carbon nanotubes (MWCNT) were prepared by extrusion. The filaments were then used to make the required specimens with a fused deposition modeling machine. The results obtained from the tensile measurements revealed that with the increase in the layer thickness, the tensile strength of the printed specimens decreased; however, the raster angle did not have any significant effect on the properties. The transmission electron microscope images showed that for the sample containing 3 wt% MWCNT, nanoparticles were reasonably dispersed throughout the matrix. The scanning electron microscope images illustrated that the size of the voids formed within the specimens was increased with increasing of the layer thickness from 0.05 to 0.2 mm. It was also found that the maximum properties could be obtained by using the layer thickness, raster angle and MWCNT concentration of 0.05 mm, 45/−45°, and 3 wt%, respectively. The results showed that both the tensile strength and elastic modulus of the filaments progressively increased with the increase of the nanofiller content in the range studied. It was found that for the constant layer thickness of 0.05 mm, all the specimens printed with single raster angles of 0, 45, and 90° showed higher tensile strength in comparison with their counterparts printed with two raster angles of 0/90° and 45/−45°.

熔融沉积模拟制备的聚丙烯腈-丁二烯-苯乙烯/多壁碳纳米管纳米复合材料样品的形貌和力学性能

在这项工作中，通过挤压制备了包含0、1、3和5 wt％的多壁碳纳米管（MWCNT）的聚（丙烯腈-丁二烯-苯乙烯）（ABS）长丝。然后，将这些细丝通过熔融沉积成型机用于制作所需的样品。拉伸测量的结果表明，随着层厚度的增加，印刷样品的拉伸强度降低。但是，光栅角对性能没有任何显着影响。透射电子显微镜图像显示，对于包含3wt％MWCNT的样品，纳米颗粒合理地分散在整个基质中。扫描电子显微镜图像表明，随着层厚度从0.05mm增加到0.2mm，在样品内形成的空隙的尺寸增加。还发现最大性能可以通过分别使用0.05mm，45 / -45°和3wt％的层厚度，光栅角和MWCNT浓度获得。结果表明，在所研究的范围内，长丝的拉伸强度和弹性模量都随着纳米填料含量的增加而逐渐增加。发现对于恒定厚度为0.05 mm的样品，与以0/90°和45的两个光栅角印刷的样品相比，以0、45和90°的单个光栅角印刷的所有样品均显示出更高的拉伸强度。 / −45°。结果表明，在所研究的范围内，长丝的拉伸强度和弹性模量都随着纳米填料含量的增加而逐渐增加。发现对于恒定厚度为0.05 mm的样品，与以0/90°和45的两个光栅角印刷的样品相比，以0、45和90°的单个光栅角印刷的所有样品均显示出更高的拉伸强度。 / −45°。结果表明，在所研究的范围内，长丝的拉伸强度和弹性模量都随着纳米填料含量的增加而逐渐增加。发现对于恒定厚度为0.05 mm的样品，与以0/90°和45的两个光栅角印刷的样品相比，以0、45和90°的单个光栅角印刷的所有样品均显示出更高的拉伸强度。 / −45°。
