Abstract

The subject of this study are tribological and strength properties of composites with matrix material in the form of thermoplastic plastics and a reinforcing material in the form of carbon fibers used in 3D printing technology—Fused Deposition Modeling. Simulation results of matrix material flow in the nozzle are presented. An analysis of the matrix material mixing process in the designed system was carried out and we developed our own conclusions. The article presents the method of forming this type of composite using a printhead at the stage of fabrication of an element. The possibility of modifying the geometrical distribution of reinforcing fibers in an element of the composite being tested by modifying the height of the layer of the applied material has been demonstrated. The relationship between the distance of subsequent carbon fiber bundles and the assumed height of the layer of applied material has been presented. Test results of abrasive wear and tensile strength of obtained materials with different percentages of reinforcing fibers are presented.

熔融沉积成型ABS / CF纤维复合材料的摩擦学和强度性能研究

摘要

本研究的主题是3D打印技术（熔融沉积建模）中具有热塑性塑料形式的基体材料和碳纤维形式的增强材料的复合材料的摩擦学和强度特性。给出了喷嘴中基体材料流动的模拟结果。在设计的系统中对基质材料的混合过程进行了分析，我们得出了自己的结论。该文章提出了在元件制造阶段使用打印头形成这种复合材料的方法。已经证明了通过改变所施加的材料层的高度来改变增强纤维在被测复合材料中的几何分布的可能性。已经提出了随后的碳纤维束的距离与所施加的材料层的假定高度之间的关系。给出了具有不同百分比的增强纤维的所得材料的磨料磨损和拉伸强度的测试结果。
