The reinforcements of nanoparticles have an important role in improving the machinability of nanocomposite materials. Except for the known nanoparticles such as carbon nanotube, graphene, nanoclay, etc., the effect of boron nitride reinforcement on the machinability of composite materials are a recent research topic. In this study, boron nitride nanoparticle was introduced to the matrix resin that brings about additional strength and enhancement in thermal and mechanical properties of the composite. Though it was confirmed that this composition enhances the focused properties, it is necessary to investigate drilling performance of these composite and identify the effects of this boron nitride nanoparticle on machinability of carbon fiber epoxy nanocomposite considering thrust force, delamination factor, etc. Accordingly, while the thrust force is increased by reinforcement of the boron nitride nanoparticles, on the contrary of literature, delamination factor is tend to reduce as compared with reference composite. This experimental study shows the addition of boron nitride nanoparticles help to reduce delamination factor of carbon fiber epoxy nanocomposite. In addition, hole surfaces and drilling mechanism analyzed with optical and scanning electron microscope about damage estimation.

氮化硼纳米颗粒对钻孔碳纤维环氧纳米复合材料分层的评价

纳米粒子的增强在改善纳米复合材料的可加工性方面具有重要作用。除了碳纳米管、石墨烯、纳米粘土等已知纳米粒子外，氮化硼增强对复合材料可加工性的影响是最近的研究课题。在这项研究中，氮化硼纳米颗粒被引入到基体树脂中，从而增加了复合材料的强度和热性能和机械性能。尽管已证实该组合物增强了聚焦性能，但有必要研究这些复合材料的钻孔性能，并确定该氮化硼纳米颗粒考虑推力、分层因素等因素对碳纤维环氧纳米复合材料的可加工性的影响。因此，虽然通过氮化硼纳米颗粒的增强增加了推力，但与文献相反，与参考复合材料相比，分层因子趋于降低。本实验研究表明，氮化硼纳米颗粒的加入有助于降低碳纤维环氧纳米复合材料的分层因子。此外，利用光学和扫描电子显微镜对孔表面和钻孔机理进行了损伤估计分析。
