摘要

便携式电子产品的快速发展需要一种具有卓越耐磨性能的多功能复合材料。优异的耐磨性对于防止层压材料在恶劣的工作条件下提前失效至关重要。因此，制造具有优异抗磨损性能的新型材料是即将推出的集成设备的首要目标。通过摩擦试验评估了复合材料的摩擦系数（COF）和特定磨损率（Ws）。使用原子力显微镜和场发射扫描电子显微镜对磨损表面进行了分析。混合填料的加入改善了相应复合材料的磨损性能。与 CFRP 复合材料相比，BN（60%）-ZrO2（40%）/碳纤维/环氧树脂复合材料的 COF 和 Ws 分别降低了 56% 和 92%，有利于多功能热界面的应用。

Effect of 3D interconnected Zr-BN based hybrid filler on the tribological properties of carbon fiber reinforced epoxy composites

The rapid growth of portable electronics requires a multifunctional composite with superior wear capability. Exceptional wear resistance is crucial for preventing early failure of laminated materials in harsh operating conditions. Hence, fabricating novel materials with excellent anti-wear performance is the primary objective in forthcoming integrated devices. The coefficient of friction (COF) and specific wear rate (W_s) of the fabricated composites were evaluated by tribo-test. The worn surface was analyzed using atomic force microscopy and field emission scanning electron microscopy. Incorporating the hybrid filler improved the wear performance of the corresponding composites. Compared to the CFRP composite, the COF and W_s of BN (60 %)-ZrO₂(40 %)/carbon fiber/epoxy composite were reduced by ∼56 % and 92 %, benefiting multifunctional thermal interface applications.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
