中文摘要：

采用改性酚醛树脂为粘结剂,连续碳纤维和短切纤维为增强相,铜为导电相,石墨为润滑相,利用热压技术制备碳纤维增强受电弓滑板。对试样进行电阻测试、冲击试验以及磨损试验,利用SEM对冲击断面和磨损形貌进行观察。结果表明,连续碳纤维增强滑板的冲击性能和耐磨性明显优于短切纤维增强滑板;碳纤维含量对滑板的机械性能影响较大;纤维与树脂界面结合良好;受电弓滑板在摩擦过程中最主要的机械磨损形式是磨粒磨损、粘着磨损和氧化磨损。

英文摘要：

The carbon fibre reinforced pantograph sliding plates were fabricated by heated pressing,with modified phenolic resin as bonder,the continuous carbon fibre/short fibre is a reinforcing phase,the copper is electric conductive phase and graphite is lubricating phase.The impact toughness,electric resistance and wear resistance of the slide plate were tested.Wear surface and impact fracture were examined by scanning electron microscope（SEM）.The results show that the continuous carbon fibre reinforced pantograph sliding plate has superior impact toughness and wear resistance than that of short carbon fibre reinforced one.Mechanical properties are largely affected by carbon fibre fraction.The interface bond between fibre and resin is good.In addition,adhesion wear,abrasive wear and oxidation wear are the main wear form of pantograph slide plates.
