分别以氧化石墨粉(GO)、还原氧化石墨烯乙醇悬浮液(RGO)和热法还原石墨烯粉(TRG)为填料,分散于酚醛树脂(PR)的乙醇溶液中,再将这些基体混合物涂覆于炭纤维(CF)布上,经热压成型工艺制备氧化石墨烯/酚醛树脂/炭纤维、还原氧化石墨烯乙醇悬浮液/酚醛树脂/炭纤维、热法还原氧化石墨烯/酚醛树脂/炭纤维层次复合材料.研究了GO、RGO和TRG对复合材料结构、压缩性能、弯曲性能及磨擦性能的影响.结果表明,与纯酚醛树脂/炭纤维复合材料相比,当纳米填料的质量分数仅为0.1％时,层次复合材料的压缩性能可显著提高,其中,热法还原氧化石墨烯/酚醛树脂/炭纤维的压缩强度和模量分别提高了178.9％,129.5％；弯曲性能也可得到一定的改善.还原氧化石墨烯乙醇悬浮液/酚醛树脂/炭纤维层次复合材料的最大储能模量可提高75.2％.所有改性石墨烯/酚醛树脂/炭纤维层次复合材料的Tg均有所降低.
