摘　　要：高导热C/C复合材料具有高热导率、低密度、低热胀系数和高温下高强度等性能,成为近年来最具发展前景的散热材料之一。本文综述了国内外高导热C/C复合材料的发展现状,分析了C/C复合材料的热物理性能及影响其热导率的因素,介绍了C/C复合材料的导热机理、碳纤维、基体炭的导热性能,以及高导热C/C复合材料的制备和改性等。Carbon/carbon composites are attractive candidates for heat dissipation due to their high thermal con- ductivity, low density, low dilatability and excellent mechanical properties. The paper summaries the research and development of high-thermal conductive C/C composites domestic and overseas, the thermophysical properties of C/C composites and the factors affecting on thermal conductivity are discussed. The thermal conductive mechanism of C/C composites,carbon fibers and matrix carbon are introduced, and the preparation and modification of C/C composites are also recommended.
