碳纤维（carbon fiber，简称CF），是一种含碳量在95%以上的高强度、高模量纤维的新型纤维材料。它是由片状石墨微晶等有机纤维沿纤维轴向方向堆砌而成，经碳化及石墨化处理而得到的微晶石墨材料。碳纤维“外柔内刚”，质量比金属铝轻，但强度却高于钢铁，并且具有耐腐蚀、高模量的特性，在国防*工和民用方面都是重要材料。它不仅具有碳材料的固有本征特性，又兼备纺织纤维的柔软可*性，是新一代增强纤维的。碳纤维具有许多优良性能，碳纤维的轴向强度和模量高，密度低、比性能高，无蠕变，非氧化环境下耐超高温，耐疲劳性好，比热及导电性介于非金属和金属之间，热膨胀系数小且具有各向异性，耐腐蚀性好，X射线透过性好。良好的导电导热性能、电磁屏蔽性好等。碳纤维与传统的玻璃纤维相比，杨氏模量是其3倍多；它与凯夫拉纤维相比，杨氏模量是其2倍左右，在有机溶剂、*、碱中不溶不胀，耐蚀性突出。

用途：碳纤维是发展国防*工与国民经济的重要战略物资，属于技术密集型的关键材料，随着从短纤碳纤维到长纤碳纤维的学术研究，使用碳纤维制作发热材料的技术和产品也逐渐普及。在当今世界高速工业化的大背景下，碳纤维用途正趋向多样化。中国已经有使用长纤作为高性能纤维的一种，在要求高温，物理稳定性高的场合，碳纤维复合材料具备不可替代的优势。[ 材料的比强度愈高，则构件自重愈小，比模量愈高，则构件的刚度愈大，正是由于兼具优异性能，碳纤维在国防和民用领域均有广泛的应用前景。

碳纤维的主要用途是与树脂、金属、陶瓷等基体复合，制成结构材料。碳纤维增强环氧树脂复合材料，其比强度、比模量综合指标，在现有结构材料中是最高的。在密度、刚度、重量、疲劳特性等有严格要求的领域，在要求高温、化学稳定性高的场合，碳纤维复合材料都颇具优势。碳纤维是50年代初应*、宇航及航空等尖端科学技术的需要而产生的，现在还广泛应用于体育器械、纺织、化工机械及*学领域。随着尖端技术对新材料技术性能的要求日益苛刻，促使科技工作者不断努力提高。80年代初期，高性能及超高性能的碳纤维相继出现，这在技术上是又一次飞跃，同时也标志着碳纤维的研究和生产已进入一个高级阶段。
