碳纤维的特点是重量轻，拉伸强度和拉伸模量非常高，在2000°C以上的温度下也能保持。这些特性使碳纤维成为轻质复合材料的理想候选者，特别是用于高温航空航天应用。碳纤维的微观结构在不同的长度尺度上具有几个独特的特征，这些特征都是基于石墨烯片的堆叠及其相互取向。本章概述了碳纤维结构的现有知识，纤维生产和加工过程中的操作，以及结构如何决定纤维性能。
Abstract Carbon fibres are characterised by low weight and very high values of tensile strength and tensile modulus, which are maintained up to temperatures well above 2000°C. These properties make carbon fibres ideal candidates for lightweight composites, in particular for high temperature aerospace applications. The microstructure of carbon fibres is characterised by several peculiar features at different length scales, which are all based on the stacking of graphene sheets and their mutual orientation. This chapter provides an overview about the current knowledge of carbon fibre structure, its manipulation during fibre production and processing, and how the structure determines fibre properties.
