这表明，拉曼光谱是一个强大的技术分析之间的关系，在高性能纤维的结构和变形过程。简要回顾了仪器的发展，使拉曼光谱变得如此强大的研究。实例给出的应用程序的技术，以遵循不同的芳纶纤维的分子变形过程。它表明，该行为是一致的变形由一个均匀的应力系列型模型，其中变形发生通过晶体拉伸和晶体旋转的组合控制。应力诱导的拉曼带位移是晶体拉伸的直接量度。它进一步表明，聚酯纤维的变形可以用类似的方式来解释。将拉曼技术推广到碳纤维结构与力学性能关系的分析中，再次证明了碳纤维的力学性能与结构有关。
It is demonstrated that Raman spectroscopy is a powerful technique for the analysis of the relationship between structure and deformation processes in high-performance fibres. A brief review is presented of the developments in instrumentation that have enabled Raman spectroscopy to become so powerful for such studies. Examples are given of the application of the technique to follow molecular deformation processes in different aramid fibres. It is demonstrated that the behaviour is consistent with the deformation being controlled by a uniform stress series-type model where deformation takes place through a combination of crystal stretching and crystal rotation. The stress-induced Raman band shifts are a direct measure of crystal stretching. It is further demonstrated that the deformation of polyester fibres can be interpreted in a similar way. The Raman technique is extended to the analysis of the relationship between structure and mechanical properties on carbon fibres where it is again shown that the beh...
