Abstract

Tyranno SA4 grade SiC fiber is an emerging continuous fiber with excellent mechanical properties. The origin of the fiber's high-performance was studied by comparative Raman spectroscopy of four different grades of SiC fibers and reference SiC monolith. Analysis of the Raman spectra of fiber cross-sections, surface and homogeneity, and fibers under stress, revealed how differences in microstructure, such as crystalline order, size, and the presence of critical flaws, dictate mechanical properties. This information can help optimize SiC fiber manufacturing.

用比较拉曼光谱研究高强度Tyranno SA4 SiC纤维的显微结构来源

Tyranno SA4级SiC纤维是一种具有优异机械性能的新兴连续纤维。通过对比四种不同等级的SiC纤维和参考SiC整体体的拉曼光谱，研究了该纤维高性能的来源。对纤维横截面、表面和均匀性以及应力下纤维的拉曼光谱进行分析，揭示了微观结构（如晶体顺序、尺寸和关键缺陷的存在）的差异如何决定力学性能。这些信息可以帮助优化SiC纤维的制造。
