In comparison with the carbonized fibers, the carbon fibers after graphitization treatment display more perfect crystal orientation along the main surface of ribbon-shaped carbon fibers. 与炭化处理纤维相比,石墨化纤维晶体结构更加完整,沿纤维主表面的取向程度更高。
Study on the preparation of ribbon-shaped mesophase pitch-based fibers and infusible 带形中间相沥青纤维的制备与不熔化研究
Preparation and properties of mesophase pitch-based ribbon-shaped carbon fibers 中间相沥青基条形炭纤维的制备与性能
It takes advantage of precipitation strengthening and ribbon-shaped in-situ composite phases to increase the longitudinal strength with little influences on conductivity, which fulfilled the requirements of both strength and conductivity at lower cost. 该材料利用析出强化和层片状原位复合增强相来提高纵向强度,同时对导电性能影响很小,能以较低的成本满足强度及导电性要求。
Multi-dimensional analysis reduces the correlation among the signal components after wavelet transform, and the auto-correlative matrix represents sparse ribbon-shaped distribution. 小波变换可以建立信号的多分辨分析,这使经过小波变换后的信号分量间的相关性降低,且其自相关矩阵呈现特殊的稀疏带状分布。
