测量的碳纤维无卷曲三维正交编织复合材料的内部几何形状，包括。纱线的波度、纱线的横截面、纱线横截面的尺寸和局部纤维体积分数。经纱和纬纱的波度测量值远低于0.1%。这表明，这里称为”非卷曲”的织物在生产时具有几乎直的面内纤维，并且在经历织物处理和复合材料制造的所有步骤之后保持该特征。纱线尺寸的变化性对于经纱和纬纱方向在4-8%的范围内，而纱线间距的变化性在3- 4%的范围内。这些可变性参数低于在典型的碳2D编织和3D互锁编织复合材料中纱线波纹度和横截面尺寸的可变性的相应范围，这也在本工作中示出用于比较。
Measurements of the internal geometry of a carbon fiber non-crimp 3D orthogonal woven composite are presented, including. waviness of the yarns, cross sections of the yarns, dimensions of the yarn cross sections, and local fiber volume fraction. The measured waviness of warp and fill yarns are well below 0.1%. which shows that the fabric termed here" non-crimp" has nearly straight in-plane fibers as-produced, and this feature is maintained after going through all steps of fabric handling and composite manufacturing The variability of dimensions of the yarns is in the range of 4-8% for warp and fill directions, while the variability of the yarn spacing is in the range of 3-4%. These variability parameters are lower than respective ranges of variability of the yarn waviness and the cross-sectional dimensions in typical carbon 2D weave and 3D interlock weave composites, which are also illustrated in this work for comparison.
