The quality of fiber weave material is highly affected by the fiber orientation. This characteristic becomes obviously when we compare the composite laminates materials in different orientations of the same braiding mode, which leads to the anisotropy of the material mechanical properties. In this work, we propose a concise and efficient method for measuring the fiber orientation on plain weave carbon fiber and 2-D carbon fiber braided composites with angles. Our image acquisition method is making use of the phenomenon that the carbon fiber material has strong light specular reflection, image fusion algorithm perfect the texture of reflective part. Using image processing and computational geometry techniques to calculate the orientation. The results calculated are efficiency for fiber orientations with a remarkably stability. The method was built pure carbon fiber weave, with some small parameters tuning, it can be effectively applied to most plain weave carbon fiber and 2-D carbon fiber braided composites with angles.

纤维编织材料的质量受纤维取向的影响很大。当我们比较相同编织方式的不同方向的复合层压材料时，这种特性变得明显，从而导致材料力学性能的各向异性。在这项工作中，我们提出了一种简洁有效的方法来测量平纹碳纤维和二维碳纤维编织复合材料上的纤维取向。我们的图像采集方法是利用碳纤维材料具有强光镜面反射的现象，图像融合算法完善反射部分的纹理。使用图像处理和计算几何技术来计算方向。计算的结果是具有显着稳定性的纤维取向的效率。
