摘要：
In order to analyze the internal structure and the load bearing of layer-to-layer orthogonal angle-interlock woven fabrics and composites, X-ray computed tomography (Micro CT) volume pixels was used to extract non-destructively the internal structure. The micro-structure of layer-to-layer orthogonal angle-interlock the woven fabric was observed by three-dimensional reconstruction, and the twisting and extrusion of monofilaments inside the fabric was observed. The distribution of pores and high-density impurities in the composite were reconstructed and the quantitative estimations were carried out. The results show that the composite demonstrated good integrity after the laminar damage test, there are phenomena shch as pore deformation, delarmination, fiber bending and lamella fractures inside. It was confirmed that the unique structure of the layer-to-layer orthogonal angle-interlock woven fabric effectively improved the interlaminar mechanical properties of the composites, highlighting the importance of nondestructive X-ray computed tomography in analyzing the imaging data of fiber reinforced composites. © 2022 China Textile Engineering Society.
