Abstract

Due to the limitation of manufacturing techniques, voids, low density areas and wrinkle defects inevitably occur during the fabricating process of ceramic matrix composites (CMCs). This study aims to reveal the effect of various defects (voids, low density areas and wrinkle defects) on the tensile strength of plain weave C/SiC composites. The micro-computed tomography (μ-CT) test was used to assess the quantity and distribution of defects within the material. Based on the μ-CT images, finite element models (IB-FEM) of the C/SiC composites with different defect types and contents were reconstructed. The tensile strength of plain weave C/SiC composites containing defects at different temperatures was obtained through experiments and simulations, demonstrating excellent consistency. The effect of different types and contents of defects on the tensile strength of C/SiC composites is investigated and discussed, which is of great significance to enhance understanding of the influence of defects on the mechanical behavior of CMCs.

不同缺陷对C/SiC复合材料抗拉强度的影响：实验和基于图像的有限元分析

由于制造技术的限制，陶瓷基复合材料在制造过程中不可避免地会出现空洞、低密度区和褶皱缺陷。本研究旨在揭示各种缺陷（空隙、低密度区和褶皱缺陷）对平纹织C/SiC复合材料抗拉强度的影响。采用微计算机断层扫描（μ-CT）测试来评估材料内部缺陷的数量和分布。基于μ-CT图像，重建了不同缺陷类型和含量的C/SiC复合材料的有限元模型（IB-FEM）。通过实验和模拟得到了含缺陷的C/SiC平纹织复合材料在不同温度下的抗拉强度，具有良好的一致性。研究和讨论了不同类型和含量的缺陷对C/SiC复合材料抗拉强度的影响，这对深入了解缺陷对复合材料力学行为的影响具有重要意义。

期刊介绍： Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes. Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
