標題: | Analytical Evaluation of Interfacial Shear Strength for Fiber?Reinforced Ceramic Composites | 作者: | CHUN-HWAY HSUEH | 公開日期: | 1988 | 卷: | 71 | 期: | 6 | 起(迄)頁: | 490-493 | 來源出版物: | Journal of the American Ceramic Society | 摘要: | A methodology is described to evaluate the shear strength at the fiber¡Vcoating interface. Stress analyses are performed for the following system: a fiber with a uniform coating in its central portion which is subjected to an axial tensile stress through its bare ends. The results show that the axial tensile stress in the coating decreases with the increase in the thickness of the coating and that the interfacial shear stress exhibits the opposite trend. Hence, a critical thickness of the coating can be defined depending on the properties of the material, such that when the coating thickness is less than the critical value, failure of the composites initiates from segmentation of the coating during tensile loading. Conversely, when the coating thickness is greater than the critical value, debonding of the interface occurs. Furthermore, the interfacial shear strength can be related to this critical thickness and the tensile strength of the coating. Copyright ? 1988, Wiley Blackwell. All rights reserved |
