Abstract

In this paper, the influence of interphase type (i.e. single-phase (PyC) and co-deposited (PyC+SiC)) and thickness (i.e. 300, 600, 1000, and 2000 nm) on the interface properties and damage evolution of mini-C/SiC composites under cyclic loading/unloading tension was investigated. The micromechanical constitutive model was adopted to derive the damage parameter of inverse tangent modulus (ITM) and perform the hysteresis analysis to estimate the interface properties of the mini-C/SiC composites with large debonding energy. Experimental damage evolution of the ITMs with unloading or reloading stress was analyzed for different interphase types and thickness. The interface properties (e.g. the interface debonding stress and interface debonding energy) were obtained through the hysteresis analysis. Relationships between the loading/unloading ITMs, interface properties, and interphase type and thickness were established.

相间类型和厚度对 C/SiC 复合材料界面特性和拉伸损伤演变的影响

本文研究了在循环加载/卸载拉伸条件下，相间类型（即单相（PyC）和共沉积（PyC+SiC））和厚度（即 300、600、1000 和 2000 nm）对 mini-C/SiC 复合材料界面性能和损伤演化的影响。采用微机械构成模型推导了反切线模量（ITM）的损伤参数，并进行了滞后分析，以估算具有较大脱粘能量的微型 C/SiC 复合材料的界面特性。针对不同的相间类型和厚度，分析了 ITM 在卸载或重载应力作用下的实验损伤演变。通过滞后分析获得了界面特性（如界面脱粘应力和界面脱粘能量）。建立了加载/卸载 ITM、界面特性以及相间类型和厚度之间的关系。
