| 摘 要： | 用ＳｉＣ单纤维Ａｌ基模型复合材料使断裂源单一化，测定这些断裂源的声发射特征，成功地用声发射特征区分知识复合材料中的纤维断裂，纤维－Ａｌ基体间的界面断裂、基体断裂，结合金相观察，分析了这些断裂产生不同声发射特征的原因。

| Abstract: | Acoustic emission (AE) study on SiC/Al model composite which made the fracture sources simple has been carried out. AE characteristics from fracture sources have been measured. Three kinds of fracture in SiC/Al, fiber fracture, fracture of interface between fiber and matrix and matrix fracture have been recognized and distinguished by AE characteristics. A model proposed based on AE data and metallurgical examination explains the reason of why fracture sources have different AE behaviours. |
