摘要
对ＳｉＣｗ／Ａｌ复合材料形变断裂过程中的声发射（ＡＥ）特征的研究表明，用ＡＥ技术能准确测定ＳｉＣ纤维的断裂次数，并能测定其断枝长度，从而测定了纤维和基体间的界面强度和ＳｉＣ纤维的断裂强度．
The model specimen of SiC_w/Al composite is subjected to the tensile test, simultaneously, the acoustic emission (AE) characteristics during the process of strain and fracture are monitered. The broken number of SiC fiber and the segment length of the broken fibers in the composite can be measared by AE technique. The interfacial shear strength and the fractural strength of fiber can be easily determined.
