Damage Detection in Fibre Reinforced Ceramic and Metal Matrix Composites by Acoustic Emission
In this work damage micro-mechanisms of two different types of fibre reinforced composites are investigated by acoustic emission,AE.Ceramic based oxide fibre reinforced mullite matrix composite and metallic based SiC fibre reinforced titanium matrix composites exhibit different fracture mechanisms during loading and AE technique could pinpoint these damage mechanisms based on the AE responses detected simultaneously.The results show that in a ceramic matrix composite,the identification of fibre fracture and matrix cracking requires careful analysis of the AE data as both fibres and matrix break in brittle manner.Whereas the separation of fibre fracture from the ductile tearing of matrix ligaments could be easier in metallic based composites,such as titanium matrix composites.
