Characterization and analysis of bundle/matrix interfacial properties in carbon/carbon composites
The bundle/matrix interfacial strength in carbon/carbon composites was evaluated via the fiberbundle pushed-out method. The determined data having a certain difference resulted from different interface fracture behavior via the analyses of the load-displacement curves of the loaded bundles and the observations of SEM images of the pushed-out bundle surface and its bundle/matrix interface. In order to better research bundle/matrix interface properties,Micro-CT was adopted to analyze bundle/matrix interface structure in c/c composites with nondestructive method,and its 2D and 3D images of real interfacial structure were obtained. Thus,the bundle pushed-out method,SEM and Micro-CT are better analysis and characterization methods of interfacial properties at bundle/matrix interface.
