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 fiber-bundle 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.
