Interfacial Shear Behavior of Two Titanium-Based SCS-6 Model Composites

摘要: Single fiber push-out and push-back tests combined with acoustic response monitoring were used to examine the interfacial behavior in two titanium alloy-SiC composites. Distinctly different behaviors observed systems. The differences attributed formation of a substantial reaction layer one composites which changed chemistry resulting debond topography. caused an increase bond strength roughness debonded interface. latter resulted substantially increased sliding friction. Although both composite interfaces exhibited some roughness, only showed seating drop during push-back. This is related fact that formed was severely degraded pushout. this interface still rough, correspondence between matrix destroyed sliding, such no longer possible.
