Experimental and numerical study of a woven oxide/oxide ceramic matrix composite adhesive joint using four-point bending test

Oxide/oxide ceramic matrix composite materials are now used for applications in hot part of engines. To manufacture some components bonding techniques could be used. In order to understand the possible damage mechanisms of adhesive joint with CMC materials, experimental and numerical analysis using a four-point bending test is presented here. The numerical studies are performed using a continuum damage model for the behavior of the substrate and a cohesive zone model for the behavior of the interface between the composite and the bond. The results of the simulations are presented and discussed.
