A multi-scale stochastic model for damage analysis and performance dispersion study of a 2.5D fiber-reinforced ceramic matrix composites

•A framework of multi-scale stochastic model is established with Monte-Carlo method.•A full-thickness RVE model is established based on the material weave architecture.•Damage analysis and performance distribution of a 2.5D woven composite were studied.•Dispersion transport analysis between different scales was studied.
