FRA1Fabrication of a composite material
An interphase coating is formed by chemical vapor infiltration CVI on the fibers constituting a fibrous preform the interphase coating comprising at least one inner layer of defrosting of the composite material in contact with the fibers and a outer layer of adhesion with the ceramic matrix The fiber preform is then held in shape with the fibers provided with the interphase coating and

Chat OnlineFatigue of ceramic matrix compositesScienceDirect
Mar 01 1995 Fatigue in ceramic matrix composites typically occurs when matrix cracks are present It proceeds by cyclic degradation of the sliding resistance of the interface The basic mechanisms are discussed and a methodology is developed that enables fatigue life predictions to be made based on a minimum number of experimental measurements.
