Summary

In the 1373–1523K domain, the creep behavior of SiCfSiBC batches tested under argon and 120 MPa has been investigated. The creep deformation of these composite is governed by a damage creep mechanism : first the creation of matrix microcracking until its saturation, then an opening of the microcracks in the transverse tows. Depending on the experimental conditions, the SiCf fibers which bridges the cracks can also creep.
