Abstract Dealing with the « French Supersonic Aircraft Research Program», thermal cycling tests in four environments, neutral (vacuum, nitrogen) and oxidative (air, oxygen), were performed on carbon/epoxy cross ply laminates [0 3 /90 3 ] S . This experimental study was conducted following a local approach through optical and scanning electron microscopy observations and X radiographs and showed a significant effect of the oxygen level on the damage development. Moreover, coefficient of moisture expansion (CME) tests were performed on the same material to characterize the influence of moisture on the sample expansion.
