The analysis of failure process of carbon fiber reinforcement plastic (CFRP) samples under tension load is given. For a visual representation of the results of preliminary calculations, samples' failure set with different layers loads and different reinforcement lay-up is given. CFRP samples were loaded gradually up to the loads at which the failure process begins and develops. In order to visualize the volume microstructure of the samples the acoustic microscopy data which was carried out after each stage of sample loading is given. The research of the dynamic structure failure process in samples shows that the calculation method was used is correct and that the diagnosing of the failure process in carbon fiber samples at different stages by using methods of acoustic microscopy is possible.
