Abstract: The fibre-carbon composites developed in Beijing Aeronautical Manufacturing Technology Research Institute have been used for aircraft structural parts. We have analysed dynamic characteristic of some structures made of such kind of material by means of model analysis method and conducted static detections by ultrasonic wave technique, so that we could better comprehend the dynamic characteristics of the fibre-carbon composites, The results of the model analysis is summarised in the paper.

Key words: fibre-carbon composite, model analysis, residues
