On the basis of a pilot study of samples of composite material mark- КМКУ-2М.120.Э01. provided a chart of this material stretching, as well as identified the loss of its strength in the presence of the concentrator in the form of holes. Theoretical and experimental studies were also carried out to assess the reduction of the static strength of this composite, extension test with impact damage with different energy of low-speed blow. All calculations were performed by the method of finite elements. Also was made assessment of the dependence of loss of strength from impact energy on the criterion of an equivalent hole. The results are compared with experimental and based on this may be deemed reliable.
