The paper describes impulse deformation of tubes made of partially polymerized carbon filled plastic in combination with aluminium rings. A mathematical model is proposed for investigation of two stages of joint deformation. The first stage involves impulse deformation of an aluminium ring combined with carbon filled plastic mass. During the second stage the kinematics obtained at the first stage is used to determine the stress-strain state of a carbon filled plastic tube by the finite-element method. Changes in the stress-strain state due to a number of technological parameters are also described.
