Abstract
Carbon or graphite tubes which are mutually connected by an adhesive connection are less stressable than individual tubes. A sleeve formed of fibers and impregnated with a thermoplast is pulled onto the connection position. The new connection increases the stressability of connected tubes. The thermoplast limits the build up of stressing so that the reduction factor of the strength of the connection amounts only to 10 to 15%.
