Conducted tests of pipes made of carbonfiber under the influence of cyclic internal pressure with the control of the stress state of straingauges. It was established that if glass-plastic pipes with a diameter of 29 mm and a thickness of 2.5 mm with stand a pressure of 50-60 MPa, then carbon-plastic - up to 130-150 MPa, that is, the strength of carbon-plastic pipes more than 2 times higher. The strength of the modified carbon fiber specimens reaches 130.5 MPa and 159.5 MPa, which is 8.5% higher than the original data The system of automated designing of metal-polymer compounds on the basis of free software is developed.
