Increase in mass efficiency of designs of aircraft, due to application of three-layer cellular elements from composite materials
This work is devoted to search of ways of increase in mass efficiency of designs of frameworks of spacecraft’s for the purpose of removal into an orbit of systems with the maximum payload. One of solutions of this problem is application of glued cellular frameworks from composite materials, namely coal plastics. Within this work the three-layer designs applied in production of aircraft and the missile and space equipment, their advantage and shortcomings are considered. The manufacturing techniques of details from a coal plastic are described; on the basis of experimental data the material choice is reasonable.
