Aerospace Instrument-Making Annotation << Back METHOD OF RELAXATION OF RESIDUAL STRESSES IN COMPOSITE ELASTIC ELEMENTS OF SPACE ARCHITECTURAL STRUCTURES I.I. Dementev, A.N. Ustinov In the space industry of the Russian Federation, there is a tendency to replace metal alloys used in the production of elastic structural elements (UEC) of spacecrafts, fibrous composite materials. The disadvantages of composites are technological stresses arising in semi-fi nished products of UEC, while ensuring the adhesion of substances of reinforcing components and matrices. The article presents a new way to reduce the technological residual stresses acting in composites after the production cycles are completed. Key words: spacecraft, composite elastic element; technological stresses; relaxation of residual stresses; controlled heat treatment using controlled vibration loads.
