Creation of Ultra-light Spacecraft Constructions Made of Composite Materials

The problem of creating ultra-light composite structures is considered. An overview of the main modern methods of manufacturing composite materials and methods of increasing the weight efficiency of constructions in view of the structure destination, its force work and operating conditions are given. The main design and technological solutions to reduce the weight of a regular construction zone, connection zone and transition zone are offered. The importance of taking into account the anisotropy of mechanical and thermo-elastic properties of composite materials for structures with special requirements for dimensional stability is noted. Guidelines for choice of materials components and manufacturing technology depending on the design application, operating conditions and the nature of load distribution are given. Examples create ultralight structures and their properties are given.
