We give some results of investigation of temperature influence, within 373 К to 77 К interval, on static and dynamic mechanical properties of structure materials to Ье employed with solar arrays of space vehicles. The experimental data thus oЬtained сап Ье used in further theoretical calculations for lifetime of solar arrays under conditions of influence Ьу multiple periodical thermal loads, in the course of orbltal flight.
