Abstract: Designing issues of optical telescope stable-size composite elements have been considered. Staging of design calculation for composite structural elements has been described. Basic relations of composite material micro-mechanics have been represented. Specifics of mathematical simulation taking into account assumptions made have been described by example of developed framework of electro-optical system with one-side enforcement by ribs. Results of experimental determination of carbon-filled plastic characteristics used in design of stable-size optical telescope frame structure have been represented; advantages of finite-element method as one of the basic methods for solving the boundary value problem in applied mechanics have been reflected. Reasonableness of analytical approach using in the initial development stage in order to shorten the period of design has been demonstrated. The leading part of finite-element simulation has been determined in behavior prognostication of structures at different operating stages. Stable-size supporting composite frameworks developed taking into account defined sequence of structural design have been showed. Described staging of structure making has been allowed to process and systematize data during design and experimental execution, refine structural model parameters, increase the confidence level and verify it.

Keywords: large-size composite structures, composite structure integrity concept, stable-size supporting structure, optical telescope, parametric analysis of structure, finite-element method, mathematical simulation, staging of stable-size structures.
