Abstract: Mathematical multi-level model for calculation of thermo-elastic properties of textile composites on alumochromephosphate binder under high temperature is developed. The model takes in to account a physical-chemical conversations processes in alumochromephosphate binder and glass fibers under high temperature. Comparison of calculation results with experimental data is conducted, it’s shown, that model developed allows to predict a complicated nonlinear character of elastic properties of composite changing under heating up to 1600 Ê. The developed model can be applied for prediction of elastic properties of alumochromåphosphate matrix composites under complicated regime of heating.

Keywords: composite materials, alumochromåphosphate matrix, thermomechanics, thermoelasticity, thermostrength, high temperatures, multi-scale modeling, homogenization method, finite element method.
