Статья посвящена прогнозированию теплозащитных и механических свойств композиционных материалов на основе пористых заполнителей. Приведены аналитические зависимости определения коэффициента теплопроводности материалов гомогенной и гетерогенной структуры. На основе метода конечных элементов разработана методика численного определения коэффициента теплопроводности композиционных материалов вариатропного строения. Результаты компьютерных исследований сопоставлены с зависимостями, полученными на аналитических моделях. Показана целесообразность использования многослойных композиционных материалов на основе пористых заполнителей в несущих и ограждающих конструкциях оболочечного и пластинчатого типов.
