Эффективным является применение композиционных конструкционных материалов на основе углепластика, которые позволяют в 1,5–3 раза уменьшить массогабаритные характеристики крупногабаритных оптико-электронных модулей и в 15–20 раз снизить коэффициент линейного температурного расширения в сравнении с металлическими корпусами. Важной характеристикой углепластиков являются их оптические свойства, которые обуславливают взаимодействие композиционного материала с электромагнитным излучением оптического диапазона. Цель настоящей работы заключалась в разработке методики оценки влияния корпуса оптико-электронных модулей из углепластика на светорассеяния в объективе оптико-электронных модулей посредством компьютерного моделирования в пакете прикладных программ Zemax. Рассматривается степень влияния рассеянного, отраженного и поглощенного потока излучения на качество построения изображения. Проведены экспериментальные исследования по определению двулучевой функции отражательной способности гониометрическим методом для образцов-свидетелей из углеродной ткани ЛУП-0,1 эпоксидного связующего ЭДТ-69У с клеевым слоем ЭПОФЛЕКС-0,4 и алюминиевым сотовым заполнителем 5056-3,5-23-A. Рассеянное излучение регистрировалось в пределах пространства полусферы над поверхностью образца-свидетеля. Направление приема оптического излучения задавалось зенитным (0º &lt; θ &lt; 90º) и азимутальным (0º &lt; φ &lt; 180º) углами с шагом 10º. Установлено, что поверхность образца-свидетеля рассеивает излучение в малом диапазоне углов (около 20º) с ярко выраженной направленностью. Выявлено, что углепластики характеризуются интегральным коэффициентом отражения, в 3–4 раза большим по сравнению со специальными покрытиями. </p></abstract><trans-abstract xml:lang="en"><p>Spacecraft optoelectronic modules traditionally have aluminum alloy or titanium alloy casing which substantial weight increases fuel consumption required to put them into orbit and, consequently, total cost of the project. Carbon fiber reinforced polymer based composite constructive materials is an efficient solution that allows reducing weight and dimensions of large optoelectronic modules 1,5–3 times and the coefficient of linear thermal expansion 15–20 times if compared with metals. Optical characteristic is a crucial feature of carbon-fibre-reinforced polymer that determines composite material interaction with electromagnetic emission within the optical range. This work was intended to develop a method to evaluate Carbon fiber reinforced polymer optoelectronic modules casing effect on lens scattering by computer simulation with Zemax application software package. Degrees of scattered, reflected and absorbed radiant flux effect on imaging quality are described here. The work included experimental study in order to determine bidirectional reflectance distribution function by goniometric method for LUP-0.1 carbon fabric check test pieces of EDT-69U epoxy binder with EPOFLEX-0.4 glue layer and 5056-3.5-23-A aluminium honeycomb filler. The scattered emission was registered within a hemisphere above the check test piece surface. Optical detection direction was determined with zenith (0º &lt; θ &lt; 90º) and azimuth (0º &lt; φ &lt; 180º) angles with 10° increment. The check test piece surface was proved to scatter emission within a narrow angle range (approximately 20°) with clear directivity. Carbon fiber reinforced polymers was found to feature integrated reflectance coefficient 3 to 4 times greater than special coatings do. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>углепластик</kwd><kwd>оптико-электронный модуль</kwd><kwd>светорассеяние</kwd><kwd>коэффициент отражения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbon-fibre-reinforced polymer (CFRP)</kwd><kwd>optoelectronic module</kwd><kwd>lens scattering</kwd><kwd>reflectance coefficient</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Конструктивно-технологические решения создания корпусных элементов из композиционных материалов блока оптико-электронного модуля автоматического космического аппарата [Текст] / И.Л.
