Abstract

The paper presents an experimental setup, experiments on measuring and calculation of light pressure on structural materials for different angles of incidence of light. This calculation is necessary to determine the materials lighting properties and the total forces moment of solar pressure. As a construction material, industrial metal fiber (net-textile) was used. Net-textile is the material of large-diameter spacecraft antennas. More than 4 000 experimental measurements of the transmittance and reflection coefficients of net-textile were carried out for the calculation.
