Abstract

Fibre reinforced plastics are a commonly used material for primary and secondary spacecraft structures. Besides their excellent mechanical properties, they offer a high potential for thermal applications. At the moment this combined potential of thermal and mechanical material properties is usually limited to the design and simulation of secondary composite’s structures. If both potentials would be combined on full spacecraft level, too, further mass and savings are possible. Hence, it is sought to connect the thermal and structural design in a combined semi-analytical mechanical and thermal 2D/3D FE simulation technique. As a prerequisite this paper focuses on the investigation of an exemplarily load-bearing bonded single-lap joint coupon of two CFRP laminates. The temperature distribution in the coupon is calculated analytically, numerically and subsequently measured in a corresponding thermal vacuum test. It is discussed what are the differences in the analytical and numerical solution and what is required before correlating the results.
