Space structures, in particular uninsulated box beam or tubular truss elements, are potentially exposed to a diurnal temperature swing of 200 Cel or higher at the surface of the epxosed truss member. Opposite sides of the same strut element might even develop that temperature differential within the part itself. This paper reports the experimentally determined loss factor and loss modulus on different composites as a function of different resonant frequencies for the first four modes of a fixed-free resonating cantilever beam as a function of temperature from -50 Cel and +2000 Cel.
