Twill-weave carbon fibre reinforced polymer is measured as a reflector material for electromagnetic waves at 60 GHz. The reflectivity at millimetre wavelength shows a predominant direction, which coincides with the diagonal pattern of the twill's top layer. In the remaining directions, the investigated 2/2 twill-weave composite's reflectivity is almost isotropic.
