Reflectivity of carbon fiber
Web2. dec 2024 · Twill-weave carbon fibre reinforced polymer is measured as a reflector material for electromagnetic waves at 60 GHz. The reflectivity at millimetre wavelength … WebCarbon fiber reinforced polymer (CFRP) is measured as reflector material for millimeter waves at 60 GHz. Reflectivity is measured to characterize material anisotropy in a mono-static setup. Disc shaped material samples are rotated in steps of one degree. Four commonly employed CFRP are investigated: unidirectional fibers, plain-weave, twill-weave …
