Abstract

It was theoretically shown by the authors in a previous article that by adding a layer of metal on the outside of a carbon fiber-reinforced composite shaft, the bending natural frequencies of the shaft could be increased in some cases due to reduction of the effects of shear deformation by the metal layer. In the present study, composite shafts having a metal casing have been manufactured by spray deposition process over filament wound, fiber reinforced polymeric shafts. The natural frequencies of the spray deposited composite shafts have been measured and found to compare well to theoretically calculated values. The experiments also confirm the shear deformation effect described above. Some manufacturing issues on the spray deposition of metals over carbon fiber-reinforced plastics are addressed.
