23-05: FRP-Carbon Twin Shaft for Axial Fan Blades and Validation on Cofimco’s 38FT Test Rig Treatment Evaluation

23-05: FRP-Carbon Twin Shaft for Axial Fan Blades and Validation on Cofimco’s 38FT Test Rig Treatment EvaluationCofimco extensive research and laboratory tests pointed out in the development of an innovative shaft to connect the blade airfoils to the hub on large axial fans used on cooling towers and air cooled condensers: the pultruded FRP Carbon twin shaft. This type of connection gives to the blade very high strength by optimizing the material distribution in a peculiar shape and maintaining all the advantages of pultruded FRP Carbon material as the
