Abstract

1,260,484. Moulding propeller blades. DOWTY ROTOL Ltd. 22 April, 1969 [6 May, 1968], No. 21397/68. Heading B5A. [Also in Divisions B7 and F1] A method of making a blade for a compressor, fan, propeller or the like comprises the steps of laying-up at least one layer of epoxy resin impregnated woven glass cloth 15 which is looped around a pin like element 14, laying over the cloth 15 layers of epoxy resin impregnated unwoven carbon fibres 16 to define the blade working portion, and curing the assembly in a mould. After curing the blade is sandblasted and dipped in a bath of polyurethane to provide an abrasion resistant coating. The element 14 may be a pin of metal or reinforced resin. During the laying-up process prior to curing, a sheath of stainless steel may be embedded in the carbon fibres 16 to form the blade leading edge. The fibres 16 are laid so that some extend longitudinally of the blade and are overlapped by other inclined fibres. The layers of woven glass cloth 15 are also laid so that their main fibres are similarly arranged.
