Abstract
The present invention provides a method for constructing from fiber-composite material complex structures having two or more transversely disposed members. By way of example, a composite turbine blade 10 having an aerofoil 12 and an integrally formed footing 14 can be constructed using this new method, which method comprises the steps of forming from fiber-composite monotape a blank 40 in the general shape of aerofoil 12 with the fibers 18' of the monotape being oriented in a generally spanwise direction, exposing the fibers 18' at the root 42 of the aerofoil blank 40, inserting transversely between the exposed fibers 18' a plurality of foot-forming monotapes 17 to form a transversely meshed, tape and fiber structure 68, filling the voids in the transversely meshed structure with powdered matrix material and hot-pressing the filled-in structure 70 substantially according to the desired final shape of the fiber-composite turbine blade.
