发明名称 A FIBRE PREFORM FOR LAYING ON A CURVED SURFACE OF A MOULD
摘要 A method for making a root section (7) of a wind turbine blade (5), the method comprising: providing a fibre preform (14) comprising the steps of: providing at least one first ply of dry reinforcing material (15); placing a stiffening strip (25) on the at least one first ply of dry reinforcing material; placing at least one second ply of dry reinforcing material on the stiffening strip to form a stack; and binding the stack together along binding rows (16); the method further comprising placing the fibre preform on a curved mould surface such that the binding rows and the stiffening strip are orientated in a chordwise direction; wherein the stiffening strip has a stiffness such that the stack is self-supporting so that the stack does not buckle when laid on the curved mould surface.
