NOVELTY - The method comprises providing an elongate core, surrounding the elongate core with a cylindrical textile structure (100), arranging the elongate core surrounded by the textile structure in a mold, pressing a part of the textile structure against the mold, injecting a curing agent into the mold to interact with the textile structure for forming the turbine blade, providing a further elongate core, surrounding the further elongate core with a further textile structure, and arranging the further elongate core surrounded by the further textile structure next to the elongate core in the mold.    USE - The method is useful for manufacturing a turbine blade (claimed) such as a rotor blade for wind turbine and/or a water turbine.    ADVANTAGE - The method enables simple, economic and rapid manufacture of the turbine blade with improved stability and physical properties such as thickness and stiffness, high quality and desired shape.    DETAILED DESCRIPTION - The method comprises providing an elongate core, surrounding the elongate core with a cylindrical textile structure (100), arranging the elongate core surrounded by the textile structure in a mold, pressing a part of the textile structure against the mold, injecting a curing agent into the mold to interact with the textile structure for forming the turbine blade, providing a further elongate core, surrounding the further elongate core with a further textile structure, arranging the further elongate core surrounded by the further textile structure next to the elongate core surrounded by the textile structure in the mold, and pressing a part of the further textile structure against the mold. The textile structure: is woven around the elongate core by a three-dimensional weaving process; is formed by wrapping a textile sheet around the elongate core; comprises layers including an inner layer and an outer layer, which surrounds the inner layer; and is integrally formed. Each layer comprises a specific textile material or a spacer material. A composition of material for the layers is varied along a longitudinal axis and/or a circumference of the cylindrical structure. The outer layer is slipped around the inner layer. The inner layer is surrounded by an intermediate layer, which eases slipping of the outer layer around the inner layer. INDEPENDENT CLAIMS are included for:    (1) a system for manufacturing a turbine blade; and    (2) an intermediate member for manufacturing a turbine blade.
