摘要:
A method of producing a composite shell structure in the form of a wind turbine blade shell part having a reinforced fiber material embedded in a cured resin includes: providing a mold part having a contour defining the outer surface of the composite shell structure; providing a preform forming part shaped complementary to the mold part molding surface; forming a preform of dry fiber material on the surface of the preform forming part; arranging the mold part and the preform forming part in an assembled position with the mold part molding surface facing the preform forming surface; releasing the preform from the preform forming surface so that it is received on the mold part molding surface; removing the preform forming part from the mold part; forming a mold cavity by means of a second mold part arranged on the preform; providing resin in the mold cavity; and curing the resin.

A transportation and storage system for a wind turbine rotor blade comprises a tip end frame assembly comprising a tip end receptacle and a tip end frame. The tip end receptacle comprises an upwardly open tip end-receiving space for receiving a portion of the tip end of the blade and having a supporting surface for supporting the blade, a lower surface allowing the tip end receptacle to rest upright on a substantially horizontal surface, such as the ground, and releasable retaining means for releasably retaining the tip end of the blade in the receiving space of the tip end receptacle. The tip end frame comprises an upwardly open receptacle-receiving space for receiving the receptacle and provided with positioning means for positioning the receptacle in the tip end frame. A base part defines a bottom surface allowing the tip end frame to rest upright on the ground.

A method of producing a composite structure comprising fibre reinforced material and having a longitudinal direction is described. The method comprises the following steps: a) manufacturing a first structure comprising a first cured composite part having a first thickness and a longitudinal direction with a first end, and a number of first fibre layers extending from the first end, b) manufacturing a second structure comprising a second cured composite part having a second thickness and a longitudinal direction with a second end, and a number of second fibre layers extending from the second end, and c) arranging the first structure and the second structure so that the first end faces towards the second end, and arranging the first fibre layers and the second fibre layers so that at least a part of the first fibre layers overlap at least a part of the second fibre layers in the longitudinal direction, d) supplying liquid resin in order to impregnate the first fibre layers and the second fibre layers, and e) curing the liquid resin in order to form the composite structure comprising the first cured composite part, the second cured composite part, and an intermediate composite part including the first fibre layers and the second fibre layers.

The present invention relates to methods for producing low fat spread emulsions stabilised with dairy proteins. The water phase is stabilised by heat denatured whey proteins at low calcium concentrations. After heat treatment pH of the water phase is adjusted to neutral or acid conditions. The present invention also relates to methods for producing a whey protein product that can be used as a stabilising food ingredient.
