Method of producing a composite structure via intermediate products, the related apparatus and a composite structure obtainable by the method

Abstract

A method of producing a composite structure comprising fiber 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 fiber 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 fiber 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 fiber layers and the second fiber layers so that at least a part of the first fiber layers overlap at least a part of the second fiber layers in the longitudinal direction, d) supplying liquid resin in order to impregnate the first fiber layers and the second fiber 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 fiber layers and the second fiber layers.
