Abstract: Methods for manufacturing a wind turbine blade component using a layup head for automatic or semi-automatic layup of fibre material as ply sections from respective rolls of a plurality of rolls in a blade component mould are described. The methods generally include: defining a list of ply sections for the blade component including the layup sequence and length of each ply section; generating a selection of layup plans using the list, a subset of the plurality of rolls and the initial lengths of fiber material on the rolls; selecting one layup plan in constraint of at least one criterion, such as optimisation of the remaining amount of fibre material waste on the plurality of rolls in a length direction, and controlling the layup head and plurality of rolls to perform the selected layup plan in manufacturing of the blade component in the blade component mould.

Abstract: A method of producing a single assembled longitudinally extending fibre layer for use in a later resin infusion process for manufacturing a fibre-reinforced composite structure is described including steps: a) providing a first fibre mat comprising unidirectional reinforcement fibres oriented in a longitudinal direction of the first fibre mat, b) providing a second fibre mat comprising unidirectional reinforcement fibres oriented in a longitudinal direction of the second fibre mat, c) arranging the first fibre mat and the second fibre mat so that unidirectional fibres of one end of the first fibre mat adjoin one end of the second fibre mat in a single plane at a common boundary, and d) splicing unidirectional fibres of the first fibre mat at one end of the first fibre mat to unidirectional fibres of the second fibre mat at one end of the second fibre mat in order to form a splicing joint.
