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.

Abstract: A method of manufacturing a wind turbine blade component in form of a shear web is described. The method comprising the steps of: a) providing a pre-manufactured shear web body having a first side and a second side as well as a first end and a second end; b) providing a first pre-formed web foot flange comprising a fibre-reinforcement material; c) arranging a first fibre layer from the first pre-formed web foot flange and to a part of the first side of the shear web body; d) arranging a second fibre layer from the first pre-formed web foot flange and to a part of the second side of the shear web body; e) supplying a resin to said first fibre layer and second fibre layer simultaneous with or subsequent to steps c) and d); and f) allowing the resin to cure so as to form the shear web.
