Abstract
A method for manufacturing a wind turbine blade, comprising the steps of: arranging (SS) a joining portion () comprising a fibre lay-up inside adjacent blade sections, covering (S) the joining portion () and the adjacent blade sections at least partially with a vacuum bag, and applying vacuum to a space () covered by the vacuum bag (), infusing at least the fibre lay-up () with a resin () and curing (S) the resin () to obtain a cured joining portion () joining the blade sections () inside. A light-weight and at the same time strong blade section joint is provided. In particular, the strength of this laminate joint formed by vacuum infusion is comparable to the strength of the pristine laminate. Compared to a connection using an adhesive, the laminate joint formed by vacuum infusion provides a lighter and stronger blade section joint, in particular, a better weight-to-strength performance.
