The layup process of large composite structures made from dry reinforcement fabrics is considered. One such structure is a wind turbine blade, for which the current draping process is mostly manual. Automating the draping process will, therefore, low

The notion of the achievement society and the achievement generation has, in recent years, become an influential way of explaining the increase in mental health and psychosomatic complaints among Scandinavian youth. However, the theories produced abo

Previous research has linked demographic shifts in mental health issues among adolescents to a rise in personal expectations and a strong performance imperative, particularly within the educational system. This study aims to understand how early adol

This paper concerns shear testing of a quasi-unidirectional non-crimp fabric used for wind turbine blades. In this context “quasi” refers to the fact that the majority of the reinforcement is oriented along the longitudinal direction with a small

The draping of glass fiber fabric in a wind turbine blade mold is analyzed and optimized. Unlike for smaller composite parts, the size of the blade mold section necessitates multiple courses, i.e. roll-widths of fabric. The overarching goal is thus t
