Jongbloed, B.C.P. (author)One of the most promising welding techniques for thermoplastic composites is ultrasonic welding. It is mainly known as a spot welding technique. The relatively new technology continuous ultrasonic welding of thermoplastic composites makes it possible to obtain large fully welded seams with higher load carrying capabilities. However, at the start...doctoral thesis 2022

Tsiangou, E. (author)Welding is a promising alternative to mechanical fastening, as currently used, to join dissimilar (i.e., thermoset- to thermoplastic-based) composite parts in modern aircraft. Thermoset composites can be indirectly welded through a thermoplastic coupling layer co-cured on the surface of the laminate that needs to be welded. One of the main...doctoral thesis 2021

Carnevale, P. (author)A strong pressure towards efficiency improvements in the aviation sector is given by stringent environmental reduction goals and by the growing and volatile fuel prices. Such pressure is even stronger considering the steady growth of air traffic forecasted for the next 20 years. Structural mass reduction is one of the ways to achieve such...doctoral thesis 2014

Teuwen, J.J.E. (author)In previous research, the potential of glass fibre reinforced anionic polyamide-6 (APA-6) composites for use in wind turbine blades was proven. Based on polymer properties, viscosity, processing time, costs and recyclability, APA-6 composites are considered the most suitable reactive thermoplastic material candidate. However, more research is...doctoral thesis 2011

van Rijswijk, K. (author)Due to the increasing costs of fossil fuels and the improved efficiency of wind turbines in the last decade, wind energy has become increasingly cost-efficient and is well on its way of becoming a mainstream source of energy. To maintain a continuous reduction in costs it is necessary to increase the size of the turbines. For the blades a...doctoral thesis 2007
