Luque Martin-Sacristan, Araceli (author)Paralympic sports are growing more popular. Besides the dedicated training of the athlete, technology is crucial to empower amputees to perform at their highest level. The recent carbon fibre Running-Specific- Prosthesis (RSP) have energy stored and return capabilities that allow runners with amputations to perform almost as able-bodied. However...master thesis 2021

Smit, Daan (author)The aim of this study is the assessment of the mechanical performance reduction due to manufacturing-induced gaps and voids (delaminations) in thermoplastic composite pipes. The effects of gaps are assessed based on the finite element modeling of an internal pressure load case and is validated by experimental tensile coupon testing. Results show...master thesis 2020

van Zanten, Floris-Jan (author)An approach to optimizing variable stiffness laminates for strength is modified to allow for the optimization of curved structures. A density function to take in account the effect of gaps and overlaps during optimization created by fibre steering is found with the functional approximation method. The density plot of a plate for 2 standard cases...master thesis 2018

Zuurendonk, Bas (author)This report shows the intended process to automatically manufacture Carbon Fibre Reinforced Thermo Plastic (CFRTP) double bend frames. Bicycle rims were chosen as a scaled down representation for difficult to manufacture double bend products. Fuselage frames require a too large facility. The aim is to manufacture CFRTP products in an automated...master thesis 2018

van der Sandt, Sebastiaan (author)The subject of this thesis is the forming of sandwich panels on a reconfigurable mould. The field of research is composite sheet forming. This novel manufacturing process at Curve Works has problems with panel quality, especially out-of-plane wrinkles. Exploratory research on quality improvement is performed by analysing the underlying...master thesis 2018

van Koppenhagen, Guido (author)A proposed future mode of mass transit is the hyperloop system, in which magnetically levitating passenger pods travel at high speed through a tube held at low pressure. This thesis will investigate the dynamics of such a system, and determine the influence of various parameters on the dynamic response of the system. The tube has been modelled...master thesis 2018

van den Bergen, Damy (author)The dutch government plans to build a vast amount of offshore wind turbines. Therefore, it will be necessary to decrease the costs of the transportation, installation and maintenance of these wind turbines. Jules Dock tries to achieve this by replacing the steel design of the next generation 10MW wind turbine tower by a flexible composite design...master thesis 2017

Verheijen, Bob (author)Spacecraft are under constant threat of structural damage from hypervelocity impacts by micrometeoroids and orbital debris. To bolster the shielding used for protection against these impacts, ballistic materials can be employed. Aramid-based materials are currently used aboard the International Space Station (ISS), but Ultra High Molecular...master thesis 2017

Broekens, M.R. (author)In this thesis, the relation between the manufacturing parameters and the mechanical properties of Fused Filament Fabrication (FFF) materials is analyzed to gain a better understanding of interaction between these two. The existing literature was first analyzed to get an understanding for the process, resulting in a proposed mesostructural and...master thesis 2017

Callens, S.J.P. (author)The concept of twin matrix composites was proposed in the 1980s by Vasiliev and Salov1, as a means to increase the transverse tensile failure strain of unidirectional composites without sacrificing the longitudinal tensile strength. This could be achieved by impregnating glass fiber bundles with a stiff epoxy matrix, and embedding the cured...master thesis 2017

van den Berg, L.J. (author)A FEM-based tool was developed for optimization of the geometry of an adhesive joint for implementation in a composite micro truss structure. A genetic algorithm was employed to optimize the adhesive fillet and adherend local end geometry towards a uniform state of strain in the adhesive layer. It was found that the peak maximum principal strain...master thesis 2016
