The accuracy of hot press forming process simulations with unidirectional fiber reinforced thermoplastics is not at the desired level. Fundamental knowledge about the interactions between adjacent plies is needed to enhance predictive quality. Several mechanisms can be distinguished during hot press forming of composites. This thesis focuses on...

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...

In this comparative eco-design study, the environmental impact of LM’s 58.7 blade was assessed for multiple material composition and waste management scenarios. Material variations were largely focusses on the resin fraction of the blade. This is since the matrix has the biggest impact of all materials and has a big impact on the available waste...

At this moment, industrial robot arms are increasingly used to automate manufacturing processes in the aerospace industry. However, these robot arms lack position accuracy to effectively mill parts or assemble products. In this work, this gap is investigated following two approaches; on one hand existing calibration methods of robot arms are...

Residual stress analysis within hybrid structures is the focus of this study. The non linear stresses through the thickness are determined using a semi-destructive method known as Incremental Hole Drilling (IHD). Finite element modeling is used to build a mathematical code simulating GLARE laminates with initial residual stresses applied. The...

Fibre metal laminates (FML) are manufactured by stacking metal sheets and fibre reinforced prepreg in an alternating fashion, and curing it in an autoclave. The most well-known FML is Glare, which has been successfully applied on Airbus A380 for its fuselage skin. It consists of aluminium sheets and glass fibre prepregs. FMLs have a better...

Clear ice formation on aircraft is a large economic and safety problem. The phenomenon, also known as ‘freezing rain’, usually occurs when subcooled rain droplets impact the aircraft while it descends from high altitude to prepare for landing. It can quickly increase the aerodynamic drag by up to 80% and reduce the lift force by 50%. Inefficient...

Composites have been widely applied in current aerospace structures. In spite of various advantages that composites have, the sensitivity to the impact damage for the composite materials has become a severe threat to the structural integrity of aerospace structures. Therefore, this research work focuses on embedding metal layers in the composite...

In this report, the possibility of replacing high performance thermoplastic polymers with alternative low-cost ones is investigated. Since thermoplastics offer fast processing times and the opportunity to use efficient production processes which are not suitable for thermosets, they are an attractive material<br/>system for the aerospace...

In order to produce more complex parts, additive manufacturing is on the rise as a competitor for more conventional manufacturing methods. Unfortunately, additive manufacturing often produces products with a less desirable tolerance and surface roughness. Subtractive methods require special tooling and fixtures for each part design and typically...

Thermoplastic composites are very attractive for aerospace structures due to their high specific strength and stiffness, enhanced toughness and high temperature resistance. One of the manufacturing methods used to produce thermoplastic composite parts is press forming. Press formed parts typically have constant thickness and fibre orientation....

This thesis is about the structural design of a composite non-pressure hull of a double hull submarine. After performing a background research in which amongst others load cases have been described, a tool has been created for the initial sizing of the pressure hull and non-pressure hull (i.e. outer hull and superstructure). Parts of the tool...
