More and more wind turbines are erecting in the landscape, stemming from the need for sustainable energy. However, less attention is paid to the secondary effects of these wind turbines, more specifically, the wind turbine blades. Wind turbine blades are made of composite material, a material that provides many advantageous properties for the...

With dramatic increase in 3D printing applications in industry, sandwich panels with 3D printed cores have gained a lot of attention recently. In harmony with global movement towards sustainability and low-carbon emission industries, sandwich panels with easy-to-repair and cost-effective cores would be very attractive structures. In this...

From the beginning of the 21st century, thin glass has been used as a screen protector for electronic devices and smartphones. During the last 10 years, several studies have been carried out to introduce the thin glass in the building industry. The advantages of this material are light weight, high strength and high flexibility. On the other...

EX-CORE, a novel foam core material developed by Donkervoort Automobielen B.V., allows the creation of complexly shaped sandwich structures in a one-shot out-of-autoclave manufacturing process. Products with small tolerances and high surface quality on all surfaces can be obtained. The EX-CORE technology has achieved its intended goal at...

Future wind turbines require larger rotor blade radius, leading to an increase of rotor swept area. The larger rotor swept area results in more energy production of the wind turbine. Further increase is however limited as a result of the structural weight, which induces a large bending moment and could result in buckling of the rotor blade. An...

This paper describes the engineering steps taken in order to investigate the potential of glass sandwich elements, made of 2 glass skins separated by a glass core in the form of spacers, as a way to create planar elements with a high stiffness to weight ratio, reducing material consumption in structural glazing applications. The aim is to...

Full-scale fatigue tests were performed on two retrofitted orthotropic bridge decks (OBDs). The retrofitting systems consist of adding a second steel plate on the top of the existing deck. The aim is to reduce the stresses at the fatigue-sensitive details and therefore extend the fatigue life of the OBD by stiffening the existing deck plate....

X-core is a novel foam core material developed by Donkervoort Automobielen, it enables a unique one-shot process for seamless composite sandwich structures with mould-defined features all-around. The foam is co-cured to carbon fibre/epoxy prepregs, in this form the process is currently used to make car components for the Donkervoort D8 GTO RS....

Transparency is embraced more and more in contemporary architecture and therefore glass has become one of the most important materials in the building industry. In structural glass applications the elements are dimensioned based on stiffness and strength requirements. This research investigates the potential of glass sandwich structures as a way...

A new linear sandwich shell element is presented, based on the third order shear deformation theory from Reddy in combination with a `zig-zag' model. Following from a set of benchmark tests, the sandwich element shows superior accuracy in determining facesheet stresses compared to the Abaqus S4 shell element and a good correlation with 3D finite...

Subject of this thesis is the development of a lightweight, low-cost and eco-friendly composite structural module, out of a self reinforced Polypropylene (srPP) skin and a core of Polyethylene Terephthalate (PET) bottles. The module can be easily mass-produced, transported, assembled and disassembled, and able to be fully recycled after the end...

An experimental investigation was performed to examine the effect of low energy impact damage on tension-compression fatigue properties of sandwich panels. The specimens consisted of a 9 mm thick Nomex honeycomb and face sheets of (0,± 45) and (± 45,0) Carbon/epoxy. Drop weight impact was applied to create internal laminate damage. In order to...

Flight simulation fatigue crack propagation tests on 202U-T3 and 7475-T761 aluminum alloy sheet were carried out using a gust spectrum representative of the load history of an under wing skin in a transport aircraft. The investigation included tests at several design stress levels and in environments of laboratory air and air plus water spray....
