The use of high performance thermoplastic composites (TPCs) in the aviation industry has increased over the last years. TPCs have significant advantages such as superior damage tolerance, excellent chemical resistance and the ability to be welded. To date, mechanical fastening, primarily, and adhesive bonding are the two traditional joining...

The influence of the ultrasonic welding process parameters, namely the force and the vibration amplitude, on the crystallinity degree at the welding interface of CF/PPS (carbon fibre reinforced poly(phenylene) sulphide) joints is investigated. Two different sets of parameters, one representing high force and high vibration amplitude (1000 N,...

Plastic is a material that has greatly improved well being for the masses. However, it also contributes significantly to pollution of the natural environment and depletion of natural resources. So far only a small percentage of plastic is recycled and used for the production of new products. Inferior material quality and the inability to make a...

The additively manufacturing industry is emerging rather quickly and has find its way within numerous fields of expertise. Slowly the building industry is adopting these fabrication methods as well, but there are still a lot of challenges. Especially the bonds within the layered structure are demand more research. Numerous researches have...

This master thesis research investigates the possibility to repair carbon fiber thermoplastic aircraft<br/>structures using induction welding. Carbon fiber is conductive and heats up when placed inside an<br/>alternating magnetic field. A generator, coil, and pressure frame are needed to perform induction<br/>welding. The support plates needed...

CO<sub>2</sub> utilisation is gaining interest as a potential element towards a sustainable economy. CO<sub>2</sub> can be used as feedstock in the synthesis of fuels, chemicals and polymers. This study presents a prospective assessment of carbon capture from a hydrogen unit at a refinery, where the CO<sub>2</sub> is either stored, or partly...

The influence of fiber-matrix adhesion on the linear viscoelastic creep behavior of ‘as received’ and ‘surface modified’ carbon fibers (AR-CF and SM-CF, respectively) reinforced polyphenylene sulfide (PPS) composite materials was investigated. Short-term tensile creep tests were performed on ±45° specimens under six different isothermal...

Micro Air Vehicles (MAVs) are small unmanned aircrafts which have a maximum size limit of 150 mm in any direction. They can be used for surveillance, reconnaissance, targeting, etc. To perform such missions, MAVs are required to hover. Hummingbirds, having excellent flight characteristics (such as hovering, ability to fly in any direction,...

The influence of fiber-matrix adhesion on the linear viscoelastic creep behavior of as received and surface modified carbon fiber (AR-CF and SM-CF, respectively) reinforced polyphenylene sulfide (PPS) composite materials was investigated. Short-term tensile creep tests were performed on ±45° specimens under four different isothermal condition;...

This thesis focuses on Public Private Partnerships (PPPs) for infrastructural projects, in which PPPs entail Design Build Finance Maintain (and Operate), or DBFM(O) contracts. The main differences of such contracts with more traditional contracts is the establishment of a project-specific Special Purpose Company (SPC), the need for external...

De toepassing van geïntegreerde contracten is in opkomst. Ze biedt voordelen, maar de toepassing kent ook nadelen. Voordelen ten opzichte van het traditionele model zijn ondermeer de verhoogde sturing op tijd en geld, maar daar tegenover staat een verminderde sturing op het kwaliteitsaspect. Er is een angstbeeld ontstaan bij voornamelijk kleine...

DBFMO staat voor Design, Build, Finance,Maintain and Operate, oftewel Ontwerp, Bouw, Financiering, Onderhoud en Dienstverlening. Dit is een nieuw soort contractvorm, waarbij eigenlijk alle onderdelen van een gebouw door marktpartij zullen worden afgehandeld. In de huidige situatie is het vaak zo, dat een opdrachtgever een nieuw gebouw wil hebben...

Op basis van uitgevoerde analyse en beantwoording van de onderzoeksvragen zijn de onderzoekers van mening dat een eventuele kustuitbreiding tussen Hoek van Holland en Scheveningen financieel haalbaar is, Voorwaarde is wel dat op het nieuwe land de mogelijkheid wordt geboden voldoende aantallen woningen te realiseren. De residuele waarde van...
