Dating back to 10,000 B.C.E., fermentation has served as a vital tool primarily for food preservation. In the nineteenth century, Louis Pasteur put forth the proposition that the occurrence of fermentation is predominantly facilitated by the presence of microorganisms. Pasteur’s discovery spurred comprehensive studies on microorganisms,...

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...

Purpose - With the ongoing rise of product returns in the fashion industry, exacerbating its GHG footprint when it should be lowered, this paper aims to provide a measurement tool for companies to improve the environmental impact of product returns while considering the economic costs. Companies do not have an understanding of the impact of...

Mycelium based composites (MBC) have revolutionised the field of material production, where a living fungus is employed to overgrow and bind lignocellulosic substrate materials together. Their bio-based nature, low embodied energy, and biodegradability, mark their great potential to reduce the increasing pressure conventional materials put on...

A building block pyramid is designed used to evaluate a composite aircraft structure, combining tests and analyses, using stiffened panels, single-stringer specimens and coupons. Failure in these structures can be caused by postbuckling-induced skin-stringer separation, which is complex, involving matrix cracks, fibre bridges, and delamination...

In composite structures, delamination damage is typically the most common failure mechanism. Accurately characterizing the delamination behaviour of composite laminates is therefore crucial for predicting the fatigue safe-life of such structures. To this end, double-cantilever beam (DCB) composite specimens are used to measure the interlaminar...

In Amsterdam, more than 30 steel-concrete composite bridges were constructed from 1880-1960 without mechanical connectors and transverse reinforcement. Currently, there are no simplified analytical methods to determine the bearing capacity of these bridges. Thus, the bearing capacity is verified using NLFEM or oversimplified analytical...

An organ-on-chip (OoC) is a microelectromechanical (MEMS) device that aims to recapitulate in-vitro the physiology of the smallest functional unit of an organ in order to perform drug analysis or study disease models. OoCs are very complex systems that require actuation and sensing capabilities within controlled and delicate environment. The...

This research, structured in a six-phase iterative framework, decodes the rationale behind complex façade geometries & their dependence on conventional materials. Parallel with rising climate consciousness, the built environment is searching for mechanically competent, lower-impact material alternatives in the façade sector compatible with...

In contemporary architecture free-form buildings play an important role. The materials used, for example fibre reinforced composites or concrete, are not sustainable. Because the built environment is responsible for a significant part of the global resource usage and because it is one of the most polluting industries it is important to make...

The Province of South-Holland is one of the fastest-growing regions of the Netherlands. The metropolitan provides employment opportunities, has an (inter) national mobility network, and houses densely urbanised landscapes. Because of these benefits, the population keeps increasing. This reflects the need for an addition of 200.000 dwellings in...

According to the Oxford Learner’s Dictionaries, the notion of “space” can be read in several ways, of what is the five general understandings of it would be: outside earth’s atmosphere, empty area, period, freedom, and lastly, where things exist/move. With the speed, amount of information, and technology we are currently facing in the 21st...

A structural supercapacitor (SSC) is a composite material that bears mechanical loads and stores energy, and its encapsulation method of the device is vital for scale-up. Here we present an SSC with an encapsulation interface consisting of spread-tow fabric electrodes and glass fabric encapsulators infused with epoxy resin. Through surface...

Delamination is a significant failure mode that has been the subject of extensive research in laminated structures. The interface in assembly structures often represents the susceptibly weak link and necessitates careful consideration to guarantee structural stability. It is of utmost significance to understand the behaviour of the delamination...

Laser-assisted fiber placement (LAFP) is an automated manufacturing technique with promising potential to produce larger aerospace structural components using thermoplastic composites. However, during the rapid heating phase, deconsolidation of composite tapes can occur, resulting in negative effects on bond forming ability. This study aimed to...

Thermoplastic composites enable new manufacturing techniques such as conduction welding to make the aviation industry more sustainable, while at the same time, provide great benefits to cost-efficient high-volume production. One of the benefits of welding is that it reduces the amount of mechanical fasteners required. Fastener-free joining also...

Frontal polymerization (FP) has emerged as a promising alternative to traditional bulk curing methods in recent years for manufacturing high-performance fibre-reinforced polymer (FRP) composites. The energy utilized in this self-propagating curing strategy is solely derived from the exothermic enthalpy of polymerization, making it potentially...

The goal of this thesis project was to explore how material originating from thermoplastic composite wind turbine blades (TPC WTB) can be reshaped. The insights gained during exploratory activities were used to design a re-use application. The demonstrator model should inspire people to develop other applications and build upon the foundations...

Fiber reinforced composites have been increasingly used in the aerospace and automotive industry, due to their potential advantages for designing flexible, strong and lightweight structures. More recently they are also being considered for the manufacturing of marine propellers. Since they have the potential to lower the weight, lower the...

Until recently, tenders in Europe were awarded to wind farm developers based on the highest auction prices or the lowest subsidized bids. The wind industry has suggested that non-price-related criteria should be considered for tenders, like plans to reduce greenhouse gas emissions. As a result of the sustainable tender criteria, greenhouse gas...
