Li, Jiayu (author), Accardo, A. (author), Liu, Shutian (author)Micro/nanoscale additive manufacturing provides a powerful tool for advanced materials and structures with complex and precise features. For instance, the feature resolution of two-photon polymerization (2PP) can reach 200 nm. At this scale, materials properties can change, and the influence of the size effect cannot be ignored. Therefore, it...journal article 2024

Werlen, Vincent (author), Vocke, Richard (author), Brauner, Christian (author), Dransfeld, C.A. (author), Michaud, Véronique (author), Rytka, Christian (author)A new model is proposed for the consolidation of hybrid textiles, in which air entrapment and dissolution are considered. One of the key parameters is tow permeability, which is described by the analytical model of Gebart and validated at very high fibre volume fractions by direct tow permeability measurement. The model also takes into...journal article 2023

Teixidó, Helena (author), Caglar, Baris (author), Michaud, Véronique (author)We seek to address how air entrapment mechanisms during infiltration are influenced by the wetting characteristics of the fluid and the pore network formed by the reinforcement. To this end, we evaluated the behavior of two model fluids with different surface tensions, infiltrating three carbon fiber reinforcements, by means of X-ray...journal article 2023

Christoforidou, A. (author), Verleg, R.L. (author), Pavlovic, M. (author)Resins are essential structural materials predominantly used in load-bearing connections such as adhesively bonded joints and resin-injected bolted connections. In an effort to improve the latter, a new injection material, Steel Reinforced Resin (SRR), has been developed, consisting of spherical steel particles embedded in a resin. SRR's...journal article 2023

Dyer, W.E. (author), Kumru, B. (author)The aerospace industry has been benefiting from the utilization of polymer materials since fiber-reinforced polymer composites (FRPC) offer high performances at low densities compared to metals. FRPC facilitated the design of lightweight materials, which is extensively used in aviation today. Since their first integration into structural...review 2023

Teixidó, Helena (author), Broggi, G.C. (author), Caglar, Baris (author), Michaud, Véronique (author)We propose a methodology to monitor the progressive saturation of a non-translucent unidirectional carbon fabric stack through its thickness by means of X-ray radiography and extract the dynamic saturation curves using image analysis. Four constant flow rate injections with increasing flow speed were carried out. These were simulated by a...journal article 2023

Olivier, G. (author), Csillag, Fruzsina (author), Christoforidou, A. (author), Tromp, Liesbeth (author), Veltkamp, Martijn (author), Pavlovic, M. (author)Due to the low weight and excellent durability of composite materials, Fibre Reinforced Polymer (FRP) decks mounted on steel superstructures are becoming increasingly common in engineering practice. Bolted joints are generally used to facilitate connections between an FRP deck and steel girders in road bridges. The connections are subjected...journal article 2023

SHETTY, SOWRABH (author)In the past two decades, there has been a substantial increase in the use of natural fibres in bio-composites; these fibres have a Greenhouse gas (GHG) footprint of about 60,000 times less than virgin carbon fibres. The synthesis of polymers from renewable resources is gaining importance as a solution to the critical issues of depleting crude...master thesis 2022

Blommert, Yannick (author)Laser-assisted automated fiber placement (LAFP) is a promising additive manufacturing technique for the production of large aerospace components. Thermoplastic prepreg tapes will be placed ply-by-ply on top of a mould and in-situ consolidated. This is beneficial for higher production rates. The mechanical performance of thermoplastic composite...master thesis 2022

Pijnenburg, Kees (author)Improved handling methods are required in order to decrease the manufacturing cost of solar cells and flat panel display. A potential method would be to use a contactless handling system based on air bearing technology. As the name implies, the substrate levitates on a thin film (~10 μm) of air. The viscous shear force is used to exert a lateral...master thesis 2022

Langejans, G.H.J. (author), Aleo, A. (author), Fajardo, Sebastian (author), Kozowyk, P.R.B. (author)An adhesive is any substance that bonds different materials together. This broad definition includes materials used in everything from hafted stone tools to monumental architecture. In addition, the combination of bonding, plasticity, and insolubility meant that some adhesives were exploited for waterproofing and sealing of materials, as self...journal article 2022
