Heezen, Emile (author)Laser satellite communication offers new opportunities in global data transfer, and can provide crucial infrastructure to facilitate the ever-growing demand. Creating an optical link of 10.000 km in length requires a telescope with extreme thermal stability, in an environment where thermal loading is periodical as a result of the satellite’s...master thesis 2022

Qiao, Danyu (author)In recent decades, fibre-reinforced polymer composite structures have seen increased aerospace applications. A typical composite structural element widely used in primary load-bearing aircraft components is the T-joint, which is formed when two orthogonal laminates are joined in a T-shaped arrangement to enable out-of-plane load transfer. Under...master thesis 2022

Pronk, Simon (author)Wind turbines are decommissioned when they reach their endoflife. The reason for reaching endoflife varies per wind turbine, but they all have in common that the wind turbine blades can not be recycled and thus end up as waste. Since a growing amount of wind turbines will reach their endoflife the coming decade, the waste problem will increase....master thesis 2022

Pan, Tanbo (author), Zheng, Yonglai (author), Zhou, Yujue (author), Liu, Yongcheng (author), Yu, Kunlong (author), Zhou, Y. (author)This paper presents the results of an experimental study on the flexural behavior of carbon fibre reinforced polymer (CFRP) anchorage system strengthened reinforced concrete (RC) beams under the coupled effects of corrosion damage and sustained loading. The test beams were subjected to combined accelerated corrosion in 5% NaCl solution and...journal article 2022

Ogugua, C.J. (author), Sinke, J. (author), Dransfeld, C.A. (author)This work quantifies and compares the environmental impact of a thermoset CFRP aircraft skin panel to that of a thermoplastic CFRP panel. This comparison is done using a cradle to gate life cycle assessment including impacts from raw material extraction, manufacturing and end of life. In addition, a hotspot analysis was performed to identify...conference paper 2022

Yue, N. (author), Broer, Agnes A.R. (author), Briand, William (author), Rébillat, Marc (author), Loutas, Theodoros (author), Zarouchas, D. (author)The application of structural health monitoring (SHM) in composite airframe structural elements under long-term realistic fatigue loading needs to consider the structural behavior on the global level, which is an intricate task. The overall structural stiffness is a key design parameter for composite structures and the stiffness degradation...journal article 2022

Hou, Naidan (author), Zhao, Renxi (author), Li, Jian (author), Wang, Xuan (author), Li, X. (author), Cui, Hao (author), Li, Yulong (author)Rain erosion may cause substantial damage to aircrafts during supersonic flight. Such event is investigated here via high-speed waterjet impact on composite laminates. An experimental setup is developed to produce waterjets with the speed up to 700m/s and a finite element model of the waterjet-composite impact event is established. The...journal article 2022

Oranje, Jesper (author)Carbon fibre reinforced polymer (CFRP) composites are well-known for their specific strength and stiffness properties. For the past two decades, various industries have increasingly used these materials to improve performance and reduce emissions. This increased use has caused a problematic growth in both production and end-of-life CFRP waste....master thesis 2021

Tsiangou, E. (author)Welding is a promising alternative to mechanical fastening, as currently used, to join dissimilar (i.e., thermoset- to thermoplastic-based) composite parts in modern aircraft. Thermoset composites can be indirectly welded through a thermoplastic coupling layer co-cured on the surface of the laminate that needs to be welded. One of the main...doctoral thesis 2021

Anand, C. (author), Groves, R.M. (author), Benedictus, R. (author)There has been an increase in the use of ultrasonic arrays for the detection of defects in composite structures used in the aerospace industry. The response of a defect embedded in such a medium is influenced by the inherent anisotropy of the bounding medium and the layering of the bounding medium and hence poses challenges for the...journal article 2021

Ekhtiyari, Amin (author), Alderliesten, R.C. (author), Shokrieh, Mahmood M. (author)This work aims at studying the loading rate dependency of mode I delamination growth in CFRPs, using typical fracture toughness analysis through both the R-curve and the crack tip opening rate. The average SERR is a method of data reduction based on energy balance which has been previously introduced to characterize delamination growth under...journal article 2021

Verhage, Jacco (author)The innovative shear strengthening method using externally bonded CFRP reinforcement to strengthen prestressed concrete I-girders has been investigated in this thesis. These girders potentially have insufficient shear capacity because of the combination of thin webs and insufficient shear reinforcement. Shear failure of these girders should be...master thesis 2020

Kupski, J.A. (author)Adhesive bonding is one of the most suitable joining technologies in terms of weight and mechanical performance for current carbon fiber reinforced polymer aircraft fuselage structures. However, traditional joint topologies such as single overlap joints induce high peel stresses, resulting in sudden failure and low joint strength when compared...doctoral thesis 2020

van Diën, Casper (author)This research experimentally investigates the effects of an impact event during fatigue loading of a CFRP structure. Open-hole specimens were impacted in-situ during a short interruption of a tension-tension cyclic loading program. The impact was aimed directly below the central hole, with the critical fatigue damage path being left and right of...master thesis 2020
