Mohabeddine, A.I. (author), Malik, Ghassan (author), Correia, José (author), De Jesus, Abílio (author), Fantuzzi, Nicholas (author), Miguel Castro, José (author)The use of the brittle adhesives commonly adopted in construction industry do not provide the best performance for steel structures. CFRP/Steel joint bonded with extremely tough adhesive achieve much higher strength and ductility. However, tough adhesives are not developed for the construction industry and their cost may question the...journal article 2023

Nijemeisland, M. (author), Meteleva-Fischer, Y. (author), Garcia, Santiago J. (author)The most widely accepted test for bond durability analysis in aerospace metal-bonded structures is the bondline corrosion test introduced in the late 90s. Little progress has been made however on non-destructive testing methods that allow determining the bond quality after years of use. Here, a non-destructive method based on dielectric...journal article 2022

(author), Zhang, Kouchi (author), Leijtens, Johan (author), Sarro, Pasqualina M (author)In this paper we present a sun position sensor platform with a scalable approach for the 3D integration of the sensor optics. This would facilitate the sun position sensor miniaturization, reduces fabrication cost and mitigates the need for sensor calibration. The sun position sensor platform is implemented in a seven mask BICMOS technology with...conference paper 2021

Pascoe, J.A. (author), Zavatta, N. (author), Troiani, E. (author), Alderliesten, R.C. (author)The effect of adhesive thickness on fatigue crack growth in an epoxy film adhesive (FM94) was investigated, using a combination of experiments and numerical modelling. For the range of thicknesses investigated an increased thickness led to an increased crack growth rate. It was found that the energy required per unit of crack growth did not...journal article 2020

Wang, W. (author), Poulis, J.A. (author), Teixeira De Freitas, S. (author), Zarouchas, D. (author)Adhesive bonding is a highly desirable joining technique to join composites to metals. The surfaces of both composite and metal substrates have to be carefully treated before bonding them together, in order to avoid interface failure between the adherend's surface and adhesive. This paper describes the surface pretreatments on carbon fiber...conference paper 2020
