Adhesives have been shown to be an excellent solution for joining fibre reinforced polymer (FRP) components thanks to their capacity to redistribute loads, reduces stress concentrations and contribute to overall weight ...
The use of the stiffened panels in the aircraft/aeronautical industry has been growing in the last decades. On the other hand, the exponential growth in the use of composite materials in the last years has had a ...
Currently, the use of Automated Fiber Placement technology allows, large composite aircraft components to be manufactured with high quality materials and introduce new laminate concepts. Among such concepts are the tow-steered ...
ENG- The primary objective of this thesis was to experimentally determine the elastic in-plane mechanical properties and interlaminar fracture toughness in modes I and II of Markforged® continuous Carbon Fiber reinforced ...
The main objective of work has been to study the bond strength and bond-slip response of NSM CFRP strips in concrete when subjected to sustained loading under different environmental conditions. To this end, two experimental ...
The rehabilitation of civil structures has been gaining importance during the last decades. Owing to their mechanical, corrosion resistance and lightweight properties, Carbon Fibre-Reinforced Polymers (CFRP) present an ...
In recent years, additive manufacturing technologies (3D printing) have been introduced in different fields, such as locomotion and bioengineering, among others. Extrusion by Fused Deposition Modeling (FDM) or Fused ...
Cohesive zone models are widely used for modelling delamination and bonded joints under different loading conditions. In the current thesis, an objective inverse method has been developed to extract the cohesive law from ...
This thesis investigates the fatigue behaviour of fibre-reinforced composite laminates. Fatigue of composite materials is a complex subject both from an experimental and numerical modelling point of view. In this context, ...
El desarrollo de la sostenibilidad en la edificación ha realizado un gran avance en los últimos diez años, mejoras en la eficiencia energética de los edificios con la incorporación del certificado de eficiencia energética ...
The main motivation of this work was to analyse the feasibility of the current stent’s manufacturing process to produce the new bioresorbable stents (BRS) as well as study new manufacturing methods. Fibre Laser Cutting ...
Polymeric materials, which are suitable for high performance applications for example human implants are one of the most expensive available polymers. Standard injection micromoulding process, dedicated for mass production, ...
Triple negative breast cancer (TNBC) accounts for 15-20% of the breast cancers and displays an aggressive profile, poor prognosis, high relapse risk and does not have a targeted therapy. In the last years, breast cancer ...
Advanced joining technologies such as bonded joints play an important role to develop more efficient and durable structures. The present Thesis gives a step forward and proposes different solutions to characterise the ...
In recent decades, several meso-scale computational models have been developed for predicting the failure evolution and strength of composite materials. Nevertheless, the complex failure mechanisms of composites pose a ...
Fiber reinforced composite materials are nowadays used in several industrial applications that pursue structural weight reduction to reduce fuel consumption. The stiffness-to-weight and strength-to-weight ratios of composite ...
The overall purpose of this Ph.D. thesis is to contribute to the reliable design of composite structures subjected to fatigue-driven delamination. The aim is motivated by a wish to reduce the amount of experimental testing ...
In recent years, the use of composite materials in the aeronautic, automotive, marine construction, etc. has increased significantly. Hence, there is an increasing need for repair technologies on primary structural components, ...
There is a general trend towards rehabilitation and strengthening of existing reinforced concrete (RC) structures due to the costs associated with the replacement of the structural members and the environmental impact ...
NSM strengthening technique under the influence of temperature and relative humidity, in which the interaction between materials involved is analyzed, is studied in this PhD. Therefore, this work is aimed at contributing ...
