Article
Epoxies are widely used as adhesives and matrix material for composites in civil infrastructure. As such structures are likely to be exposed to a wide variety of environmental conditions over long service lives, knowledge of their time–temperature sensitivity is desirable. The present study proposes a model describing the evolution of storage modul...
Thesis
The goal of this thesis is thus to clarify the effects of temperature and strain rate on the strength, stiffness and fatigue performance of composite materials as used in the wind energy sector. It thus focuses on glass fibre reinforced composites, which is the mainstream material for wind turbine blades. The temperatures considered are limited to...
Article
Predicting the fatigue performance of composites has proven to be a challenge both conceptually, due to the inherent complexity of the phenomenon, and practically, because of the resource-intensive process of fatigue testing. Moreover, mechanical behaviour of polymer matrix composites exhibits a complicated temperature dependence, making the predic...
Article
Effects of cold climate exposure on structures made of composite materials are scarcely documented. As a result, even if exceptional wind conditions prevail in some cold regions, uncertainties related to composite materials durability at low temperatures may hinder development of wind energy projects in those regions. Therefore, as part of the Wind...
Conference Paper
As wind turbines are likely to be installed in a wide variety of environments, knowledge of their materials mechanical properties under extreme environments is needed. The project presented herein aims at evaluating the effects of temperatures of -40 °C, 23 °C, and 60 °C on the static properties and fatigue lives of unidirectional glass-epoxy compo...
Conference Paper
Full-text available
The wind resources of northern regions are amongst the best the planet can offer. Unfortunately the effects of extreme climatic conditions on properties of composite materials used for wind turbine blades, especially fatigue performances, are not completely understood. In northern climates, these composites would be subjected to thermal loads, agin...
Conference Paper
The durability of composite materials used for wind turbines blades exposed to a northern climate presents uncertainties as their behavior for very cold temperature applications is not completely understood. The goal of this project is to confront actual theories to experimental results for mechanical properties of unidirectional glass-epoxy compos...
Thesis
Operation of wind turbines in a northern climate presents several challenges. For example, durability of composite materials, as those used in turbines blades, in such an environment is not guaranteed as the behaviour of these materials in severely cold regions is not completely understood. Therefore, the goal of this project is to confront actual...
