Stress mitigation for adhesively bonded photovoltaics with fibre reinforced polymer composites in load carrying applications

Thomas Keller, Yu Bai

Structural loads, especially in-plane compression, may cause local buckling and debonding of the photovoltaic (PV) cells that are mechanically integrated with structural members and this may lead to degradation in their electrical performance. This paper p ...

Behavior of prestressed CFRP plates bonded to steel substrate: Numerical modeling and experimental validation

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

In recent years, retrofitting of steel structures has emerged as a major issue in structural engineering and construction management. As the adhesive bond is often the critical aspect controlling the actual performance of steel profiles externally strength ...

Durability of adhesively bonded joints between pultruded GFRP adherends under hygrothermal and natural ageing

Thomas Keller, Joào Pedro Girâo Meireles de Sousa

This paper presents an experimental and numerical study about the durability of adhesively bonded joints between pultruded glass fibre reinforced polymer (GFRP) adherends for civil engineering applications. Single lap joint (SLJ) specimens were manufacture ...

A comparative study of mode I delamination behavior of unidirectional glass fiber-reinforced polymers with epoxy and polyurethane matrices using two methods

John Botsis, Georgios Pappas

The mode I delamination behavior of a unidirectional glass-fiber reinforced polymer with a prototype elasto-plastic polyurethane matrix (GF/PU) was investigated and compared with that of glass/epoxy (GF/EP) using double cantilever beam specimens. Fracture ...

Quantifying uncertainties in contact mechanics of rough surfaces using the multilevel Monte Carlo method

Fabio Nobile, Sebastian Krumscheid, Valentine Ginette Madeleine Rey

We quantify the effect of uncertainties on quantities of interest related to contact mechanics of rough surfaces. Specifically, we consider the problem of frictionless non adhesive normal contact between two semi infinite linear elastic solids subject to u ...

Glass-free lightweight PV building elements: solutions to minimize weight and maximize durability

Ana Cristina Oliveira Martins

In densely populated countries, little free land is available for the deployment of photovoltaics (PV) in field installations. In addition, 40% of the world's demand for electricity is related to buildings. These facts provide a strong argument for the acc ...

Polymer brush interfaces for protein biosensing prepared by surface-initiated controlled radical polymerization

Harm-Anton Klok, Mark Billing, Michael Badoux

Thin polymer films that are able to bind proteins are of great relevance for a wide variety of biosensor and biochip applications. Some of these applications require films that have high protein binding capacities while others call for surfaces that allow ...

Microfluidic Fabrication of Capsule Sensor Platform with Double-Shell Structure

Esther Amstad

Metal nanoparticles are frequently employed for the colorimetric detection of specific target molecules using an aggregation-induced shift of the localized surface plasmon resonance. However, metal nanoparticles dispersed in bulk solutions are prone to be ...

Ductile adhesively-bonded timber joints - Part 1: Experimental investigation

Thomas Keller, Anastasios Vassilopoulos, Myrsini Angelidi

In the field of timber load-bearing structures, adhesive bonding is a promising joining technique that may increase the structural stiffness and capacity of timber joints and structures. The use of ductile adhesives may furthermore allow designing ductile ...
