Formation of N-nitrosamines by micelle-catalysed nitrosation of aliphatic secondary amines

Urs von Gunten, Florian Frédéric Vincent Breider, Isuf Salihu

N-Nitrosamines are an important class of potent human carcinogens and mutagens that can be present in water and wastewater. For instance, N-nitrosamines can be formed by reaction of nitrosating agents such as NO+ or N2O3 formed from nitrite under acidic co ...

Damage recovery after impact in E-glass reinforced poly(epsilon-caprolactone)/epoxy blends

Véronique Michaud, Amaël Maximilien Cohades

Damage recovery after low-velocity impact has been assessed in woven E-glass fibre-reinforced polymer composites with an epoxy matrix and a blend of epoxy and 25 vol% of poly(e-caprolactone) (PCL). Impact was carried out at three energy levels (8.5, 17, 34 ...

Thermal mending in E-glass reinforced poly(epsilon-caprolactone)/epoxy blends

Véronique Michaud, Amaël Maximilien Cohades

Blends of difunctional epoxy monomer with a 4,4'-diaminodiphenylsulfone hardener and poly(epsilon-caprolactone) (PCL) were used as a self-healing matrix in woven glass fibre-reinforced polymer composites (FRPs). FRPs with these blends (containing 0, 25 and ...

Fracture mechanics-based progressive damage modelling of adhesively bonded fibre-reinforced polymer joints

Thomas Keller, Anastasios Vassilopoulos, Moslem Shahverdi, Roohollah Sarfaraz Khabbaz, Aida Cameselle Molares

A quasi-static progressive damage model for prediction of the fracture behaviour and strength of adhesively bonded fibre-reinforced polymer joints is introduced in this paper. The model is based on the development of a mixed-mode failure criterion as a fun ...

Relief of edge effects in bi-adhesive composite joints

Seyed Abdolmajid Yousefsani

Three-dimensional thermo-mechanical stress analysis of composite joints with bi-adhesive bonding is presented using the full layerwise theory. Based on three-dimensional elasticity theory, sets of fully coupled governing differential equations are derived ...

Ductility of adhesively bonded timber joints

Thomas Keller, Anastasios Vassilopoulos, Myrsini Angelidi

In the field of timber engineering, adhesive bonding remains a promising, though poorly developed, joining technique that may increase the structural stiffness and capacity of timber joints and structures. Selecting ductile adhesives may further allow to c ...
