Experimentation on adhesion of epoxy

In a recent article (Sekulic and Curnier (2007) [1]), an original axisymmetric epoxy-stamp on glass-disc specimen, which exhibits stable debonding, was presented for identifying the adhesive properties between epoxy and glass, namely interface debonding en ...

Fracture of adhesively-bonded pultruded GFRP joints under constant amplitude fatigue loading

Yi Zhang, Thomas Keller, Anastasios Vassilopoulos

The fracture behavior of adhesively-bonded structural joints under tensile constant amplitude fatigue has been investigated. Double-lap joints (DLJs) and stepped-lap joints (SLJs) composed of pultruded GFRP laminates and an epoxy adhesive were examined. Bo ...

Vacuum-bag processing of sandwich structures: role of honeycomb pressure level on skin-core adhesion and skin quality

Véronique Michaud

Non-autoclave processing of honeycomb sandwich structures generally leads to poor compaction and high porosity of the skins, along with a decreased skin-core adhesion. The pressure level inside the honeycomb cells plays an important role and is controlled ...

Design of robust and ductile FRP structures incorporating ductile adhesive joints

Thomas Keller, Julia De Castro San Roman Fest

A design concept for engineering structures consisting of brittle FRP components and ductile adhesive joints is proposed. The elastoplastic adhesive joints provide system ductility that compensates for the material ductility that FRP composites lack. In th ...

Fracture and Fatigue of Adhesively-Bonded Fiber-Reinforced Polymer Structural Joints

Ye Zhang

Being good structural replacement for other conventional material, the pultruded glass fiber reinforced polymer (GFRP) profiles are being increasingly used in civil engineering structures. The connection between components is considered the most suspect ar ...

Strengthening of flat slabs against punching shear using post-installed shear reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz

A significant number of existing flat slabs currently require strengthening against punching shear for safety reasons (the increase of applied loads and deficiencies during design or construction) or to comply with more stringent code requirements. Availab ...

Effects of low and high temperatures on tensile behavior of adhesively-bonded GFRP joints

Yi Zhang, Thomas Keller, Anastasios Vassilopoulos

The tensile behavior of adhesively-bonded double-lap joints composed of pultruded glass fiber-reinforced adherends and an epoxy adhesive was investigated under temperatures ranging between -35°C and 60°C. The load-elongation response was influenced primari ...

Estimation of interfacial fracture toughness based on progressive edge delamination of a thin transparent coating on a polymer substrate

Yves Leterrier

Evaluation of interfacial toughness of sub-micron-thickness layers deposited on a ductile substrate is a challenging task which has motivated different experimental approaches Fragmentation testing was used in the present study as a means of interface char ...

Optimum thickness of joints made of pultruded GFRP adherends and polyurethane adhesive

Thomas Keller, Till Vallée

This paper presents results of experimental and numerical investigations on double-lap joints composed of pultruded GFRP profiles and polyurethane adhesive subjected to quasi-static axial tensile loading. The objective was to investigate the effect of the ...

Optimisation of low pressure processing for honeycomb sandwich structures

Sandra Sequeira Lopes Tavares

Vacuum-bag processing of honeycomb sandwich structures faces particular challenges compared to autoclave sandwich fabrication for aeronautics, a consequence of using, at the most, atmospheric pressure for their manufacturing. In particular, the adhesion of ...
