The adhesive bonding technique is employed from the aeronautical/aerospace industry to current house products. To comply with requirements of distinct applications, different joint configurations are available designer. While single-lap joints (SLJ) most common in application and research, double-lap joints, scarf T-joints find specific applications. seldom studied literature, but these used, f...

In this paper, the use of a cohesive-zone approach to model the mode-I fracture of adhesive joints made from a polymer-matrix composite is demonstrated. Cohesive-zone parameters were obtained by matching numerical results to experimental observations. It is shown that there is a distinction between the characteristic strength of the interface associated with the toughness, and the intrinsic coh...

Ultrasonic welding is a very promising technique for joining thermoplastic composite (TpC) components in aircraft primary structures [1, 2]. The potential introduction of new lightweight structures in civil aviation has been driving the change towards condition-based maintenance (CBM) as an alternative to the regular inspection interval approach [3]. In turn, CBM has been pushing forward the de...

Purpose The purpose of this paper is to evaluate and exploit the combination additive manufacturing polymeric technology structural adhesives. main advantage expand maximum dimension 3D printed parts, which typically limited, by joining parts with adhesive, without losing strength stiffness keeping major asset 3 D printing: freedom shape system low cost parts. Design/methodology/approach materi...

This work reports on the experimental and numerical study of the bending behaviour of two-dimensional adhesively-bonded scarf repairs of carbon-epoxy laminates, bonded with the ductile adhesive Araldite 2015. Scarf angles varying from 2 to 45o were tested. The experimental work performed was used to validate a numerical Finite Element analysis using ABAQUS and a methodology developed by the aut...

A novel semi analytical method is developed for transient analysis of single-lap adhesive joints with laminated composite adherends subjected to dynamical loads. The presented approach has the capability of choosing arbitrary loadings and boundary conditions. In this model, adherends are assumed to be orthotropic plates that pursuant to the classical lamination theory. Stacking sequences can be...

Prevailing trend towards the use of lighter and lower cost engineered plastics in automotive, construction, aerospace, electronics and other industrial end uses have created a need for pressure sensitive materials that can bond well to these new, inherently low surface energy plastics. Reported herein are novel all acrylic compositions with inherently lower surface energy that display significa...

Cost-effective rehabilitation and/or strengthening of steel structures currently demanded by the telecommunications industry and transportation departments. Rehabilitation is often required due to crosssection losses resulting from corrosion damage and strengthening may be required due to changes in the use of a structure. Current strengthening techniques, have several disadvantages including t...
