Abstract In the process of wood bonding, usage aged and inactivated wooden elements can cause a reduction in mechanical properties products containing wood-adhesive joints. Treating with an atmospheric air plasma represents sophisticated technique for surface activation. With this regard, to enhance bondability normal beech ( Fagus sylvatica L.) urea-formaldehyde (UF) adhesive, dielectric barri...

The work described here is an uHrasonies based experimental study which aims to address the lack of a reliable technique for detecting strength loss in adhesive joints after exposure to hot wet environments. This is manifested as a change in the failure mode of an adhesive system from a cohesive failure in the as-made condition, that is failure through the adhesive, to an adhesive failure, fail...

Adhesive bonding of aluminum holds some possible advantages over the traditional methods of construction in the aerospace industry. However, there is uncertainty about the mechanism of adhesive bonding and the changes occurring during environmental attack which reduce the bond strength. An improved understanding will aid in the development of better techniques for non-destructive testing (NDT) ...

A three-dimensional finite element modeling is developed using ABAQUS software. This includes riveted and rivet-bonded joints models. Both models undergo thermal heat caused by hot-driven rivet process and then are subjected to a constant velocity at one of its strip edges to simulate the shear tensile test up to the failure point. The developed FE models were based on elastic-plastic propertie...

The demand for volume deployment of photonic components has increased, and with it the need to effectively manufacture in a reproducible and cost effective way. Therefore, it is important to keep the assembly process consistent and stable. A simple shear test setup was used in this study to determine the shear force that can be used as an instant indicator to the process stability of fiber arra...

Adhesively bonded structure and bonded composite repairs are often exposed to aviation fuel during service. A relatively limited number of studies examining the influence of fuel and the many additives it contains have been made. The current report details experimental studies that have examined the influence of fuel and common additives such as lubricity and deicing agents on the fracture toug...
