For aluminum bonded joints a glycidoxypropyltrimethoxysilane--epoxy silane (Silqeust A-187 Silane, Momentive Company, USA), was used as a primer to chemically modify the aluminum
adherends.

adherend stiffness, International Journal of Fracture, 88(4):305-314.
Because physical and elastomechanical properties of the
adherend are changed by wood modification, it is hypothesized that surface processing causes differentiating surface textures.
Adherend material is aluminum alloy 7075-T6 plate with 2mm thickness and epoxy based Araldite 2011 is used for the bonding of the substrates.

adherend. In: Treatise on Adhesion and Adhesives.
The numerical simulation of bonded assembly in three-dimensional is known delicate for reasons related to the mesh at the interface between adhesive and
adherend plats, especially when dealing an elastic-plastic material of adhesive and the substrates.
However, the adhesion between the adhesive and the backing is still important in that a low level of adhesion at this locale would result in transfer of the adhesive from the backing to the
adherend.
Therefore, the information above illustrates the different patterns between PRF- and PU- bonded wood samples in terms of wood failure: PU adhesive may result in more cohesion or adhesive-adherend failure, whereas PRF adhesive results in more
adherend failure or wood failure.
