Evaluation of Durability of Adhesive Joints in Sandwich Panels
Sandwich panels that are typically applied in side walls and roofs of light trucks, vans and recreational vehicles are evaluated on their durability under bending and torsion loads. The panels exist of a polyurethane foam core between GF-reinforced polyester skins, glued into aluminium corner profiles. The effect of ageing on the durability performance is evaluated as well. Both optimal bonded as well as deliberately delaminated panels are tested and the results show that all of them keep their structural integrity.
