A Method to Ensure Long-term Adhesion Quality of Al-LDPE-Al Hybrid Sandwich Panels



The adhesion problem of aluminum polyethylene sandwich panels is analyzed within the scope of this study. The theoretical necessary adhesion value for maximum shear stress is calculated. A selected area of the panel is scanned with a peeling test. The set limit value of adhesion led to no customer claims within the observed period of six months. The condition of machine elements and the recycled material quality of polyethylene are also determined.
