Plywood manufacture for the shipbuilding industry : multi-scale characterisation and understanding of wet maritime pine adhesion phenomena

The subject of this work is the manufacturing of green-glued plywood panels for the interior and the plating of a ship. The vacuum-moulding process is chosen to produce panels by assembling maritime pine veneers in the wet state with polyurethane adhesive. A study has been done to fix the parameters for gluing so that the manufactured plywood can answer to the mechanical characteristics required by the shipbuilding sector. The effect of several gluing parameters on the panel's mechanical properties is determined by an experimental design method. The wood moisture content when gluing and the amount of adhesive applied are mainly studied. The plywood panels' mechanical characterisations are realised using standardised shear tests and bending tests. In addition to the mechanical tests, wettability measures and bond lines microscopic observations provide a better understanding of the physic-chemical phenomena of green wood gluing. The material defined in this study is implemented in a boat hull prototype.
