Abstract
A method of making a sandwich-type, compression-molded, composite component having improved surface appearance is provided. Reinforced thermoplastic skins, first and second sheets of thermoplastic adhesive and a cellulose-based core of a blank or stack of sandwich materials are heated to a softening temperature of the thermoplastics. The heated blank or stack is allowed to cool in the mold cavity until inner surfaces of the skins are bonded to top and bottom surfaces of the core by the sheets to seal core cavities. Air in the sealed cavities urges softened portions of the sheets and portions of the core inwardly towards the cavities of the core as the air in the cavities cools to inhibit debossing and improve surface appearance of a first outer surface of the blank or stack.
