Outline of Final Research Achievements

Manufacturing technology of thin veneer multiple laminated materials with small amount spreading system of adhesive were investigated.
The micro multiple laminated materials made with Sugi veneers of 0.3mm thickness and phenol formaldehyde resin of 6g/m2 spreading rate had 2mm thickness and 0.4g/cm3 specific gravity. The mechanical properties of the materials with orthogonal laminate were as same as commercial Sugi plywood. The modulus of rapture of the materials was improved up to 100MPa by oriented laminating. As more practical technology, such as the new type small amount spreading system of adhesive and the manufacture technique like pre-impregnation technique to call "Prepreg" has been developed.
