Abstract

Laminated wood-ceramics were created from beech veneer by impregnation with phenol formaldehyde resin and airtight sintering. The resulting laminated biocarbon material exhibited a clearly layered structure and partially preserved microstructural characteristics of normal wood. Laminated structure and airtight sintering techniques significantly affected basic material properties. Carbon yield can increase and sintering cost can decrease through these methods. The material treatments used generate porosity, density, and volumetric shrinkage properties that are different from composites that are vacuum-sintered. Its layered structure is associated with the stacking of veneers. The fracture toughness increases to 0.6-1.2 MPa·m1/2 because of the laminated structure, and the material exhibits a progressive failure behavior.
