The modification of wood with lamination, densification, and carbon fiber reinforcement treatments is aimed at improving its technological properties and optimizing its industrial applications. The objective of the research was to determine the densities and dynamic modules of solid, laminated, and reinforced wood of Cryptomeria japonica (sugi). Transverse vibration tests were performed using 36 small test specimens. The treatments of laminating, densifying, and reinforcing with carbon fiber increase the density and dynamic modulus of solid wood. This technological improvement is explained by the effect of densification, the epoxy resin as an adhesive, and the incorporation of carbon fiber as reinforcement. The magnitudes follow the statistical trends of those of woods reported in the literature.
