Abstract The performance of engineered wood products is highly associated with proper bonding and an efficient cutting
method. This paper investigates the influence of CO2 laser cutting on the wetting properties, the modified chemical component of the laser-cut surface, and the strength and adhesive penetration near the bondline. Beechwood is cut by the laser with varying processing parameters, cutting speeds, gas pressures, and focal point
positions. The laser-cut samples were divided into two groups, sanded and non-sanded samples. Polyvinyl acetate
adhesive (PVAc) was used to bond the groups of laser-cut samples. After assembly with cold pressing, the tensile
shear test was… More >
