Influence of veneer perforation on 2D formability of two-layer material

The aim of the paper is to investigate the effect of different perforations in veneers on the 2D formability of two-layer material. Veneer perforation was done with a CO2 laser. The two-layer material was composed of two veneers, one perforated and one entire (non-perforated), the fibers in the veneers being perpendicular to one another, and was glued using a polyethylene film. The 2D (planar) formability of two-layer materials was detected by three-point bending load and evaluated through the minimum bending radius. The most significant improvement of formability wasobserved after perforation in the shape of the letter "I" at the perforation direction parallel to the wood grain.
