$a 3D formability of perforated materials based on veneer $f Jozef Fekiač, Jozef Gáborík, Mária Šmidriaková 215 $c Graf., obr., tab. 320 $a Lit. 330 $a The paper is focused on the impact of perforations on 3D-formability of two-layer birch veneer materials. Two-layer material consisted of one perforated and one solid veneer. The veneers were glued together with low density polyethylene film. The grain of veneers in the board ranat a 90 degree angle to each other. Veneer perforation was done using CO2 laser. Several perforation varieties were designed taking into account the shape of perforation, the direction of perforations with respect to the wood fibres and spacing between the perforations. 3D formability was determined by pressing a ball punch into the hole in the matrix and evaluated according to the detected deepening. The results indicate a negative impact of the perforations on 3D formability when compared to non-perforated material; only the variety with “I” shape perforations oriented parallel to wood fibres approached the non-perforated material. Lightening of the material was the secondary benefit of the perforations. 463 -1
