EFFECT OF SURFACE ROUGHNESS ON WOOD BONDING STRENGTH

1. Murčo Obućina, Federation of Bosnia and Herzegovina , Bosnia and Herzegovina

This paper presents research impact planed surface roughness of beech, fir, oak and thermally modified beech-wood (220 oC) samples, the strength of bonding. The samples were planed in the radial direction. Tools for planing had a double-edged, planed and the displacement at a speed of 12 m / min. The depth of the milling operation was 1.00 mm, rake angle blade tool was γ = 15 °. at 5000 ° / min. Diameter of the cutting edge was Φ = 125 mm. Surface roughness is measured by the length of treatment using an electrical-mechanical profilmetra Mitutoyo SJ-201. Samples were glued with PVAc glue. The lowest roughness had samples of oak, then fir and beech the highest, and thermally treated beech. The highest shear bond strength, they had samples of beech, followed by oak, fir, and had the lowest strength of
the samples we did thermally modified beech
