Abstract

This paper presents the analysis of the infl uence of conventional hot (CH) and high frequency (HF) gluing on relevant physical and mechanical properties of Laminated Veneer Lumber (LVL) made from beech peeled veneer with the thickness of 2.1 mm. Student’s T-test was applied to determine the signifi cance of differences between mean values of results obtained for the two different treatments. A signifi cant difference has been determined for the thickness loss, density, moisture and bending strength, while no statistically signifi cant difference has been established for the modulus of elasticity and shear strength of gluing between the means of the tested samples.

Secondary title:	Utjecaj tehnologije lijepljenja na fizikalna i mehanička svojstva lamelirane drvne građe
Secondary abstract:	U radu je istraživan utjecaj klasičnoga vrućeg (KV) i visokofrekventnog (VF) lijepljenja na neka relevantna fizikalna i mehanička svojstva uzoraka lamelirane drvne građe (LVL) dobivene od listova ljuštenoga bukova furnira debljine 2,1 mm. Prikazani su i analizirani dobiveni rezultati. Primijenjen je T-test za određivanje značajnosti razlike artimetičkih sredina dvaju skupova uzoraka. Za smanjenje debljine, gustoću, sadržaj vode i čvrstoću na savijanje utvrđena je signifi kantna razlika, a za modul elastičnosti i čvrstoću lijepljenja nije utvrđena signifi kantna razlika artimetičkih sredina ispitivanih uzoraka izrađenih primjenom različitih tehnologija lijepljenja.
