Abstract

In this study, the influence of Furfurylation on practical properties of beech plywood investigated. Furfurylation of beech layers were performed by impregnation and heat catalyze up to 30% and 70% weight percent gain. Plywood specimens made by 2 resins (Urea Formaldehyde and Methylene Diphenyl Diisocyanate). Practical properties of furfurylated specimens investigated and compared to untreated specimens. Modulus of rupture (MOR), modulus of elasticity (MOE), shear strength, water absorption and thickness swelling were determined. Results revealed that by increasing the furfurylation level, modulus of elasticity (MOE), water absorption and thickness swelling (dimensional stability) improved. But modulus of rupture (MOR) just increased up to 30% furfurylation and decreased in higher levels of furfurylation. Furfurylation had a negative effect on shear strength of bond line and decreased by increasing the furfurylation level.
