Abstract :This study was performed to determine the effects of heat treatment on weight loss during combustion of the laminated wood materials produced from Oriental beech ( Fagus orientalis L.), scotch pine ( Pinus sylvestris L.), sessile oak ( Quercus petraea L.), and poplar ( Populus nigra L.) veneers bonded with PVAc-D 4 , PUR and MF adhesives. For this aim, the weight loss during combustion of the test samples was determined according to ASTM E 160-50. The results of this study indicated that the weight loss percentage was the highest in poplar wood (89.17%), PVAc-D 4 adhesive (89.79%) and control samples (88.69%). In the interaction of the wood materials and type of adhesive, the highest value was measured in poplar+PUR (90.93%), interaction of the wood materials and heat treatment in poplar + control samples (90.87%), in the interaction of the type of adhesive and heat treatment in PVAc-D 4 + 185 °C (91.10%). In the interaction of the wood material, type of adhesive and heat treatment temperature, the highest value was determined in laminated control poplar samples with PUR adhesive (93%), while the lowest in laminated scotch pine samples with MF and heat-treated at 185 °C (81.83%). The use of laminated and heat-treated wood material in places where in high risk of fire, impregnation of wood material with fire-retardant compounds can be suggested.Keywords : Heat treatment, weight loss, combustion, adhesive, wood material
