Heat treatment is usually applied to wood species to improve their properties. This study examined the effects of heat treatment on compression and bonding strength properties of Scotch pine (Pinus sylvestris L.), which has industrially high usage potential in wood working industry. Test samples were exposed to heat treatment under varying temperatures (110, 130, 150 and 170°C) for varying durations (2 and 6 h.). Compression and bonding strength tests were performed according to TS 2470, BS EN 204 respectively. The test results showed that the highest bonding strength (8.26 N/mm2) was obtained from control samples. The highest value of compression strength was measured as 60.47 N/mm2 in heat treated samples (150°C-2 h.) It can be said that the heat-treatment process was affected on the mechanical properties of wood materials.

Isyl i?lem genellikle ah?ap malzemenin özelliklerini iyile?tirmek için uygulanyr. Bu çaly?mada, ah?ap sektöründe yaygyn olarak kullanylan saryçam (Pinus sylvestris L.) odununda ysyl i?lem uygulamasynyn basynç ve yapy?ma direnci gibi bazy mekaniksel özelliklere etkisi incelenmi?tir. Test örnekleri 2 ve 6 saat süre ile 110, 130, 150 ve 170°C sycaklykta ysyl i?leme maruz byrakylmy?tyr. Test örneklerinde basynç ve yapy?ma direnci deneyleri syrasyyla TS 2470, BS EN 204 standartlaryna göre yapylmy?tyr. Deney sonuçlaryna göre, en yüksek yapy?ma direnci de?eri kontrol örneklerinde (8.26 N/mm2), en yüksek basynç direnci de?eri ise 60.47 N/mm2 olarak ysyl i?leme tabi tutulmu? örneklerde belirlenmi?tir. (150°C-2 h.) Isyl Y?lem uygulamalarynyn ah?ap malzemenin mekanik özellikleri üzerine etkili oldu?u söylenebilir.
