Ahşap, yaygın olarak kullanılan en eski yapı malzemelerden birisidir. Farklı alanlarda da farklı amaçlarla kullanımına yönelik giderek artan bir talep vardır. Bu talebi karşılayabilmek için ahşap esaslı yapısal kompozitler geliştirilmiştir. Bu çalışmada, ısıl işlem uygulanmış ve fenol formaldehit (FF) tutkalı kullanılarak karbon ve cam elyaf ile güçlendirilmiş kayın (Fagus orientalis Lipsky) kompozit örneklerin bazı fiziksel ve mekaniksel özellikleri araştırılmıştır. Bu amaçla ahşap malzemelere 150, 175 ve 200°C sıcaklıkta 3 saat süre ile ısıl işlem uygulanmış ve deney örnekleri hazırlanmıştır. Test sonuçları, karbon ve cam elyaf ile güçlendirilmiş örneklerin eğilme direnci (MOR) ve eğilmede elastikiyet modülü (MOE) değerlerini artırdığını göstermiştir. Bununla birlikte liflere paralel basınç direnci (CS//) değerlerinde, uygulanan ısıl işlem sıcaklığına ve güçlendirici malzeme türüne göre önemli değişikliklere neden olurken, liflere paralel yapışma direnci (SS) değerlerinde düşüşler belirlenmiştir. Genel olarak, karbon fiber ile güçlendirilmiş deney örneklerin MOR ve MOE değerleri, cam elyaf ile güçlendirilmiş örneklerden daha yüksek, CS// ve SS değerleri ise daha düşük belirlenmiştir.
