Silanes have potential for modifying wood materials to improving their properties. The aim of this study was to determine the physical and mechanical properties of beech (Fagus orientalis Lipsky) and fir (Abies bornmülleriana Mattf.) wood samples impregnated with gamma-aminopropyltriethoxysilane (APTES) as well as their performance against decay fungi. Beech and fir wood samples were impregnated with APTES at 20% and 40% concentrations. Control and treated samples were subjected to water uptake, bending strength and thermogravimetric analysis (TGA) tests as well as exposure to the white-rot fungus Trametes versicolor and the brown-rot fungus Coniophora puteana. Weight percentage gain (WPG) was higher in fir samples than in beech samples after APTES treatment. Water uptake was higher in fir samples than beech for control and impregnated samples. Water uptake decreased with higher APTES concentrations. APTES treatment slightly increased modulus of rupture (MOR) and modulus of elasticity (MOE). Mass loss caused by decay fungi was much lower in APTES treated timbers.

Silanların ahşap malzemeyi modifiye etme ve özelliklerini iyileştirme potansiyeline sahip olduğu bilinmektedir. Bu çalışmanın amacı gama-aminopropiltrietoksisilan (APTES) ile emprenye edilmiş kayın ve göknar odun örneklerinin fiziksel ve mekanik özellikleri ile birlikte çürüklük mantarlarına karşı performansını belirlemekti. Kayın ve göknar odun örneklerine APTES ile %20 ve %40 konsantrasyonlarda emprenye işlemi yapılmıştır. Kontrol ve emprenye edilmiş örnekler beyaz çürüklük mantarı Trametes versicolor ve kahverengi çürüklük mantarı Coniophora puteana'nın yanı sıra su alımı, eğilme mukavemeti ve termogravimetrik analize (TGA) tabi tutuldu. Yüzde ağırlık artışı, APTES ile emprenye işleminden sonar göknar örneklerinde kayın örneklerinden daha yüksekti. Kontrol ve emprenyeli örneklerde, kayın odununa göre göknar örneklerinde su alımı daha yüksek elde edilmiştir. Daha yüksek APTES konsantrasyonunun su alımını azalttığı bulunmuştur. APTES emprenyesi kırılma modülünü ve elastikiyet modülünü biraz artırdı. Çürüklük mantarlarının neden olduğu kütle kaybı APTES emprenyesiyle önemli ölçüde iyileştirildi.
