In this research, a series of wood-based panels were produced by using wood chips [beech (Fagus Sylvatica L.) and Scotch pine (Pinus sylvestris L.)] as wastes of wood-working workshops and acrylic fibers as wastes of textiles factory. Four kinds of different panels (Eltapan I, II, III and IV) were obtained by mixing these components in different composition (0%, 25% and 50%). Some physical and mechanical properties of the samples taken from these panels were determined in accordance with ASTM D1037-12 and ASTM-C 1113. The values were compared to properties of industrially produced chipboard. As a result, the textile fibers used as additive material reduced density, thermal conductivity and bending resistance of wood panel and increased dimensional stability of wood panel.

The most objectionable environment for wood is outdoor conditions. In this study, test specimens prepared from chestnut wood (Castanea sativa Mill) were impregnated with natural and chemical impregnation agent. It was aimed to determine the effect of outdoor conditions on physical and mechanical properties of wood material by keeping them under these conditions for one year. As natural impregnation material pine tannin and acorn tannins, as chemical impregnation material imersol aqua and timbercare aqua were used. The retention amount, air-dried density, bending strength, modulus of elasticity, compression strength parallel to fibers, adhesion strength parallel to fibers, screw withdrawal strength were determined. As a result, it can be said that the physical and mechanical test values can compare wood impregnated with natural impregnation materials to wood impregnated with chemical impregnation materials after one year exposed to outdoor conditions.

Açık Koşullarına Bırakılan Doğal ve Kimyasal Maddelerle Emprenye Edilen Kestane Odununun BazıFiziksel ve Mekanik Özellikleri ÖZ Ahşap koruyucular, ahşabın kullanım ömrünü uzatmak için yaygın şekilde kullanılmaktadır. Ağaç için en sakıncalı ortam açık hava koşullarıdır. Bu çalışmada, kestane (Castanea sativa Mill) ağacından hazırlanan örnekler doğal ve kimyasal emprenye maddesi ile emprenye edilmiştir. Açık hava koşullarının ağaç malzemenin fiziksel ve mekanik özelliklerine etkisini, bir yıl boyunca bu koşullar altında tutarak belirlenmesi amaçlandı. Doğal emprenye materyali olarak çam taneni ve meşe palamudu taneni, kimyasal emprenye maddesi olarak imersol aqua ve timbercare aqua kullanılmıştır. Retensiyon miktarı, hava kurusu yoğunluk, eğilme direnci, elastikiyet modülü, liflere paralel basınç direnci, liflere paralel yönde yapışma direnci, vida tutma direnci belirlenmiştir. Sonuç olarak, doğal emprenye maddeleriyle emprenye edilen ahşap malzemelerin kimyasal emprenye maddeleri ile emprenye edilen ahşap malzemeler ile bir yıl süreyle açık hava koşulları altındaki değerlerin mukayese edilebilir düzeyde olduğu söylenebilir.
