Investigation of the Physical and Mechanical Properties of Scotch Pine and Oak Woods Modified with Natural Preservatives in the Aging Process

J Appl Mech Eng,, cilt.12, sa.2, 2023 (Scopus)

In this study, scotspine and oak wood, which are grown in large areas of our country, have high commercial value and

are widely used at this rate, were modified with natural wood preservative solution. The protective feature of the

modification material against temperature, humidity and sun rays in the external environment was investigated.

Modification with a natural wood preservative solution was applied to B level samples of physical and mechanical

property determination test samples prepared from scotch pine and oak woods. The natural preservative solution was

obtained by extraction method from walnut bark and leaves. The preservative solution was impregnated with the

samples by immersion for 8 hours. Impregnated (B level) and non-impregnated (A level) samples were kept in

natural environment under seasonal effect for one year and natural aging was applied.

At the end of this process, the physical changes in the samples were examined by measurement and test method. As a

result, it has been determined that wood preservative protects the physical and mechanical properties of both wood

species, reduces the loss (change) in these properties, and reduces the shape deformation.
