Mechanical Performance of Woodwork Joinery Produced by Industrial Methods

Altunok M, Kureli I, Doganay S and Onduran A

In this study, the improvement of the mechanical properties of wood material were investigated to determine the effects of heat treatment (thermo-process) and impregnation processes held in open-air conditions on the mechanical performance of woodwork joinery. To this end, pine (Pinus sylvestris L.) and chestnut (Castanea sativa) species grown in our country were used which have significant natural and commercial value. Actual sizes of the examples of woodworks were set out diagonally.

In the double-tenon construction and glue type polyurethane (PU) and D4 adhesives used. Diagonal woodwork and the test samples prepared by class at 185°C temperature with a thermo-vapor process protections apply. Thus, thermo-treated wood joinery was obtained. After application of the heat treatment by immersion, the test samples, and a 5% solution of tannin and oak with a natural pine cone resin made impregnation process. Then, the impregnation of natural wood (control) only heat-treated and heat treatment+impregnated samples kept for one year in outdoor conditions. At the end of the waiting period, on samples prepared by the principles stated in TS 2472 and TS 7251 EN 107 standard “Windows-Test Methods-Mechanical Experiments,” according to the principles specified in standard performance tests (diagonal compression test, windows hang test) and microscopic observations and investigations to determine the cellular changes were made. These observations suggest that the natural form treated and untreated samples and comparison of window wings holding the external environment gained strength during the degradation and the reasons for this deterioration was detected against the impregnated material. Experimental density measurements on samples without waiting in outdoor conditions before, after waiting and waiting, as periodic process was determined by performing the difference.

In this study, experiments were carried out on diagonal examples and especially examples in actual size woodwork. In addition, natural oak tannin solution impregnation process was used. From previous research literature diagonal examples have been used not only in instances of life-size woodwork. In addition, thermo-transaction and impregnation process used in conjunction studies, natural pine resin is used, and there is no such study created a solution. This also shows that the original value of our work.
