# Evaluation of Oak-Specific Consumption, Efficiency, and Losses from an Aesthetic Veneer Factory
## 1 Introduction
[12] conducted research on the impregnation of beech veneers with low- and medium-molecular-weight phenol-formaldehyde solutions. Low-molecular-weight phenol-formaldehyde-impregnated veneers showed a higher modelling than high-molecular-weight veneers. [PERSON] and [PERSON] [13] showed that, in order to increase the casting performance, the veneer samples were impregnated with furfuryl alcohol for improved plasticization. The degree of plasticization of furfuryl alcohol is comparable to the use of water. [PERSON] and [PERSON] [14; 15] studied the comparison of veneer subjected to mechanical tests, respectively, parallel and perpendicular strengths on fibers. The modulus of elasticity perpendicular to the fibers was smaller than that parallel to the fibres. [PERSON] et al. [16] presented the importance of optimal heating temperatures by soaking beech, birch, and spruce. It is necessary to heat the green wood before peeling to improve the peeling process, as well as the quality of the veneer. [PERSON] et al. [17] highlighted the importance of tensile and shear tests for veneers under normal conditions but also immersed in water. [PERSON] et al. [18] investigated the effects of disposing of different black alder and poplar veneers by replacing birch veneer in plywood with cores of alternately growing species. The results showed that alder and birch plywood have the highest bending strength. The birch veneer had an adhesive consumption of 152 g/m\({}^{2}\), while the trembling poplar veneer had an adhesive consumption of 179 g/m\({}^{2}\). The low-density wood veneer had a higher consumption of adhesive. [PERSON] et al. [19] presented the importance of used veneers and cutting speed, but also the importance of veneer preconditioning inside of veneer technology. [PERSON] and [PERSON] [20] presented the importance of water jet cutting as a possible alternative to traditional cutting methods. The width of the veneer decreased as the water jet propagated into the material. [PERSON] et al. [21] presented the modification of the flexibility of the decorative veneer with the help of plastic foil. This method is effective because it widens the application area and the strength of the veneer decreased when its moisture content was higher than 20%. [PERSON] et al. [22] presented the importance of the development of veneer-based wood composites due to the high flexibility of design and mechanical strength compared to solid wood. The study showed the influence of veneer thickness on tensile strength compared to solid wood. Ropes with a thickness of 0.5 mm, 1 mm, and 1.5 mm and thin timber with a thickness of 1.5 mm, 3 mm, and 5 mm were used. From the experimental results it was concluded that the tensile strength was 70% higher than veneer lumber. [PERSON] et al. [23] presented the properties of plywood made of densified and un-densified veneer. The plywood was made of black alder and birch veneer, using urea formaldehyde (UF). MOE increased with increasing plywood density. The increase in veneer density led to a decrease in MOR. The temperature of 150 \({}^{\circ}\)C for the densification of the veneer was sufficient to obtain improved plywood properties. [PERSON] et al. [24] presented the characteristics of beech and poplar wood plywood, with thicknesses of 6 mm, 10 mm, and 18 mm, when vinyl acetate was used for gluing. The study concluded that the use of carbon fibre and fiberglass led to increased plywood performance. [PERSON] et al. [25] presented the evaluation of the potential use of the wood species _Scizolobium parahyba_ in the production of laminated veneer lumber LVL. The non-destructive wave test method was used to determine the EdV (dynamic veneer modulus). The authors noted that the higher the EdV values, the higher the mechanical strength values of the LVL. [PERSON] et al. [26] analyzed the effect of veneer densification on the change of temperature inside the plywood during the hot-pressing stage. Birch veneer and phenol-formaldehyde resin were used to make the plywood samples.
