- Effect of ultra-low temperature on some mechanical properties of painted and film-coated plywood Mustafa Oncel Osman Emre Ozkan Agrociencias birch Bending plywood modulus of elasticity tensile shear strength Plywood is used for insulation systems in liquid natural gas cargo ships because of its good thermal properties. However, there are only a few research investigating the mechanical properties of plywood exposed to ultra-low temperatures. This study aims to determine how plywood reacts when exposed to ultra-low temperatures, such as - 196 °C. To achieve this purpose, the present study investigated the bending strength, modulus of elasticity, and tensile-shear strength of painted and film-coated plywood under ultra-low temperatures. The mechanical properties of plywood were discovered to be significantly impacted by the ultra-low temperature as a result of this research. Moreover, not only the bending strength of the painted and film-coated plywood increased with decreasing temperature, but also the modules of elasticity of the painted and film-coated plywood increased. At decreasing temperature, the tensile shear strength of the painted and film-coated oven-dried plywood increased, but the ensile-shear strength of painted and film-coated air-dried plywood decreased. The tensile shear strength of air-dried plywood was determined to be more sensitive to the temperature change. Therefore, attention should be paid to plywood used in liquefied natural gas cargo ships with high humidity. 2023 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48575202022 https://www.redalyc.org/journal/485/48575202022/ https://www.redalyc.org/journal/485/48575202022/html/ https://www.redalyc.org/journal/485/48575202022/48575202022.epub https://www.redalyc.org/journal/485/48575202022/movil 10.4067/s0718-221x2023000100422 en http://www.redalyc.org/revista.oa?id=485 Maderas.
