Mechanical Properties of Red Pine (Pinus brutia Ten.) depending on Bay Leaf (Laurus nobilis L.) Extract Treatment Level and Time

Abstract

The rapid depletion of forest and water resources, drought, climate change, and the significant loss of freshwater resources, along with fires and wars, necessitate the creation of healthy materials and a hygienic structure, as well as the optimal use of wood. This study used various processes to obtain extracts from laurel leaf waste, which is known for its antioxidant/antibacterial properties. Subsequently, solutions of various concentrations (1%, 3%, and 5%) were prepared and the wood was impregnated using the immersion method (short, medium, and long-term). Tests were then conducted to determine the retention, specific density, bending strength, modulus of elasticity, compressive strength, and dynamic bending. The highest retention was determined at a 5% concentration for 6 h (2.50%), the highest air-dry specific density was determined at 5% for 6 h (0.68 g/cm³), and the highest bending strength was determined at 5% for 6 h (143 N/mm²). The extract prepared from ecological bay leaf plant waste with water creates a partially hygienic (antioxidant/antibacterial) framework for organic wood, benefiting human and environmental health.
