The density of wood varies with species. The density of a wood correlates with its strength (mechanical properties). For example, mahogany is a medium-dense hardwood that is excellent for fine furniture crafting, whereas balsa is light, making it useful for model building. One of the densest woods is black ironwood.
Delignification alters the mechanical, thermal, optical, fluidic and ionic properties and functions of the natural wood and is an effective approach to regulating its thermal properties, as it removes the thermally conductive lignin component, while generating a large number of nanopores in the cell walls which help reduce temperature change ...
A sample of MDF. Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. [ 1 ] MDF is generally denser than plywood.
Wood is an example of an orthotropic material. Material properties in three perpendicular directions (axial, radial, and circumferential) are different. In material science and solid mechanics, orthotropic materials have material properties at a particular point which differ along three orthogonal axes, where each axis has twofold rotational ...
Transparent wood composites are novel wood materials which have up to 90% transparency. Some have better mechanical properties than wood itself. They were made for the first time in 1992. These materials are significantly more biodegradable than glass and plastics. [1][2][3] Transparent wood is also shatterproof, making it suitable for ...
Wood physics encompasses critical research areas including: a) examining wood behaviour in relation to moisture, which involves fundamental aspects of moisture absorption, swelling, and shrinkage, b) investigating the impact of temperature on wood properties, encompassing heat conduction and heat storage, and c) assessing the mechanical ...
Tonewood refers to specific wood varieties used for woodwind or acoustic stringed instruments. The word implies that certain species exhibit qualities that enhance acoustic properties of the instruments, but other properties of the wood such as aesthetics and availability have always been considered in the selection of wood for musical ...
Cross-laminated timber (CLT) is an engineered wood product that is gaining popularity in the construction industry due to its numerous advantages, such as sustainability, cost-effectiveness, and ease of construction. Mechanical properties, particularly compressive strength, are key factors to consider when designing and constructing CLT panels.
