Structural Properties of Processed Wood

Processing wood significantly enhances its structural properties, leading to improved performance in various applications. By altering the wood’s cellular structure and composition, processing methods can increase its strength, stiffness, and durability.

Strength

Processed wood exhibits increased strength compared to raw wood. The removal of defects, such as knots and voids, during processing results in a more uniform material with fewer weak points. Additionally, the application of pressure and heat during processing densifies the wood, increasing its resistance to bending, compression, and tension.

Research conducted by the University of British Columbia found that laminated veneer lumber (LVL), a processed wood product, had a bending strength 1.5 times greater than solid wood.

Stiffness

Processing also improves the stiffness of wood, making it more resistant to deformation under load. The removal of moisture and the alignment of wood fibers during processing increase the material’s rigidity. As a result, processed wood can withstand higher loads without bending or warping.

Studies by the Forest Products Laboratory have shown that oriented strand board (OSB), another processed wood product, has a stiffness modulus 20% higher than plywood.

Durability

Processed wood is more durable than raw wood due to its enhanced resistance to moisture, decay, and pests. The removal of moisture and the application of preservatives during processing reduce the susceptibility of wood to rot and decay. Additionally, the densification of wood during processing makes it less susceptible to insect and fungal attacks.

Tests conducted by the American Wood Protection Association have demonstrated that pressure-treated lumber, a processed wood product, has a lifespan of over 50 years in outdoor applications.

Factors Influencing Structural Integrity

The structural integrity of processed wood is influenced by several factors, including:

• Type of processing method
• Wood species
• Processing parameters (e.g., pressure, temperature, moisture content)
• Quality of raw materials
• Post-processing treatments (e.g., preservative application)
