Enzymatic bonding methods, based on laccase or peroxidase enzymes, for lignocellulosic products such as medium-density fiberboard and particleboard are discussed with reference to the increasing costs of presently used petroleum-based adhesives and the health concerns associated with formaldehyde emissions from current composite products. One approach is to improve the self-bonding properties o...

The effects of wollastonite nanofibers on the physical and mechanical properties of particleboard were studied. Nano-wollastonite (NW), with the size range of 30 to 110 nm, was applied at 5, 10, 15, and 20%, based on the dry weight of wood chips, and compared with control specimens. Two application methods of NW were used: surface application (SA) and internal application (IA). Density was kept...

This study reviews world literature on the strength-related effect of duration and rate of loading on wood and wood-based materials. Also, early developments are discussed which led to the currently used permanent loading factor of 9/16. Published data on duration of load are reanalyzed and compared. The comparisons suggest that the effect of stress level on duration of stress for wood is great...

Wood based panels are composed of wood or other lignocellulosic material broken down into small elements and then reconstituted to form new products using different binders under pressure and heat. Production of wood composites such as particleboard and fiberboard has been constantly increasing in the U.S. for the last 25 years. Both panel products are extensively used as a raw material in the ...

Oriented strand board (OSB) is a commonly used structural wood-based panel for walls and roof siding, but recently the industry has become interested in OSB as substrate indoor outdoor furniture. Particleboard mainly furniture productions popular construction material due to its numerous usage possibilities inexpensive cost. Moisture one of most important factors affecting performance post-trea...
