Competition for the conventional supply of wood residue utilized
by the particleboard industry is increasing. Utilization of low
quality residues by the pulp and paper industry, new sawmill and
plywood recovery techniques, and the growing practice of converting
low quality residues into steam and electrical power have all cut into...
Nonlocal theories of continuum mechanics are used to model the
fracture behavior of particleboard in tension perpendicular to the plane
of the board. Classical theories of fracture are examined in comparison
to a nonlocal crack solution which has removed the stress singularity
at the crack tip. With the removal of...
Softwood plywood is one of the structural wood products studied in the CORRIM
II effort to document the environmental performance of wood product in residential
structures. Life-cycle inventory (LCI) models were developed to provide performance
data for plywood production by tracking all of its inputs and outputs in a gate-to-gate...
The objective of this study is to complete life cycle inventories (LCI) for laminated veneer lumber (LVL) and composite I-joist (I-joist) production in the two main forest products producing regions in the U.S., the Pacific Northwest (PNW) and Southeast (SE). LVL and I-joists are composite wood building materials that are...
This research provides state economic development planners and forest policy
makers with new economic information about the wood remanufacturing industry. An
overview describes each industry sector's employment, payroll size, and estimates of
annual growth rates. This helps planners determine which sectors are likely to provide
the most economic benefit to...
Dielectric quantification of material properties is a technology well established in many industries. The application of this concept to the forest products industry to measure adhesive cure, however, has been belated in part due to a lack of proven technology directed at industrial processes and products. It is of great...
The drying of wood is required in most forest products
manufacturing operations. Depending on the wood species,
dimensions, drying temperatures, and drying duration, the
amount of emissions and energy consumption can greatly affect
the operating cost, environment, and quality of wood dried.
As such, the forest products industry continues to...
Particleboard is a widely used composite panel product
consisting of consolidated wood particles and adhesive. On
a macro level the panel appears to be homogeneous, however,
its density varies both throughout the plane of the panel
as well as through its thickness. Of concern for this
thesis is the through-thickness...
Oriented strand board is a panel product used in
structural applications in home construction much like
plywood, yet little is known of the effect of temperature and
moisture content on its performance. The objective of this
study is to study these effects on oriented strand board and
for comparative purposes...
