  • An investigation into the dynamics of RF LVL pressing

    Creator:
    Rowell, Daniel Lee
    Abstract:
    The dynamics of radio frequency (RF) laminated veneer lumber (LVL) pressing are explored for the purpose of optimizing this process. The RF LVL press at the Albany Trus Joist plant is the focus of this investigation. The investigation first focuses on bond strength development characteristics of the Georgia Pacific adhesive...

  • Essential oil treatment of VTC wood

    Creator:
    Scouse, Adam A.
    Abstract:
    Western juniper and cinnamon essential oils were combined with ethanol at 2.5, 5, and 10% concentrations by weight and applied to hybrid poplar (Populus trichocarpa x P. deltoids) veneers by vacuum soaking to produce a naturally durable wood veneer with increased mechanical properties for use in structural composites. Half of...

  • Non-destructive evaluation of veneer using optical scanning and ultrasonic stress wave analysis systems

    Creator:
    DeVallance, David B.
    Abstract:
    Non-destructive commercial ultrasonic grading provides laminated veneer lumber (LVL) manufacturers a means for sorting veneer based on average ultrasonic propagation time (UPT) and/or average dynamic modulus of elasticity (MOEd). While this may provide reliable estimations of modulus of elasticity (MOE), little is known about the influence of veneer defects on...

  • Key factors influencing checking in maple veneered decorative hardwood plywood

    Creator:
    Burnard, Michael D.
    Abstract:
    Face checking in decorative maple veneered plywood panels is a significant problem for hardwood plywood manufacturers, furniture makers, cabinetmakers, and consumers. Efforts made by panel producers and researchers to minimize checking conducted to-­‐date have been limited, and produced contradictory results. In this study the impact of four manufacturing factors believed...

  • Influence of veneer roughness, lathe check, and annual ring characteristics on glue-bond performance of Douglas-fir plywood

    Creator:
    DeVallance, David B.
    Abstract:
    Current lathe technology, smaller diameter logs, smaller core diameters, and the sale of higher grade veneer for use in engineered wood products are all factors contributing to plywood manufacturers using rougher veneer with different lathe check characteristics. When rough veneer is encountered, plywood manufacturers typically increase the adhesive spread rate...

  • Life cycle inventory of laminated veneer lumber and composite I-joist manufacturing

    Creator:
    Dancer, Eric R.
    Abstract:
    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...
