  1. Flake Orientation Effects On Physical and Mechanical Properties of Sweetgum Flakeboard

    Research was initiated to determine the effect of flake orientation on the physical and mechanical properties offlakeboard. The panel fabrication techniques investigated were single-layer panels with random and oriented flake distribution, three-layer, five-layer, and seven-layer panels. Single-layer oriented panels had panel directional property ratios of 11.8 and 12....

  2. Lightweight panel study 2012: Perceptions and usage by North American wood products manufacturers

    Lightweight panels (panels made of two thin panels on the outside and a lightweight material in the core) can offer enhanced performance, reduced material use, and new design opportunities over traditional types of panels. Opportunities exist for the adoption of lightweight panels by the secondary wood industry in North America, as 62 percent of respondents to a recent...

  3. Consumer and manufacturer perceptions of hardwood panels made from character-marked lumber

    Hardwood panels made from edge-glued material are a versatile product that could be within the reach of many smaller wood products firms. However, products would need to be accepted throughout the supply chain for this opportunity to be achieved. This study evaluated preferences of consumers and manufacturers towards edge-glued panels from Alaskan red alder and paper...

  5. Technical feasibility of structual flakeboard made from mixed hardwoods and cypress from northern florida

    Homogeneous and 3-layer flakeboard panels were fabricated from mixed hardwood species and baldcypress grown in northern Florida. All panels yielded adequate bending strength and stiffness and dimensional stability. For the homogeneous panels, the study indicates that only one panel condition, i.e., 5.5 percent resin content (RC) and 45 pcf, yielded internal bond (IB)...

  6. The changing market for hardwood plywood stock panels.

    The major end product for hardwood plywood (usually birch) stock panels in 1970 was kitchen cabinets. About 1/3 of the volume was shipped to the Pacific region. Over 1/3 of the responses by wholesalers indicated that stock panel sales had declined over the preceding 3 years, chiefly because of the inroads being made by plastic covered particleboard panels. The...

  7. Volatile organic compound emissions during hot-pressing of southern pine particleboard : panel size effects and trade-off between press time and temperature

    In previous research, it was shown that decreasing either press temperature or press time generally resulted in decreased volatile organic compound (VOC) emissions during the hot-pressing of southern pine particleboard. However, because it is impossible to reduce both pressing time and temperature while maintaining panel physical and mechanical properties, this study...

  8. Exterior structural composite panels with southern pine veneer faces and cores of southern hardwood flakes

    One-half-inch-thick, 8tructural exterior composite panels of various constructions were made in a one-step process, with faces of eouthern pine veneer and corea of mixed southern hardwood flakes. The flakes were precisely machined to be 3/8-inch wide, 3 inches long and 0.015 inch thick. Two veneer, cross-laminated on each face over an oriented flake core, yielded the...

  9. Flakeboard properties as affected by flake cutting techniques

    Flakeboards were prepared from flakes obtained from disk, drum, and ring flakers, and a shaping-lathe headrig. Species used were lodgepole pine,loblolly pine, sweetgum, southern red oak, and mockernut hickory at 1.25 compression ratio and two resin contents (5% and 8%). The three-layer panels had 25 percent of the largest flakes on each surface; all other material...

  10. Modelling the drying of three-dimensional pulp moulded structures. Part II, Drying data obtained from flat panels using virgin and recycled paper fibre

    A three-dimensional structural panel, called FPL Spaceboard, was developed at the USDA Forest Products Laboratory. Spaceboard panels have been formed using a variety of fibrous materials using either a wet- or dry-forming process. Geometrically, the panel departs from the traditional two-dimensional flat panel by integrally forming an array of perpendicular ribs and...

  11. Edge-glued panels from Alaska hardwoods: retail manager perspectives

    In Alaska, red alder (Alnus rubra Bong.) and paper birch (Betula papyrifera Marsh.) are both lesser-known hardwoods grown, harvested, and manufactured into appearance products, with potential for increased utilization. The production of edgeglued panels from red alder and paper birch offers one expansion opportunity for wood...

  13. Improved fatigue performance for wood-based structural panels using slot and tab construction

    This paper presents static and fatigue bending behavior for a wood-based structural panel having a slot and tab (S/T) construction technique. Comparisons were made with similarly fabricated panels without the S/T construction technique. Experimental results showed that both types of panels had similar bending properties in the static tests. However, the panels with S/T...

  14. Evaluation of modulus of elasticity and modulus of rupture of full-size wood composite panels supported on two nodal-lines using a vibration technique

    The objective of this study was to determine the feasibility of using a transverse free vibration testing method to nondestructively evaluate the bending stiffness and strength of full-size (1220 x 2440 mm) wood composite panels (WCPs). Based on the principle of transverse free vibration of a thin plate, the dynamic modulus of elasticity (MOE) of a full-size WCP...

  15. Performance of structural insulated panel walls under seismic loading

    Structural insulated panels (SIPs) are a viable, energy-efficient, cost-effective option for commercial and residential buildings. But, acceptance of SIPs has been hindered by the lack of systematic evaluation of lateral load performance in wall applications. This study provides the data needed to characterize lateral load performance of several configurations of SIP...

  16. Issues related to panel creep

    The annual inventory system was designed under the assumption that a fixed percentage of plots would be measured annually in each State. The initial plan was to assign plots to panels to provide systematic coverage of a State. One panel would be measured each year to allow for annual updates of each State using simple estimation procedures. The reality is that...

    In this study, the effects of cellulose nanofibrils (CNFs) ratio, press program, particle size, and density on the vertical density profile (VDP) and internal bond (IB) strength of the wet-formed particleboard were investigated. Results revealed that the VDP was significantly influenced by the press program. Pressing using a constant pressure (CP) press program...

  20. Relative Performance of Lindgren Multiple-Funnel, Intercept Panel, and Colossus Pipe Traps in Catching Cerambycidae and Associated Species in the Southeastern United States

    In 2004, we evaluated the relative performance of 8-unit Lindgren multiple-funnel (funnel), Intercept panel (panel), and Colossus pipe (pipe) traps, baited with ethanol and α-pinene lures, in catching saproxylic beetles (Coleoptera) in pine stands in northern Florida and western South Carolina. Panel traps were as good as, if not better than, funnel and pipe...
