Modification of Wood Fiber with Thermoplastics by Reactive Steam-Explosion
… time, a novel processing method of co-refining wood and polyolefin (PO) by steam-explosion was scientifically explored for wood-thermoplastic composites without a coupling agent. Traditional studies have addressed the improvement of adhesion between components of wood thermoplastic composites …

Flexural behavior of a glass fiber reinforced wood fiber composite
The static and dynamic flexural properties of a wood fiber matrix internally reinforced with continuous glass fibers were investigated. When modelled as a sandwich composite, the static flexural modulus of elasticity (MOE) of glass fiber reinforced hardboard could be successfully predicted from the …

Improving efficiency in logistics operations of the wood fiber supply chain
… regarding applications of Lean tools in the wood fiber supply chain. A Value Stream Map (VSM) tool that focused on identifying Lean waste in logistic operations was developed and applied to three case study firms: a paper mill, a sawmill, and a logger. Using the VSM tool an absence of …

Wetlaid Cellulose Fiber-Thermoplastic Hybrid Composites - Effects of Lyocell and Steam Exploded Wood Fiber Blends
Fiber hybridization involves the blending of high and low performance fibers in a common matrix to yield a composite with a balance of properties that cannot be achieved by using either fiber alone. In this study, the random wetlay process was used as a compounding method to investigate the effects …

Bedding as a Factor in the Survival and Total Height of Two Year Old Planted Loblolly Pine Seedlings in East Texas
<p>With an ever increasing demand placed on wood fiber supply by industry, it has become imperative that every feasible means be pursued which will increase the wood fiber production per acre of land on every plantsble site. With this in mind, this study was conducted in an attempt to determine the …

Performance and environmental impacts of biocontainers in horticultural crop production systems
… tested. Other containers, such as peat, wood fiber, and manure had greatly reduced container strengths – especially when wet. These differences translated into greater damage rates during filling, handling, and shipping experiments. Plantable biocontainers (as compared to compostable) are …

Wood as an energy source in the Kraft pulp-paper industry of the southeastern United States
… a study in the economics of deriving energy from wood. Its objective is to provide guides to industry managers that will enable them to better assess wood's fuel potential. It is written with this business audience in mind. An introductory section describes the "energy crisis" as nothing more than …

Economic Feasibility of Implementing a Resin Distribution Measurement System for MDF Fiber
… phenol-formaldehyde adhesive on several types of wood surfaces. However, a technique that quantitatively measures UF resin on wood surfaces has been a problem because UF resin is colorless on wood fiber. The first objective of this study was to develop a technique to quantitatively measure surface …

An automatic method for inspecting plywood shear samples
Plywood is composed of several thin layers of wood bonded together by glue. The adhesive integrity of the glue formulation employed must surpass the structural integrity of the wood species within a given panel of plywood. The American Plywood Association (APA) regularly tests the plywood produced …
