Structural composite lumber (SCL), which includes laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL), is a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture resistant adhesive into blocks of material known as billets, which are subsequently resawn into specified sizes.
As composites are used in more applications and capture additional market shares, the need to better understand the material’s properties as they relate to secondary machining becomes more important. This study was conducted to ob-tain ﬁrst indications of secondary processing properties of ﬂat-pressed WPC panels made by a dry-blending method.
transfer through the pressed wood layers could be achieved by reducing the thickness of the pressed materials. In this sense, the aim of this research was to evaluate time gain as well as physical-mechanical properties of multilayered wood composites that were produced by adding successive layers (veneers) with different pressing times.

Particleboard, also known as chipboard, is an engineered wood product manufactured from wood chips, sawmill shavings, or even sawdust, and MDI, which is pressed and extruded. Particle board is denser and more uniform than conventional wood and plywood and is substituted for them when strength and appearance is more important.

When designing a commercial composite, the effect of particle size is one of the most important parameters affecting overall products properties. The use of optimum
This study aimed to enhance the dimensional stability of flat-pressed wood plastic composites (WPCs) containing fast growing wood fibres by a thermal-treatment method. The wood fibres were treated at three different temperatures (120, 150, or 180 °C) for 20 or 40 min in a laboratory autoclave.
Benthien et al. have recently investigated effects of formulation variables on the physical and mechanical properties of the flat pressed WPCs. However, currently there is little information about surface properties of flat-pressed WPC panels , , . The wettability and surface roughness are the most important factors affecting coating performance of the WPCs.
This study deals with the fabrication of composite matrix from saw dust (SD) and recycled polyethylene terephthalate (PET) at different ratio (w/w) by flat-pressed method. The wood plastic composites (WPCs) were made with a thickness of 6 mm after mixing the saw dust and PET in a rotary type blender followed by flat press process.
This study investigated physical, mechanical, and fire properties of the flat-pressed wood plastic composites (WPCs) incorporated with various fire retardants (FRs) [5 or 15% by weight (wt)] at 50 wt % of the wood flour (WF).
Physical and mechanical properties of the flat-pressed WPCs made by using a dry-blending method have not been widely studied. For this purpose, physical and mechanical properties of the WPC panels made from various mixtures of the wood fiber and PP powder were investigated, using a method currently used in the wood-based panel indus-try.
The effects of different kinds of coating materials on the properties of fl at pressed wood plastic composite (WPC) panels were studied in this work. Rotary-cut birch veneer, sliced oak veneer, phenolic impregnated paper, polyethylene (PE) fi lm, and recycled polyethylene (rPE) layer were used as coating materials.
Mechanical and physical properties of the panels manufactured from combination of plastic and wood material and fiber with addition of various types of chemicals are shown in Table 3. Average MOE value of the samples containing 60% and 80% wood fiber without having any chemicals was found 2109 MPa ( Fig. 6 ).
