11.1 – Elegant and strong natural timber requires periodic maintenance to maintain its durability. As an alternative to natural wood, composite fibre plastic material offers a practical middle ground and can be used to replace timber in some applications.
Composite materials (resin and fibers) are placed in an open mold, where they cure or harden while exposed to the air. Tooling cost for open molds is often inexpensive, making it possible to use this technique for prototype and short production runs.

The possibility of producing wood-plastic panels using a melt blend/hot press method was studied in this research.
The perpendicular orientation of the wood strands imparts strength properties to the panels. OSB panels measure 4’x8’ with thickness typically ¼” to 23/32”. OSB is widely used in residential construction for sheathing and flooring, as the web material for wood I-joists, and in the production of structural insulated panels (SIPs).

Materials and Methods -Rice Panels were made with one of three different resin combination methods. The
Composite panels are factory engineered panels used mainly for exterior cladding, partitioning, load bearing walls and roofing elements in a wide range of non-residential buildings. Panels are manufactured on a continuous lamination basis with metal facings - usually steel or aluminium - encapsulating a foamed polyurethane core.

Elements used in the production of wood-based composites can be made in a variety of sizes and shapes. Typical elements in- clude fibers, particles, flakes, veneers, laminates, or lumber. Figure 11–2 shows the variation and relative size of wood elements.
was discovered as a suitable material that shared the same or closely similar physical characteristics, mechanical properties and workability as timber hard wood. The composite fibre plastic material is made from a combination of organic fibre (e.g. rice husk or other similar materials) and post-consumer recycled plastics, which have
• Composite wood products used inside a new vehicle othe r than a recreational vehicle, such as rail cars, boats, and aircraft. • Windows that contain composite wood products if the windows contain less than 5% composite wood product by volume. • Exterior doors and garage doors that contain composite wood products, if the doors are made
water soak method (American Society for Testing and Materials 1994) is usually taken as the primary measure of the dimensional sta- bility of wood composite panel materials. Cy- clic relative humidity tests are also used to evaluate TS of many interior-use panel ma- terials; the water soak method accelerates TS
