The Effect of Water Absorption on Mechanical Properties of Wood

The main objectives of this research were to study the effect of water absorption on mechanical properties of hybrid fiber reinforcement for polypropylene composites. The poor resistance towards water absorption is one of the draw- backs of natural fibers. hybrid filler-polypropylene composites are subjected to water immersion tests in order to study the effects of water absorption on the mechanical properties. composites specimens containing 30 phr and 40 phr fiber weight were and nbsp;


Critical processing temperature in the manufacture of fine-celled

Abstract. The main benefits of incorporating wood fibers (WF) in plastics are the increased stiffness and lowered cost of the resulting composites. However, these improvements are usually accompanied by a reduction in the ductility and impact resistance. These shortcomings can be removed by effectively foaming and incorporating a fine-celled structure in these composites. The volatiles released from WF during processing are known to deteriorate the cell structure.

Wood particle characterization in Wood-Polymer- Composites (WPC

wood-Polymer composites (WPCs) are innovative hybrid materials and substitutes for many conventional product applications due to their 3-dimensional mouldability, durability and weather resistance. WPC can be formed by a thermoplastic process and consist of renewable materials (wood particles or natural fibres), mostly synthetic plastics, such as polypropylene, and additives. The manufacturing process is a decisive factor determining the specific material characteristics of WPC.
