“…A maleated triblock copolymer styrene-ethylene/butylenestyrene (MASEBS) has also been shown to be an effective impact modifier when used in wood flour and polyolefin systems (Oksman 1996;Oksman and Lindberg 1998). Maleic anhydride is grafted to the ethylene and butylene chain to improve the physical and chemical properties of the polymer by providing polarity to promote hydrophilicity and improve adhesion and compatibility with other polymers and fillers.…”

High-density polyethylene (HDPE) and natural fiber composites were prepared by melt compounding and injection molding. The influence of fiber type (i.e., pine, bagasse, rice straw, and rice husk) and the addition of coupling agents on the composite properties were investigated. The use of 30 wt% fiber enhanced the tensile and flexural properties of neat HDPE, but decreased the impact strength. The comprehensive mechanical properties of HDPE/natural fiber composites were significantly improved by the addition of 2 wt% maleated polyethylene (MAPE). The toughness was further enhanced with the use of 5 wt% maleated triblock copolymer styrene-ethylene/butylene-styrene (MASEBS). The composites had higher crystallization peak temperatures and lower crystallinity levels than neat HDPE, and their thermal stability was lower than that of HDPE. The reduced storage modulus and increased loss tangent showed that MASEBS performed as a flexibilizer in composites.

“…For improving the bond between the matrix and the reinforcing material, coupling agents such as isocyanates and silanes Maldas et al 1989) or compatabilizers can be used because compatabilizers possess properties of both the matrix and the reinforcement in one molecule (Maldas et al 1988;Felix and Gatenholm 1991;Rowell et al 1997;Sanadi et al 1993;Simonsen et al 1997;Oksman and Clemons 1998;Oksman and Lindberg 1998).…”

Chemical modifications of Scots pine (Pinus sylvestris) wood flour were performed with vinyl acetate (VA) and acetic anhydride (AA) in the presence of potassium carbonate as a catalyst. Scots pine wood flour samples were successfully acetylated with VA (19 wt% gain) and AA (24 wt% gain). The effect of chemical modification of the Scots pine wood flour with AA and VA on the mechanical properties of wood high-density polyethylene composites (WPC) was determined. It was observed that acetylation of wood flour allowed a significant increase in both the mechanical properties and the thermal stability of the WPCs. It was concluded that acetylation of lignocellulosic fibers improves thermal stability, dispersion in the polymer matrix, and compatibility with the polymer matrix.

“…As a result, both polymer matrices and natural filler systems have been widely investigated [10]. As a matter of fact, Oksman and Lindberg [11] as well as the team of Liao et al [12] studied the mechanical behavior of composites based on polyethylene and wood flour samples. On the other hand, Zaini et al [13] and Kaci et al [14] investigated the mechanical behaviors of polypropylene/wood flour composites.…”

Polymer matrix composites, reinforced with various types of particles are being widely used to reduce the overall weight of structures because of their good combination of various properties such as high strength to weight ratio, good fatigue properties, corrosion resistance, etc. However, most of the polymeric materials are not bio-degradable. As a result, demands of natural fiber reinforced composites are increasing day by day. Considering this, initiative was taken to develop wood saw dust particles reinforced polymer (unsaturated polyester) matrix composites with varying proportions (5 and 10% by weight [w/w]) of various wood saw dust particles. The developed composites were characterized by means of Tensile Test, fractography of the broken tensile test samples and water absorption test. Experimental results exhibited that addition of wood particles decreases the tensile strength of the composites and that, for higher strength wood, the degradation of the tensile strength of the composites is minimized. Addition of wood particles increases the water absorption of the composites. Water absorption of both pure polyester and wood particle reinforced composites has been found to increase with increase in time. However, the overall water absorption behaviors of the composites are dependent on the density of the wood used.
