figure 11 shows sem micrographs of the dynamic compression fracture at a dynamic loading of 1100 s-1 in sawdust/hdpe composites with different sawdust particle sizes. fig. 11. the fracture surface of sawdust/hdpe composites with various particle sizes of (a) 500 µm, (b) 250 µm, (c) 125 µm, and (d) 63 µm under 1100 s-1 of strain rate

influence of modifiers on the physicomechanical properties of ...

polymer-wood composites based on recycled polyethylene (rpe) are investigated. dispersed alder sawdust was utilized as a filler. to improve the compatibility between the nonpolar matrix and the polar wood fibers as a reinforcement, two types of modifiers were used, which differed in their chemical nature and mechanical interaction with the constituents of the composites.

treated tropical wood sawdust-polypropylene polymer composite ...

wood particles and poor reinforcement between sawdust and polymer. the sawdust is polar and polymer non po-lar has leads to incompatibility problem between the ma-terials. hence affect the mechanical and physical proper-ties of the composites [8]. interfacial interactions are very weak in sawdust fiber filled composites, because the

a review of wood plastic composites effect on the ...

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.

the curing characteristics and mechanical properties of wood ...

that the tensile strength and elongation at break of the composites decrease with wood sawdust loading. the decrease in tensile strength and elongation at break of the composites by the addition of wood sawdust were attributed to the increase in interfacial defects between epdm and wood sawdust phases due to the use of sawdust particles.

effect of moisture absorption on mechanical properties of ...

research in the field of green technology is being done to provide wood substitutes which makes use of wood materials mixed with polymer to provide a cost-effective, improved performance and termite resistant wood polymer composites. wood polymer composites (wpcs) are made by mixing wood saw dust with polymer matrix material, polypropylene in ...

selection of teak sawdust polypropylene composite’s ...

selection of a material for their end use in engineering applications depends on the properties of materials. in this paper, physical and mechanical properties of teak sawdust-polypropylene composite are evaluated and most suitable composition for outdoor applications have been determined by using topsis technique of optimization.

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

prospects for growth in wood plastic composite markets

typically, wpcs combine saw dust or wood-flour with a variety of plastic polymer types and other fillers. the composites offer better mechanical properties than traditional products, such as rigidity and strength compared to other plastic materials, and improved weather resistance and lower maintenance needs compared to traditional lumber.

composites from thermoplastic natural rubber reinforced ...

because these composites have high stiffness wood sawdust and low stiffness polymer matrix, the increasing addition of wood filler volume into the composites increases the stiffness . jamil et al. [ 2 ] revealed that an increment of modulus causes a decrease in the flexibility or elasticity of the soft matrix.
