Characterization of injection molded high density polyethylene/rice straw biocomposite

摘要

Polymer composite have been subjected to increasing interest, study, and utilization for some uddecades. The increase in environmental concern rationalize the use of reduce polymeric udmaterials, not only due to their non-biodegradabudility, but also due to their production requires udlarge amounts of oil as raw material which is notorudiously not renewable. All these issues induced udto look for alternatives. Thus, the interest arisudes toward polymer composites filled with natural udorganic fillers. Composite materials (or composites for short) are engineered materials made udfrom two or more constituent materials with udsignificantly different physical or chemical udproperties and which remain separaudte and distinct on a macroscopic level within the finished udstructure. Composite materials made from planudt fibers are receiving a great deal of today udattention since they are consideruded an environmentally friendly recourse. Among all reinforcing udfibers, natural fibers have gained their importaudnce especially for load bearing applications. udNatural fiber reinforced polymer composites arude superior over syntheudtic fiber reinforced udcomposites in certain properties like enhanced udbiodegradability, combustibudility, lightweight, ease udof recyclability, etc.ud These advantages place the naudtural fibers composites among high udperformance composites having economical and udenvironmental advantages, with good physical udproperties [1].
