Mechanical Properties of Sisal Fiber Reinforced Thermoplastic Starch Bio-Composites

摘要

Natural fiber reinforced starch based composites are processed by compression molding technique. Corn starch is used as matrix. 65% w/w Sisal fiber were used in preparing the composites. Glycerol and water are used plasticizers. Mechanical properties like ultimate tensile strength and impact strength were found. In both cases, improved mechanical properties are obtained at increasing fiber contents. Tensile strength look noticeably improved with the addition of 10% by weight of sisal fibers, while the results for impact strength obtained for sisal fibers are fall apart.
