PP/稲わら複合材料の内部構造と力学特性に及ぼすMAPPの影響

抄録

Although composites using cellulosic plant fibers as filler contribute to the realization of a low-carbon society, they have poor interfacial adhesion with non-polar polymers such as polypropylene (PP), resulting in decreased mechanical properties. Maleic anhydride-modified polypropylene (MAPP) as a compatibilizer was filled to PP/rice straw composites to improve interfacial adhesion. Observation of the fracture surface showed that the addition of MAPP improved the interfacial adhesion between rice straw and PP. As a result, the tensile strength was greatly improved by filling MAPP and was higher than pure PP.
