A Study of Polypropylene Copolymer Nanocomposites With High Rigidity and High Impact Strength
Published October 12, 2011 by Society of Automotive Engineers of Japan in Japan
The influence of polypropylene/elastomer/fillers ternary composites on mechanical and impact properties were studied quantitatively and a method for predicting the properties of composites from their compositions was also developed. Using this method, the composition optimization in polypropylene-based nanocomposites consisted of well-dispersed two kinds of fillers and elastomers was conducted. The fabricated composites achieved excellent impact strength even at a relatively low amount of elastomers, as well as high flexural modulus and other fine properties. This result means that newly developed composites are especially suitable to bumper fascia materials.
