Effects of molecular weight on mechanical properties of polypropylene/glass fiber injection moldings

摘要

In order to clarity the effect of molecular weight on mechanical properties and recyclability of polypropylene, the tensile properties of three types of polypropylene which have different molecular weights were investigated The increments of tensile properties by filling glass fiber were affected by the molecular weight As the conditions of interface were also affected by molecular weight, this caused the increments of mechanical properties.
