Polypropylene composites reinforced by the ramier fiber and K2Ti6O13 whisker were successfully prepared by means of the torque rheometer blending and transfer molding. Their mechanical properties were tested, and the fracture surface of the composite was analysed by SEM technique. Results showed that the mechanical properties were improved by the addition of 10% of K2Ti6O13 whisker besides the impact strength. The RF is benefit for improving the mechanical properties of PP after being surface-treated properly.
