The wollastonite with fibrous structure can be used as the filler in the composite. In this paper, the composite was prepared by incorporating the wollastonite into butadiene styrene rubber (SBR) matrix through the mechanical agitation and roll mixing technologies. Mechanical properties of SBR filled with different amount of wollastonite content were studied and compared. It was shown that the mechanical properties of SBR filled with wollastonite could be improved significantly. The tensile strength and elongation at break were increased with the increase of the wollastonite. The tensile strength could be enhanced from 4.1MPa to 5.0MPa, and the elongation at break from 389% to 572%.
