OS1706 Effect of calcium carbonate particle dispersion on the mechanical properties of PP/aramid fiber composite
Details
Polypropylene (PP)/aramid fiber (AF) and PP/AF/calcium carbonate (CaCO_3) composites were fabricated by melt-mixing process using a single screw extruder. Dumbbell shaped specimens were also fabricated from these mixture by injection molding process. Tensile and three-point bending tests were conducted using these specimens, and obtained results were compared for discussion of effect of CaCO_3 particle dispersion on the mechanical properties of PP/AF composite. Results show that tensile strength and modulus were improved by AF compounding. CaCO_3 particle dispersion effect was observed at tensile modulus of PP/AF/CaCO_3 with 0.15μm diameter.
