Abstract GF/PP composites were prepared using the one-step process of direct fiber feeding injection molding (DFFIM), and the effect of injection speed and plasticization temperature on the properties of composites fabricated by DFFIM was studied, and the advantages of DFFIM technology were experimentally compared with the “two-step” technology. The results show that when the injection speed increases from 5 mm/s to 45 mm/s, the mechanical properties of GF/PP composites show a trend of first increasing and then decreasing, and the maximum tensile, bending and unnotched impact strength are 95.0 MPa, 133.9 MPa and 61.7 kJ/m², respectively, at the injection speed is 15 mm/s. When the plasticizing temperature increases from 205 ℃ to 250 ℃, the mechanical properties of the composite gradually improve, and when the plasticizing temperature continues to increase to 265 ℃, the tensile and impact strength of the composite decrease significantly, while the bending strength decreases from 133.9 MPa at 250 ℃ to 132.9 MPa. Compared with the “two-step” technology, GF/PP composites fabricated by DFFIM have obvious fiber length advantages, but after the glass fiber content exceeds 30%, its mechanical properties are gradually lower than the composite fabricated by the “two-step” technology using L-GFPP pellets.
