4. Conclusions
- i.
- A series of PP/FA/WSP composites were successfully prepared through the injection molding machine, even if the total mixing ratio of FA and WSP is as high as 50 wt%.
- ii.
- SEM, EDS, XRD and FTIR analysis results show that the distribution of FA and WSP in PP is uniform. There are no cracks, fractures or other defects on the surface of PP/FA/WSP composites.
- iii.
- TGA results show that the weight ratio of all PP/FA/WSP composites is similar to the predetermined value. It indicates that FA, WSP and PP are uniformly mixed and the injection molding method is suitable for preparing PP/FA/WSP composite materials.
- iv.
- For mechanical properties, although the addition of FA and WSP leads to a decrease in the tensile strength of PP/FA/WSP composites, the addition of appropriate amounts of FA and WSP leads to an increase in the bending strength and notched impact energy of PP/FA/WSP composites by 2.20–4.71% and 14.58–22.22%, respectively.
