Basalt fiber-reinforced polypropylene composites have been widely used in industrial production for lightweight designs owing to their low price, good mechanical properties and environmental friendliness. In this study, the automotive door interior trimming panel composed of basalt fiber (BF) reinforced polypropylene (PP) was prepared by injection molding. The effects of BF on the stiffness of PP automotive door interior trimming panels were studied by experiment and simulation. The indentation test was carried out by digital image correlation (DIC) technology. The finite element simulation (FES) was conducted and the result was compared with that of experiment to verify the accuracy of the FES. Then, the stiffness test and the FES of the automotive door interior trimming panels were implemented to study the effect of basalt fiber on the stiffness of polypropylene. Furthermore, the thickness of the automotive door interior trimming panel was optimized by stiffness simulation. The results showed that the indentation test had a great agreement with the FES results. The addition of BF could effectively improve the stiffness of polypropylene plastic automotive interior panel. The BF-reinforced polypropylene plastic automotive door interior trimming panel with a thickness of 1.0 mm had the same stiffness with polypropylene plastic automotive door interior trimming panel with a thickness of 2.4 mm.
