The work aimed at the improvement of the mechanical properties of bamboo fiber-polypropylene composites (BaFPPC) by treatment of the fibers with CaCO3 at various concentrations of the solution (0.05, 0.1, 0.2, and 0.3 mol l(-1)). CaCO3 particles were successfully deposited in situ to bamboo fibers by means of ionic reaction of Na2CO3 and CaCl2 aqueous solution at various temperatures. Then BaFPPC were produced, and various tests on single fibers and the composites were performed. The compatibility between BaF and PP matrix was improved by the treatments. The crystallinity of inorganic materials was significantly affected by the reagent’s concentration. A 10.4% increase in tensile strength and a 16.7% increase in tensile modulus were observed after fiber treatment with CaCO3 at a concentration of 0.2 mol l(-1).
