Abstract The surface modification of basalt fiber (BF) using a sodium carboxymethyl cellulose (CMC) solution was investigated, focusing on the impact of different CMC solution concentrations and BF orientation on the performance of BF/ethylene propylene diene monomer (EPDM) composites. The results demonstrated that as the CMC solution concentration increased, the elongation at break, tear strength, and tensile strength of the BF/EPDM composites initially increased and then decreased. The energy storage modulus and loss factor (tanδ) of the compo-sites first decreased and then increased. Notably, when the CMC solution concentration reached 0.5wt%, the composite material exhibited optimal overall performance. Compared to the blank specimen, its tear strength, tensile strength, and DIN abrasion resistance increased by 2.7%, 10.9%, and 4.8%, respectively. Furthermore, when a CMC solution concentration of 0.5% (mass fraction), the energy storage modulus of the composite material after BF radial orientation is the lowest amongst the three types of orientation, while its tensile strength, tear strength, and DIN abrasion resistance were improved by 4.8%, 4.2%, and 3.8%, respectively, compared with the mixed orientation. SEM analysis revealed that the BF treated with 0.5wt% CMC solution was uniformly and completely coated with CMC.
