In this paper the impact toughness of the basalt fabric reinforced epoxy resin composites was discussed. In the test, the basalt fabricwas used to reinforce the TDE-86epoxy resin, and 70#anhydride was used as curing agent. The mode of [45°/-45°] was chosen to layering and prepare the unit-cells. Resin Transfer Molding instrument was used to cure and make the basalt fabricreinforced epoxy resin composites, and the instron-based Dynatup9250HV material impact testing machine was used to test the impact resistance. Conclusion: in the low-velocity impact test, the maximum load the sample can bear was about 9.6538kN,and the total energy the sample absorbed was 19.3030J; Observing the impact morphology of the sample, the basalt fabricreinforced epoxy resin composite was not perforated, then its failure mode was matrix cracking, drawing and fracture of the fiber. The results provided a scientific basis for basalt fabricreinforced composites, and increase the development of the production related to the basalt fabriccomposites.
