The BF/EP composites were prepared by embossing with basalt fiber plain cloth (BF) added to epoxy resin (EP). The effects of different layers of basalt fiber cloth on the mechanical properties and fracture toughness of the composites were investigated. The experimental results show that the bending strength, impact strength and fracture toughness of BF/EP composites were significantly better than that of epoxy resin. Compared with the epoxy resin without BF, the bending strength of the composite increased by 2.76 times after adding three layers of BF. The notched impact strength increased by 19.67 times, the unnotched impact strength increased by 5.94 times, and the KIC increased by 2.97 times.
