High performance fibers are widely applied to wood-based composites as reinforcement to improve mechanical performance of composites. Design and mechanical performance tests of basalt fiber cloth reinforced bamboo and poplar veneer (BFRBV) composite are presented in this paper. The fiber surface usually needs to be treated to increase the bonding strength of composites. The optimization scheme of maleic anhydride (MAH) treatment parameters was obtained by orthogonal experiment, namely temperature of 50 °C, time of 3 h and concentration of 0.08 mol/L. The mechanical performance of wood composites treated with three methods of fiber surface treatment, namely no treatment, KH550 treatment and KH550 and MAH co-treatment, was tested. The results indicated that the mechanical performance indexes of BFRBV composite were greatly improved with KH550 and MAH co-treatment. In comparison with no treatment, dry shear strength was improved by 113.3%, wet shear strength by 126.2%, peel rate was reduced from 20.15% to 0, and MOR was improved by 35.4%.
