Method The curing characteristics of powdery epoxy resin adhesive and bonding strength, flexure strength, thermal conductivity as well as hot-water resistance were investigated by differential scanning calorimetry (DSC), mechanical property test and thermal conductivity tester. Result (1) The optimal curing condition of powdery epoxy resin adhesive was that the curing reaction began at 84 ℃, curing thoroughly at 116 ℃, and curing completely at 180 ℃. (2) When the amount of glue was 150 g·m−2 and the hot pressing time was 15 min, the tensile bonding strength and flexure strength of the composite reached 0.83 MPa and 19.8 MPa respectively, and the thermal conductivity was 0.054 2 W·m−1·K−1 (25 ℃). After being soaked in hot water at 80 ℃ for 3 h, the bonding strength of the composite still reached 0.15 MPa. Conclusion The bamboo scrimber/structural insulated panel composite with excellent comprehensive properties and good hot-water resistance is obtained. [Ch, 6 fig. 2 tab. 21 ref.] -
