摘要：The interrelationship and organization between the axial and transversal systems gives rise to three main views, namely cross, radial and tangential sections. This study investigated the differences in combustion properties of the three main anatomical sections of poplar wood and explains the reasons for the differences regarding wood microstructure, pore structure, heat conduction, and microstructure after heat treatment. The thermal conductivity of poplar wood in the cross-section (Wood-CS) was 0.1864 W/m. K, exceeding those of the radial (Wood-RS) and tangential sections (Wood-TS) by 47% and 38%, respectively. In the cone calorimeter test (CC), the peak heat-release rate (pHRR) of Wood-CS samples was 92% and 73% higher than those of the Wood-RS and Wood-TS samples, respectively. This is attributed to the differences in microstructures and the occurrence of macropores in different anatomical sections. This study explored the combustion performance and mechanisms of wood samples in the three main sections, providing crucial theoretical insights for flame retardant impregnation levels in treating wood and aiding in the selection of fire-resistant wood-based building materials.
