Abstract To enhance mechanical properties and improve flame retardancy and smoke suppression of fast-growing poplar
wood in wood applications, the wood was impregnated and modified. An organic phenolic prepolymer and inorganic sodium silicate was used as contrasting impregnation modifiers and wood samples were impregnated by a
bionic “respiration” method with alternating positive and negative pressure. The weight percentage gain, density
increase ratio, mechanical properties (bending and compressive strength and hardness), and water absorption rate
of inorganic and organic-impregnated modified poplar wood (IIMPW and OIMPW, respectively) were compared
and these properties in IIMPW were found to be… More >
