摘要：
The objective of this study was to investigate the effects of functional wood modifier (urea-formaldehyde prepolymer) on fast-growing wood. The physical and mechanical properties and mainly chemical components were tested. Thermo-gravimetric analysis resulted in thermal stability improvement of the modified composites. The durability against fungus was examined and weight loss reached 6.16 % after modification. The FTIR spectroscopy showed the chemical changes in wood after modification and illustrated the modified mechanism. Finally, SEM and EDXA micrographs presented the distribution of wood modifier in cell wall.
