Abstract

The aim of this study was to describe a chemical modification on fast-growing woods. After modification, it was found that the bending strength increased 42.7%, the compressive strength parallel to grain increased 37.8%. Moreover, the characteristics of the unmodified and modified samples were studied by X-Ray Diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). The XRD analysis showed the degree of crystallinity changed from 35.49% to 37.31%, and the FTIR results revealed clear changes in the molecular structure. Finally, the SEM micrographs of modified and unmodified samples demonstrated strong and firm bonding between the inner wood cell and the wood modifier.
