Abstract: Silicon sol solution was introduced into poplar wood by vacuum-pressure impregnation process, and a series of composites with different weight percent of gain (WPG) were prepared. The structure and properties of the untreated and composite wood were investigated. Compared to untreated wood, composite wood had a promising potential to improve mechanical properties like bending strength, modulus of elasticity and surface hardness. SEM pictures of composite wood with 30.3 WPG showed that the SiO₂ gels filled the pores of the wood but unchanged the structure and morphological arrangement. TG and contact angle results indicated that composite wood showed an improved thermal property and water repellent property, and those properties increased with increasing of WPG.

Abstract: Considering the status of wood utilization in rapidly depleting forests, the various innovations introduced to meet the challenges of short supply, and to overcome some of the main defects of various species of wood are explained, particularly with reference to tropical countries like India. The associated developments in wood adhesives and wood joints are also briefly discussed. Some recommendations are suggested for new approaches
