“…In terms of chemical components, the content of alpha cellulose, hemicellulose, starch, and sugar decreased, the content of extraction and lignin increased, the pH value decreased, and the hydroxyl and hydrogen bonds of the cell surface decreased [31]. As for performance, the unit surface free energy and polarity decreased, the density, volume shrinkage, and equilibrium moisture content decreased, the hydrophobicity increased, and the elastic modulus of fibroblast and parenchyma cell wall remained unchanged, and the hardness increased significantly [32][33][34]. In the course of the above changes, the formation of cracks and the increase of grain size are conducive to the subsequent penetration of PF resin into the microstructure of bamboo.…”

At present, China is the world's largest producer of bamboo resource possessor and bamboo processing. The main processing method of bamboo recombination technology is rolling and compaction, by which a reconstituted material with bamboo fibrotic veneer as matrix and phenolic resin as reinforcement is prepared. It has excellent physical and mechanical properties and can replace high-quality wood to manufacture various engineering structural materials and building decoration materials. This paper reviewed the research process and progress of bamboo recombination technology, the existing technical problems and prospects, in order to provide references for future research on bamboo recombination theory and production practice. In recent years, as a new material with controllable properties, designable structures, and adjustable dimensions, bamboo reconstituted materials have been comprehensively studied from the aspects of pressing process parameters, physicochemical mechanical properties evaluation system, and microstructure characterization, but the research is not comprehensive and has not in-depth view. In the future, the relationship between microstructure and performance should be emphatically studied to clarify the law of mechanical performance change and ultimate mechanical performance under synergistic enhancement effect, as well as the performance change and interface formation of the resin during the entire molding process. Meanwhile, the reliability and relevance of applied research should be further expanded, and the integration of natural and artificial aging environment, process and performance, and macroand microscales should be strengthened.

In this study, a novel composite was fabricated based on phenol‐formaldehyde (PF) resin and bamboo fiber bundles. Various characterization techniques including fluorescence microscope, scanning electron microscopy coupled with energy‐dispersive X‐ray, and transmission electron microscope were used to investigate the distribution of fibers and infiltration of PF resin. The water repellency, dimensional stability, and decay resistance against both white‐rot (Trametes versicolor) and brown‐rot (Gloeophyllum trabeum) of the composites were also tested. The results showed that the resin not only deposited on the fibers surface, but also entered into the cellular wall and cell lumina through the pits. A great amount of resin was found in cracks and middle lamella of cell wall in resin impregnated bamboo fiber bundles owing to the mechanical defibering process. After thermal compressing, the bamboo cells were densified. The resin was redistributed in cell lumen and glue‐joints were formed. Some chemical reactions occurred between PF and bamboo by formation of aromatic esters and ether bonds, and the ether bonds were dominant. Thus, significant improvements in water repellency, dimensional stability, and biological resistance were achieved. These results suggested the composites can be used in exterior applications where high levels of water repellency and fungi resistance were required. POLYM.

“…The properties like rapid growth rate, short rotation age, excellent flexibility and high tensile strength has transformed bamboo into a wide variety of products ranging from domestic household products to industrial applications [21]. The uses in platforms (floors for transport vehicles such as trucks, busses and rail coaches), concrete molding boards (in building industries), flooring, furniture, pulp and handicraft works has provided new dimensions to bamboo utilization [22][23][24]. To elevate the utilization of bamboo, its fundamental physical and mechanical properties must be fully understood [25].…”

Bamboo has its own role in the development of society. It is widely used as a support tools for sustainable farming and being exceptional resource for variety of income and employment-generating systems. This overlooked biomass provides food, raw material, shelter, medicine for large part of world's population. Bamboo has given a great support to mankind by providing building materials that are extensively used for household products. It has found a good place for industrial applications due to advances in processing technology and increased market demand. Numerous fundamental studies were carried out to highlight their fundamental characteristics prior to industrial exploitation or high end bamboo-based biomaterials. The mechanical and physical properties of bamboo have noteworthy effects on their durability and strength. Thermogravimetry is one of the key sensitive technique that characterizes the mechanical responses of materials by monitoring property changes with respect to the temperature. Comprehensive review and study on thermal analysis are useful for quantitative determination of the degradation behaviour and the composition of the material. The magnitude and location of the derivative thermogravimetric curve also provides information of the interaction between the material components at various temperature scales. Therefore, these studies can be focused to evaluate the basic fundamental problems faced and thus, a well-designed research and development towards sustainability can be achieved.
