Characteristics and Applications of Bamboo Fiber Materials

Sameen Ruqia Imadi, et al. Biomass and bioenergy: processing and properties, 2014, 27-46.

Bamboo fiber is a promising green fiber, thanks to its antibacterial, antifungal, antibacterial, hypoallergenic, hygroscopic, natural deodorant and UV resistance. Based on its multifunctional properties, bamboo fiber is widely used in the following fields:
· Biofuel production: Bioenergy products derived from bamboo fiber include charcoal, biofuel, pyrolysis, firewood, gasification, briquettes, pellets and biomass. Bamboo hemicellulose fiber with a hemicellulose content of 2.4% has been extracted and pulped. The pulp product can be used to produce biofuel and bioethanol after further modification.
· Building materials: Due to its high specific strength, tensile strength, tensile modulus, hardness and other mechanical properties, bamboo fiber can be used as a substitute for steel bars in concrete.
· Papermaking industry: Pulping properties and pulp strength make bamboo fiber one of the most suitable materials for papermaking. Bamboo pulp produced from hemicellulose fibers can be effectively used in papermaking. In the paper industry, bamboo fiber pulp can be used to form newsprint, coated paper, toilet paper, cardboard, cement bags and coffee filter paper.
· Medical industry: Bamboo fiber has excellent properties of inhibiting bacterial growth, absorbing odors, and hygroscopicity. Due to these properties, bamboo fiber is used as non-woven medical and sanitary materials.
· Textile industry: Studies on bamboo fiber have shown that its chemical composition is the same as that of all bast fibers, that is, it is mainly cellulose content and has less lignin content. Bamboo fiber has excellent spinning and weaving properties and can be used in the manufacturing industry of various types of fabrics.

High-Performance Bamboo-Steel Super-Strong Composites Based on Bamboo Fiber Reinforcement

Wang, You-Yong, et al. ACS applied materials & interfaces, 2020, 13(1), 1431-1440.

This work developed a bamboo-steel super-strong composite material by removing lignin and hemicellulose from bamboo and then impregnating the bamboo with epoxy resin under high pressure. Studies have shown that the integrity of bamboo fibers is preserved, high-pressure densification can increase the volume fraction of bamboo fibers, and the hydrogen bonding between adjacent bamboo fibers is enhanced. The impregnated epoxy resin enhances stress transfer due to chemical cross-linking with cellulose molecules, giving bamboo steel excellent mechanical properties.
Preparation procedure of bamboo steel
· Bamboo samples were soaked in a boiling solution containing 2.5 M NaOH and 0.4 M Na2SO3 for 12 hours, then washed with deionized water to remove any remaining chemicals. Following this, the bamboo samples underwent a bleaching process with 2.5 M H2O2 for 3 hours and were washed again with deionized water. The resulting porous bamboo scaffolds were achieved through freeze-drying the delignified and bleached bamboo.
· These bamboo scaffolds were then soaked in a liquid epoxy mixture and degassed under vacuum for 10 minutes. The epoxy mixture was made by dissolving the curing agent DDM in epoxy resin 711 at 60 °C, with a weight ratio of epoxy resin to curing agent of 100:31.
· Finally, the bamboo/epoxy composites were created by hot-pressing the bamboo scaffolds saturated with epoxy resin at 120 °C and 25 MPa for 8 hours. This process led to the densification of the bamboo scaffolds and the solidification of the epoxy resin.
