“…The better interfacial interaction increased the tensile properties of the composite filaments manufactured by the “one-step” method, which was confirmed by the tensile testing results. In addition, according to the research [39,40], the tensile properties were related not only to the interfacial compatibility but also to the raw materials themselves. For nano-particles reinforced composites manufactured by the “two-step” method, the effect of raw materials on tensile strength was more than the interfacial compatibility between reinforcement and matrix.…”

The focus of this report was to understand the tensile properties and dynamic mechanical properties of bamboo powder (BP) reinforced polylactic acid (PLA) composite filaments which were treated with nano calcium carbonate (CaCO3), cellulose nanofibers (CNF), and micro-crystalline cellulose (MCC) using impregnation modification technology. The storage modulus (E’) of nano CaCO3-BP/PLA, MCC-BP/PLA, and CNF-BP/PLA composite filaments increased compared with BP/PLA composite filaments before the glass transition temperature Tg. When the temperature was above Tg, the reinforcement effect of nano CaCO3, MCC, and CNF gradually became less apparent. The loss modulus (E’’) and loss factor (tan δmax) of the nano CaCO3-BP/PLA, MCC-BP/PLA, and CNF-BP/PLA composite filaments was higher than that of BP/PLA composite filaments produced by the “one-step” method. The tensile strength (TS) results showed a similar trend. Compared with the control samples, the TS of nano CaCO3-BP/PLA, MCC-BP/PLA, and CNF-BP/PLA composite filaments produced by the “one-step” method (and the “two-step” method) increased by 40.33% (and 10.10%), 32.35% (and −8.61%), and 12.32% (and −12.85%), respectively. The TS of nano CaCO3-BP/PLA, MCC-BP/PLA, and CNF-BP/PLA composite filaments produced by the “one-step” method was slightly higher than those produced by the “two-step” method. The elongation at break (EAB) of BP/PLA composite filaments was higher than that of BP/PLA samples treated with nano CaCO3, MCC, or CNF. The PLA and modified BP were readily accessible through a simple mixing process. The rheological investigation of such mixtures showed that nano CaCO3, CNF, and MCC have different effects on the processability and rheological properties of composites.

“…Most biomass-based self-bonding processes involve physical (Luo and Yang, 2011), chemical (Lamaming et al 2013), or biological pretreatment (Song et al 2018) of biomaterial residues to degrade cellulose, lignin, and hemicellulose and further induce selfbonding under hotpress (Nasir et al 2019). It is suggested that mechanism of self-bonding contributes to inter-fiber bonds (Dominguez-Robles et al 2020), based on Van der Waals forces and hydrogen bonding, as well as chemical reactions such as dehydration, hydrolysis and oxidation reaction, especially during hot pressing.…”

Self-bonding bamboo particleboards were prepared via hot pressing of bamboo residue fermented by lactic acid bacteria. An orthogonal experiment was designed to investigate the effects of three factors (type of lactic acid bacteria used for fermentation, moisture content (MC) of the fermented residue, and hot-pressing temperature) on the resulting self-bonding particleboards. The bending strength and internal bonding strength of the prepared self-bonding particleboards were tested. Fracture characterization was performed on the cross-section of the prepared self-bonding particleboards after bending breakage. The hot-pressing temperature, moisture content (MC), and type of lactic acid bacteria of the fermented residue had a significant effect on the mechanical strength of self-bonding particleboards, and with increased hot-pressing temperature, the strength of self-bonding particleboards increased. Analysis of the cross-sectional morphology and porosity confirmed the significant effect of hot-pressing temperature on the density distribution of self-bonding particleboards. The self-bonding particleboard produced at the hot-pressing temperature of 180 °C, MC of 30%, and that used Lactobacillus plantarum as a fermentation strain showed the best overall performance and reached Chinese standard requirements for common particleboards.

“…It has exceptional mechanical qualities, low reproductive di culty, and ease of transformation. As a result, bamboo represents a sustainable solution to the increasing demand for wood, and its use can lessen the negative effects on the environment brought on by the overuse of wood resources [2][3][4][5].…”

The impact of combined oil and thermal modification on the properties of bamboo was explored through macroscopic tests, but the internal mechanism remaine4d challenging to comprehend. To gain further insights, this research employed molecular dynamics simulation to estimate the mechanical properties, diffusion coefficient, cohesive energy density, and chain flexibility of bamboo fibers following oil heat treatment. A model of oil-cellulose composite was established and simulated at varying temperatures. Results showed that oil heat treatment led to higher mechanical strength and modulus of elasticity in bamboo fibers compared to untreated ones. Additionally, the increase in diffusion coefficient and cohesive energy density, as well as the optimization of cellulose chain flexibility, indicated an improvement in the fiber characteristics. Of note, the most significant enhancement in the mechanical properties of cellulose and the utilization rate of bamboo was observed after oil heat treatment at 180℃.
