“…The resin-coated strips were then oven-dried to an MC of 10–12%. The resinated, dried strips were hand-laid into a mold with side pressure baffles with the inner face of the strips facing the core and the outer faces facing the surfaces for uniform symmetry in the vertical direction [ 32 ]. To adjust density, between 6 and 8 strips were used per panel, which resembled unidirectional LVL in configuration.…”

Controlling the variability in mat structure and properties in bamboo scrimber (BS) is key to producing the product for structural applications, and wide strip scrimber (WBS) is an effective approach. In this study, the effects of scrimmed bamboo bundle morphology and product density on the properties of WBS were investigated. WBS panels were manufactured and tested using wide (200 to 250 mm) bamboo strips with different fiberization intensity. Maximum strength properties (flexural, compressive, and shear strength), and lowest thickness swelling and water absorption were achieved with three or four passes due to the higher resin absorption by strips. For balanced product cost and performance, we recommend 1–2 fiberization passes and a panel density of 0.9–1.0 g/cm3. Panel mechanical properties were compared with other common bamboo composites. Bamboo scrimber products were highly variable in properties due to differing manufacturing processes, element treatments, and suboptimal mat structure. Products including laminated bamboo lumber and flattened bamboo made from nonfiberized elements show markedly different relationships between strength and elastic properties mostly due to inadequate bonding between the laminae, which causes premature bond-line failure. This study helped improve the understanding of the structure–property relationship of engineered bamboo products while providing insights into process optimization.

“…Compared with other natural fibers, BF has the advantages of fast growth and low cost. In addition, excellent mechanical properties and natural antibacterial properties of BF have made it widely used in medicine, textile, building materials and other fields [3][4][5][6][7][8] . Generally， BF is composed of cellulose, hemicellulose and lignin, and the highest content in BF is cellulose [9][10][11][12] .…”

Inspired by wet-cool/dry-hot cycle drived prebiotic reactions, a green and efficient dry-wet cycle modification method was proposed for the preparation of polypeptide-modified bamboo fiber (P-MBF). Functionalization of P-MBF was characterized by Fourier transform infrared spectroscopy, X-ray diffraction, element analysis and scanning electron microscopy. Compared to raw bamboo fiber materials, P-MBF showed better dispersibility in aqueous solutions, and thus exhibited better adsorption performance for glycopeptide antibiotics in sewage treatment. With vancomycin as the target antibiotic, adsorption performance of P-MBF was studied in aqueous solution. Adsorption kinetics and isotherms were well correlated with pseudo-second-order model and Langmuir model, respectively. Investigation of thermodynamic parameters implied that the adsorption was a spontaneous exothermic process. The adsorption efficiencies in standard solution and drinking water were 97.83% and 91.32% , respectively. This study provides a green, efficient and economical modified bamboo fiber material for the removal of glycopeptide antibiotics from sewage samples.

“…Researchers have developed their attention in the invention of stronger raw materials, such as bamboo fiber, that can be used to produce high‐quality industrial products. [ 9 ] Moreover the twill weaving design ensures high endurance and strength to the entire mat and composite. On compare than plain weaving the twill weaving consumes more fiber yarns indicating higher strength and long life.…”

This research aimed to find the effect of Artocarpus heterophyllus fruit seed husk biochar (ASB) and twill weaved bamboo fiber (TBF) in mechanical, DMA, and fracture toughness behavior of epoxy-based composite. The surface of both weaved bamboo fiber and biochar was treated with amino silane before composite making. In this investigation, the laminates were fabricated by hand layup process and analyzed by appropriate ASTM standards. Results of this study revealed that the incorporation of 40 vol.% twill weaved bamboo fiber (EB) into the resin improved the mechanical properties. The load distribution was uniform with twilled weaving. For composite designation EBJ3, the maximum measured tensile strength was 168 MPa, the tensile modulus is 6.24 GPa, the flexural strength is 195 MPa, and the flexural modulus is 6.85 GPa, the izod impact is 6.24 J, and the hardness is 90 shore-D. Similarly, the maximum storage modulus and lowest loss factor for the composite designation EBJ3 were measured to be 3.8 GPa and 0.4, respectively. Moreover, the maximum measured fracture toughness and energy release rate is 39.4 MPa.√m and 0.88 MJ/m2 for composite designation EBJ3 with 5.0% biochar and 40% bamboo fibers in volume. The SEM fractography revealed that the matrix molecules are adhered to the fiber, indicating enhanced bonding. These biomass waste converted fruit seed husk biochar and industrial crop bamboo fiber epoxy composites could be used as workable material in structural, defense, automotive, and domestic product-making applications.
