“…The FTIR spectra of bamboo powders and BSCs are shown in Figure 5a. The BSCs with a preset density of 1.0 g/cm 3 were fabricated from bamboo powders with 40% moisture content at a hot-pressing temperature of 200 °C. The acetyl groups in hemicellulose and the C�O stretching vibration were attributed to the absorption peak at about 1730 cm −1 .…”

“…Bamboo can be processed into bamboo culms, bamboo sticks, bamboo bundles, bamboo strips, bamboo fibers, and bamboo pulps to manufacture a wide arrange of bamboo-based products for use in construction, furniture, transportation, textile, packaging, paper, and so on (Figure ). Prior to being manufactured into furniture products, bamboo needs to be processed into bamboo laminated lumbers, bamboo scrimbers, bamboo particleboards, and bamboo fiberboards, which are usually subsequently bonded with urea-formaldehyde, phenol-formaldehyde, or melamine-urea-formaldehyde adhesives . However, the formaldehyde emissions from these adhesives pose a risk of environmental contamination and human health hazards .…”

Self-bonding technology is a facile and green molding approach to obtain eco-friendly and formaldehyde-free bamboo self-bonded composites (BSCs), yet the manufacture process is still immature. Here, the effects of processing parameters (moisture content of bamboo powders, hot-pressing temperature, and preset density) were comprehensively examined on the microstructure, physical properties, and mechanical properties of the BSCs for use in furniture. It was found that the optimum water resistance and mechanical properties were achieved for the BSCs made of bamboo powders of 40% moisture content. Higher temperature and preset density facilitated the formation of a more compact structure, leading to remarkable improvement in water resistance and mechanical performance. Given energy saving, the recommended processing parameters of the BSC manufacture were 40% moisture content of bamboo powders, 200 °C hot-pressing temperature, and 1.0 g/cm 3 preset density, yielding high-performance BSCs with a thickness swelling of 12.8% and internal bonding strength of 0.71 MPa, which were comparable to commercial furniture-grade medium-density fiberboards. The colorful patterns could be successfully printed by a UV inkjet printer on the BSC surface and exhibited good paint film adhesion, which holds great potential for application in furniture.

“…Bamboo laminated beams are made from layers of the material that have been shaved and glued together in the same direction of the grain to create substantial blocks (S. Chen et al, 2022;Kumar & Mandal, 2022;Mahdavi et al, 2011;Wang et al, 2021). The bamboo is sorted, grouped according to thickness, and then shaved in order to perform the bamboo lamination process.…”

Petung bamboo is one of the alternatives to wood that is needed due to the decreased availability of wood in the forest for construction. The objective of this research was to determine whether Petung bamboo could substitute wood in door frame. Research has been carried out to propose alternate methods of using bamboo to produce door frame that are environmentally friendly. Engineering research using experimental methods is conducted. The data collection technique was carried out using test specimens for specific gravity test, compressive strength test, and flexural strength test to obtain the strength value of the petung bamboo laminated door frame product which will later be compared with door frames made of wood on the market. Based on the findings of the research, Petung bamboo laminated door frame, which also made from petung bamboo laminated beam, had the specific gravity value of 0.646 g/mm2, the compressive strength of 51.34 MPa, and the optimum flexural strength of 87.6708 MPa. The values of specific gravity test, compressive strength test, and flexural strength test are comparable to the class II of wood strength and applicable to use as door panels based on PKKI 1961

“…For material characterization purposes, researchers utilized synthetic compounds to modify the properties of the materials [4]. Furthermore, the density fluctuation practically differs from natural fiber to chemical substance; thus, the bulk of the agents comprising the composite material are thermoplastic and thermo-setting to make the material suitable for the application [5][6][7]. Researchers are developing biodegradable, ecofriendly, and synthetic polymers towards ecological sustainability.…”

Current research finds the suitability of natural fiber-reinforced polymer composites for industrial, automotive, marine, aerospace, and military vehicle applications, among others; they process being lightweight, high strength, ecofriendly, recyclable, and biodegradable. Bamboo fiber (Bambusoideae) mat, groundnut shell (Cocos nucifera) powder, copper particle, and multiwalled carbon nanotubes (MWCNT) fillers with epoxy resin are the primary materials. The key responsibility of MWCNT as a nanofiller is to improve the performance of materials by more than 80% and to attract the desirable properties such as high specific energy absorption of CNTs. An extensive investigation was carried out to determine the weight ratio between the total density and the water absorption rate of the composite. The maximal tensile and flexural strengths derived from EBGCM2 (E: epoxy; B: bamboo; G: groundnut shell; C: copper particle; M: MWCNT) were 50.66 MPa and 59.03 MPa, respectively. Addition of MWCNTs to specimens EBGCM2 and EBGCM3 and bonding the filler matrix by homogeneous mixing, but few nanoparticles are seen agglomerated. Flexural abilities of groundnut fiber/filler loading to strengthen the hybrid nanocomposites and the impact strength both quite improved than EB1 specimen. The neat epoxy and bamboo fiber composite (EB1) achieved 87.5 Shore-D hardness. SEM revealed (EBGCM3) improved interfacial adhesion between fiber and epoxy resin, but few nanoparticles are agglomerated, small molecules linked between the fibrous matrix, and the binding elements trapped in neighboring atoms, forming structural chains by the polymerization process.
