“…The tensile strength of the mixed conventional filler with bamboo were found to be lower than the pure bamboo epoxy composites in most cases of different types of fillers. Compared to neat epoxy, the inclusion of bamboo fibres increased the tensile and flexural strength of the composites (Yu et al 2012) Bamboo is well-known for its excellent properties and wide use as the main material in structural applications. There have been many recent studies on its development (Tanaka et al 2007;Samal et al 2009;Sen and Reddy 2011).…”

Thermogravimetric analysis and differential scanning calorimetry were used to study the thermal degradation and thermal stability of bamboo powder and its composites (EP-BFC) in a nitrogen atmosphere. The thermal stability of EP-BFC decreased as the bamboo filler-loading increased. Compared with epoxy, bamboo powder had a lower thermal stability, which reduced the thermal stability for the higher filler-loading composites. The addition of glass fibre to the EP-BFC improved the thermal stability of the new hybrid composites. Both the hybrid and nonhybrid composites exhibited similar thermal-induced degradation profiles that had only one mass loss step. However, a noticeable difference between the percentage value of the degradation between both the hybrid and non-hybrid composites showed that the EP/G-BFC hybrids were more thermally stable than the non-hybrid EP-BFC. Different materials experienced different activities, which were clearly shown from the DSC analysis. Bamboo fibre and non-fully cured epoxy exhibit exothermic peaks, while fully cured epoxy exhibits an endothermic peak.

“…Efforts have been made even to mimic the structures of bamboo to design tough, strong, and still flexible nanoporous silicon using conducting polymers as a supporting material [16]. Bamboo/epoxy composites have been used to prepare special materials such as wood‐ceramics [17], footwear [18], and wind‐mill turbines. It was concluded that both sintering temperature and epoxy resin content have significant effects on the end use properties of the ceramics.…”

Aiming at development of completely biodegradable composite materials based on locally available low-cost bamboo flour (BF) as filler, structure properties correlations in aliphatic–aromatic copolyester/BF composites fabricated by melt mixing have been studied by means of different techniques such as electron microscopy, X-ray diffraction, tensile testing, and thermogravimetric analysis (TGA). It has been demonstrated that the BF can be successfully incorporated homogeneously into the biodegradable polymeric matrix up to high content. The filler weakly adheres to the matrix as demonstrated by the pulling up of bamboo fibers on the electron micrographs and further attested by TGA. At high filler concentration, the polymer acts merely as binding material. The semicrystalline framework of the matrix polymer is hindered by the presence of the fibers, the structural changes being more pronounced at the surfaces than in the bulk, which indicates preferential segregation of the fibers toward the specimen surface. This opens new possibilities for a more detailed engineering of materials surfaces. The mechanical properties of the composites are suited for low-load-bearing applications

Furan resin and fir powder pretreated by FeCl3 and aqueous ammonia solution were used to fabricate α-Fe/Fe3C/woodceramic nanocomposite. The bands of the pretreated wood powder were characterized by Fourier transform infrared spectroscopy (FTIR). The structural characterization of the nanocomposites was performed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The microwave absorption of the nanocomposites was measured by a vector network analyzer in the range of 2–18 GHz. The mechanical properties of the composites were also investigated. XRD and SEM results show that the α-Fe and Fe3C nanoparticles are in-situ generated and disperse in the matrix of the woodceramic. The diameters of these nanoparticles increase with the increasing of concentration of FeCl3 solution. The experimental results show that both the complex permittivity and the complex permeability of α-Fe/Fe3C/woodceramic nanocomposites increase as the concentration of FeCl3 solution increases. The composites pretreated with 0.60 mol·L−1 FeCl3 have the best absorption properties. The maximum value of reflection loss (RL) at 3 mm thickness reaches −25.60 dB at 10.16 GHz and the bandwidth below −10 dB is about 2.5 GHz. Compared to woodceramic, the bending strength and compressive strength of α-Fe/Fe3C/woodceramic nanocomposites increase by 22.5% and 18.7% at most, respectively.
