“…The results from the ANOVA indicate that the NI modulus and hardness of the fiber cell walls are influenced by bamboo ages significantly (P < 0.05) (Table 3), which is inconsistent with a number of previous studies (Huang et al 2016;Yu et al 2011;Yang et al 2014). Yang et al (2014) tested the mechanical properties of fiber cell walls of 2 to 5-year-old Dendrocalamus farinosus culms, and the results showed that the bamboo age had a highly significant impact on NI modulus (P < 0.01) but had significant effect on NI hardness (P < 0.05). The cell wall mechanical properties are closely related to the degree of lignification in culms.…”

“…This variation is likely due to differences in soil fertility, the climate of a certain year, and individual variations (Komuraiah et al 2014;Abdul Khalil et al 2015). The results from the ANOVA indicate that the NI modulus and hardness of the fiber cell walls are influenced by bamboo ages significantly (P < 0.05) (Table 3), which is inconsistent with a number of previous studies (Huang et al 2016;Yu et al 2011;Yang et al 2014).

“…This result contrasts with previously published research. Yang et al (2014) studied the cell wall mechanical properties of D. farinosus and found no significant difference in the NI modulus and hardness among the inner, middle, and outer positions of the culms (P > 0.05). Only minor longitudinal variations were found.…”

The cell wall mechanical properties are an important indicator for evaluating the overall mechanical properties of natural bamboo fibers. Using the nanoindentation technique, the variation of the mechanical properties of the fiber cell wall of Bambusa pervariabilis culms with different ages and different positions (both radial and longitudinal) was studied. Moreover, x-ray diffraction (XRD) was employed to measure the microfibril angle (MFA), and the correlation between the MFA and the mechanical properties of the fiber cell wall. The results showed that there was a remarkable difference in the fiber cell wall mechanical properties at different ages and at different radial and longitudinal positions. However, at different ages and at different positions, the absolute value of variation of MFA was less than 1° and was very minor. Furthermore, there was no significant correlation between the fiber cell wall mechanics and MFA, indicating that the mechanical property of the fiber cell walls might be synergistically affected by many factors.

“…The sclerenchyma fibers of the vascular bundles have been the focus of a number of mechanics investigations, including a numerical investigation of the molecular bonding of their microfibrils [23], nanoindentation [18,24,25] and studies of single fiber tensile properties [12,24,26,27]. Bamboo parenchyma mechanics, however, is less well studied; investigations of the parenchyma properties are generally limited to nanoindentation measurements [17,18,28].…”

“…It is a renewable and environmentally friendly biomass building material that is easy to obtain (van der Lugt et al 2006;Nurdiah 2016). Many scholars have performed research that has promoted the many applications of bamboo in building structures (Yang et al 2014;Askarinejad et al 2015;Dixon et al 2015). Many studies have examined the mechanical properties of bamboo by using small specimens (Lo et al 2004;Ray et al 2005;Tan et al 2011).…”

To study the flexural behavior of a composite beam, original single and double bamboo beams (SBBs and DBBs, respectively) and sprayed lightweight composite mortar-original bamboo composite beams (SCBs and DCBs) were designed and subjected to a four-point bending test based on the moisture content of the original bamboo. The failure modes, bearing capacity, and initial flexural rigidity of all of the beams were analyzed. Also, the strengthening effect of the lightweight composite mortar on the flexural behavior was studied. The results showed that a higher moisture content in the bamboo degraded the anti-slip property of the bond interface between the lightweight composite mortar and bamboo. The moisture content of the bamboo should be kept at approximately 20% before spraying. The initial flexural rigidity and bearing capacity of the DBBs were approximately 2.5 times and twice that of the SBBs, respectively. The initial flexural rigidities of the SCBs and DCBs were approximately 3.8 and 5.7 times that of the SBBs and DBBs, respectively. The ultimate load bearing capacity of the composite beams was approximately 1.5 times that of the original bamboo beams. It was shown that the lightweight composite mortar had a remarkable strengthening effect on the flexural behavior of the original bamboo.
