Characterization and Research on Mechanical Properties of Bamboo Plastic Composites

Abstract

The focus of this study was to observe the mechanical properties of bamboo plastic composites (BPCs) with bamboo pulp fiber (BPF) or white mud (WM). The essential work of fracture (EWF) methodology was used to characterize the impact toughness of BPCs. The results revealed an increase in flexural, tensile and impact properties, when adding the BPF in the BPCs. While the flexural properties of WM-reinforced BPCs revealed increasing, there was a decrease in tensile and impact strength. In an impact strength analysis study, BPF-filled BPCs showed excellent impact property over WM-filled BPCs; scanning electron microscopy (SEM) helps to explain impact fracture behavior of BPCs. EWF analysis of impact results showed that the specific essential work of fracture (we) increased significantly with the amount of BPF used in BPCs but decreased with the increase of WM in the BPCs. There was similar variation for the non-essential plastic work (βwp) of BPCs. This result indicates that the fracture initiation and fracture propagation of BPCs are different.

Characterization of Specific Essential Work of Fracture for various Fracture Modes on Thermoplastic Materials

“…Their conclusions are confirmed by recent research [23,24]. The EWF testing on natural fiber reinforced polymer composites showed that we increased significantly with the amount of bamboo pulp fiber used in bamboo plastic composites but decreased with the increase of white mud in the bamboo plastic composites [25][26][27].…”

“…The EWF testing on natural fiber reinforced polymer composites showed that the impact fracture toughness (w e ) was increased by increasing fiber content. Many researchers [18]- [25]- [32] concluded that the presence of fiber can increase the energy that is anticipated during the fracture process.…”

Effect of Polyphenylene Sulphide Particles and Films on the Properties of Polyphenylene Sulphide Composites

“…The impact performance test specimens included notched and unnotched samples. The results of the tests performed on the two types of samples were not significantly better than each other, but for the impact performance analysis of GF/PPS composites, the a cU values measured in the unnotched sample were the most conservative, so the unnotched sample was used, and the data were calculated in this paper [ 32 , 33 ]. The general equation for the impact strength of the unnotched sample is as follows: where is the impact strength of the unnotched supported beam, KJ/m 2 ; is the energy absorbed during the damage of the modified specimen, J; is the thickness of the sample, mm; and is the width of the model, mm.…”

Tailoring properties of polylactic acid/rubber/kenaf biocomposites: Effects of type of rubber and kenaf loading

“…A high intrinsic modulus of kenaf resulted in a stiffening effect in the biocomposites. The chain mobility and deformation ability of PLA and rubber matrices were restricted by dispersed kenaf particles (Ahmad and Baharum 2018;Xian et al 2018). However, the Alias et al (2020).…”
