Tensile Properties of Untreated Bambusa Vulgaris, Gigantoch-loa Levis Gigantochloa Scortechinii, Gigantochloa Wrayi, and Schizostachyum Zollingeri Bamboo Fibers

Abstract

In the last couple decades, bamboo is getting interest due to the usefulness in textile application beside the most sustainable plant in earth. Textile fiber requires physically long, featherweight, and fine in diameter. Bamboo fibers impose high cellulose and lignin content. In a single fiber form, bamboo has very short physical length which lesser than 4 mm. This natural characteristic could affect the mechanical properties in fiber bundle or long fiber formation for textile processing. Besides, the extraction of long and fine bamboo fibers is significantly challenging over different species of them. Therefore, the tensile behavior of the untreated bamboo fibers over variety species shall be understanding in-depth. This study is about identifying tensile properties of bamboo fiber bundle of five commercialized bamboo species in Malaysia. Three regions of fiber bundles locations were extracted mechanically and tested. The long bamboo fiber tenacity and fineness were examined besides tensile strength and strain to failure value. Among those species, G. levis species demonstrated the highest tensile strength around 98MPa with strain to failure at 4.51%. G. wrayi (BT) recorded the coarsest fiber at 231 tex while the highest tenacity was obtained by B. vulgaris (MYK) at 10.88 cN/tex.

Mechanical characterization of bamboo pole for building engineering: A review

“…Figure 4b shows the difference in average tensile strength and MOE of three bamboo species, including Dendrocalamus asper, Gigantochloa scortechinii, and Gigantochloa levis. Twenty journals focused on the tensile strength and modulus of elastic (MOE) in tensile of three bamboo species, such as Javadian et al (2019), Jais et al (2020) and Rifqi et al (2020). Based on the tensile strength graph, the Dendrocalamus asper recorded the highest average tensile strength compared to other bamboo, 226.20 MPa.…”

“…Mokhtar et al (2018) has suggested a different perspective with specific allocation of green and air-dried condition in proclaiming the bamboo shear strength. Studies on bamboo tensile strength have suggested that Dendrocalamus asper is the top of the list (Awalluddin et al 2017;Amatosa and Lorento 2018;Jais et al 2020), while Gigantochloa levis shows higher tensile strength than Gigantochloa scortechinii. However, more investigation is needed to expand the quality of deducing this outcome for bamboo strength grading in the future.…”
