Mechanical characterization of polylactic acid reinforced bagasse/basalt hybrid fiber composites

Abstract

This paper focuses on the mechanical behavior of Polylatic acid reinforced Basalt and Bagasse fibers. The most important aspect in formulating this hybrid composite with better mechanical properties is the optimization of interfacial bonding between the reinforcing bagasse fiber and basalt fiber and polymer matrix. The composite of different weight proportion of the materials is compounded using twin screw extruder. The specimens were prepared by injection molding and subjected to various mechanical testing under tensile, flexural, and impact loads. It was found that 84 wt% of polylactic acid, 12 wt% of Basalt fiber and 4 wt% of Bagasse fiber composite exhibits better mechanical properties compared to other composites taken for study in this research. The better tensile, flexural, and impact strength of 52.8 MPa, 82.2 MPa, and 3.39 KJ/m2 were observed. The results show that the fiber content in weight percentage is playing a major than the fiber length on the improvement of tensile, flexural, and impact properties. The mechanical behavior obtained through experiments witnessed that Bagasse/Basalt fiber reinforcement in polylactic acid composites can be used as medium-load applications because of its low cost and ease of decomposability. The scanning electron microscope photography of the tested specimens shows better interfacial bonding between matrix and fibers. Also, the water absorption test indicates increase in fiber content increases the water absorption rate, reveals good degradation property of the composite. Additionally, the use of Bagasse fiber promotes the degradation of the material after its life time.

Mechanical properties of 3D printed micro‐nano rice husk/polylactic acid filaments

“…Different aspects of the PLA/RH6 and RH6‐KH550/KH570 composites were observed, with the appearance of some voids and cracks (Figure 6c–f), and the morphology of the interface between fibers and matrix was also studied. These features directly affect the permeability and mechanical property 45 …”

“…These features directly affect the permeability and mechanical property. 45 As shown in Figure 6c,e, it was found that some agglomerations and voids appeared on the surfaces of the two composites, which may be caused by poor adhesion/ bonding at the interface region. The condition of the RH6-KH550/KH570 composite was better than that of PLA/RH6 composite, the MNRH fibers were well involved in PLA matrix and distributed more homogeneously(Figure 6c,e).…”

A review on extraction, chemical treatment, characterization of natural fibers and its composites for potential applications

“…The fiber loading of 40 wt% with jute and banana fiber weight ratio of 1:1, 3:1, and 1:3 improves the micro‐hardness values by 113%, 123%, and 97%, respectively. King et al (2019) [ 219 ] conducted a mechanical properties analysis of PLA reinforced basalt/bagasse hybrid polymer composites. The results reveal that maximum tensile, flexural and impact strengths were noted at 52.8 MPa, 82.2 MPa and 3.39 kJ/m 2 , respectively.…”

Effect of saltwater on the mechanical properties of basalt/carbon/glass-epoxy hybrid composites

“…10 Besides carbon and glass fibers, the researchers employed basalt fiber as reinforcement because of its exceptional chemical, mechanical, and physical characteristics. [11][12][13][14][15][16] Wang X. 17 and Dhand V. et al 12 also stated interesting mechanical, thermal, and electrical properties of basalt fiber composites compared to glass fiber composites.…”
