Abstract

Natural fiber composite is the most preferable research area in the modern situation due to its availability, applications, and ecofriendly quality. This paper deals with the influence of hemp fiber with the various compositions of the ramie fiber and some basic mechanical properties of banana fiber composites. The hemp fiber is maintained as 20 percentage of total volume. Then, the remaining volume percentage is shared with the ramie fiber and banana fiber with various combinations. Eleven specimens were prepared to identify the some basic mechanical properties. The chemical compositions were mentioned as a pie chart, and then experimental results were plotted as graphical representations like line diagram and radar diagram for clear identification that the composite with higher ramie fiber concentration provided the greater results in the mechanical behaviors. The suitable composite combinations were recommended based on their superior properties as conclusions.

Highlights

Dipen Kumar et al [1] clearly reviewed about the fiber reinforcement composites with various industrialized methods, and they identified the characteristics with usage. ey discussed about the synthetic and natural fibers with the help of various images and evidences from the research articles
In this investigation, radar diagrams especially filled radar diagrams were used to realize the results in the clear identification. e experimental results of the tensile strength are plotted in Figure 6(a) as a radar diagram and Figure 6(b) as a line diagram. e tensile strength has enhancement from lower to higher with respect to increasing ramie fiber contribution among the composites
E highest tensile strength is achieved at specimen P11; the lowest tensile strength is achieved at P1

Summary

Introduction

E hemp, banana, and ramie fibers were separated; combination of these two or other fibers based composites was only studied This investigational research article is noticeably focused on natural fiber composites of constant twenty percentage of hemp fiber with banana and ramie fiber in different combinations of volume fractions and on the basic mechanical behavior (tensile strength, Young’s modulus, percentage of elongation and density) based appropriable volume fraction of fiber composites [22]. The maximum percentage of elongation range is between 38% and 48% for the specimens from P1 to P3; the lowest percentage elongation region is 3% to 12% for Figure 5: Testing machine for the investigation
