An experimental investigation to compare the flexural strength of a novel betel leaf fiber/cassia auriculata filler reinforced epoxy composite and betel leaf fiber reinforced epoxy composite.

Flexural strength evaluation of betel leaf fiber and cassia filler reinforced epoxy composites and comparison with betel leaf fiber reinforced epoxy composites. As a test group, betel leaf fibers and novel Cassia fillers were formed with 10% to 20% by volume epoxy composites (N=40). The betel leaf fiber epoxy resin composite without filler was used as the control group (N=20). The composite samples were prepared by hand lay-up method. Flexural tests were performed on epoxy composites containing the novel Cassia filler and unfilled at 10% and 20% by volume. The maximum flexural strength of the sheet-like fiber-reinforced areca nut-epoxy composite was 33.15 MPa, with statistically significant values of 33.11 MPa and 33.41 MPa for the 10% and 20% filler-reinforced composites, respectively (p=0.000; p<0.05) observed. Within the limits of this study, the bending of the betel leaf fibers of Cassia cassia foliage with a volume fraction of 20% compared slightly improved strength. [ABSTRACT FROM AUTHOR]
