Natural fibers have been found to be excellent reinforcing materials for preparing natural fiber
reinforced thermoplastics (NFRT). From that, natural fiber plants like nettle are available in many
parts of Ethiopia. The main objective of this study is to fabricate and characterize the mechanical
property, such as impact, tensile and bending strength of nettle/glass fiber hybrid composite with
epoxy Resin. The hybrid composites were fabricated with nettle fiber: glass fiber: epoxy resin
weight percentage at [40%:0%:60%], [30%:10%:60%], [20%:20%:60%], and [10%:30%:60%] by
hand lay-up method. Once the samples were fabricated, the test pieces were cut according to
ASTM standards and the tests were conducted on Charpy impact testing machine and universal
testing machine. The maximum tensile strength, flexural strength, and impact energy were found
to be 248.44 MPa, 967.2 MPa, and 60.03 KJ/m2
, respectively as a function of fiber weight fraction.
According to the results, the hybrid composite with [30%:10%:60%] weight percentage exhibited
the best tensile and bending strength, whereas the [20%:20%:60%] weight ratio displayed the best
impact test compared to the rest proportions. The test results of the samples were also analyzed
using Finite Element Analysis with ANSYS software to validate the experimental results.
