4. Conclusions
The sisal/GFRP, jute/GFRP, sisal/jute/GFRP composite samples
are fabricated. The hybrids composite are subjected to mechanical
testing such as tensile, flexural and impact test. Based on the results,
the following conclusions are drawn:
-The results indicated that the jute composite material shows
maximum tensile strength and can hold the strength up to
229.54 MPa.
-The jute and sisal mixture composite sample is capable having
maximum flexural strength with a 14.2 mm displacement and
3.00 kN load.
- The maximum impact strength is obtained for the sisal fiber
composite and has the value of 18.67 joules.
-The internal structure and internal cracks and breaks are
observed for the broken surfaces of the tested composite samples
using Scanning Electron Microscope.
