Background: The objective of this research is to evaluate the tensile, impact and flexural
properties of flax fiber and basalt powder filled polyester composite. Flax fiber is one of the
predominant reinforcement natural fiber which possess good mechanical properties and addition
of basalt powder as a filler provides additional support to the composite.
Methods: The Composites are prepared using flax fiber arranged in 10 layers with varying weight percentage
of the basalt powder as 5 wt.%, 10 wt.%, 15 wt.%, 20 wt.%, 25 wt.% and 30 wt.% respectively.
Results: From the results it is inferred that the composite combination 10 Layers of flax / 5 wt.%,
basalt Powder absorbs more tensile load of 145 MPa. Also, for the same combination maximum
flexural strength is about 60 MPa. Interestingly in the case of impact strength more energy was
absorbed by 10 layers of flax and 30 wt.% of basalt powder. In addition, the failure mechanism of
the composites also discussed briefly using SEM studies.
Conclusion: Flax fiber reinforced basalt powder filled polyester composites are successfully fabricated
by compression moulding method. Tensile, Flexural and Impact strength gets increased by
varying the flax fiber weight percentage.
