4 Conclusion
The strength of the product with other adequate mechanical properties is of paramount
importance for any rotomolded product. Much work is underway to improve the
strength of rotomolded product. For this process, LLDPE is largely used as a charge
material, since it deliberately provides unique flow characteristics. However, in
providing the requisite strength it finds its deficiency. Hence, an attempt is made
to blend LLDPE with Glass Fiber. An optimum mixture is an adequate requirement
for any prepared composite. So the experiments were performed to identify an appropriate blend of glass fiber with LLDPE. To achieve this, a dry mixture in powder
form was prepared with 15%, 20%, 25%, and 30% by weight fraction of glass fiber
mixed with LLDPE. The sample was then characterized, and the experiments were
performed using FTIR. The results obtained were in the form of the spectrum graphs
acquired by FTIR.
The peaks obtained resemble the distinctive characteristics present in the specific
sample being examined for the various compounds. LLDPE and glass fiber are maintained when 20% of glass fiber weight is combined with LLDPE. As a result, the
optimum blend can be suggested as 20% of glass fiber concentrated with LLDPE
ensuring adequate blend miscibility.
