The research was primarily involved in developing a natural fiber composite and explore the impact properties of the developed materials as well as the homogeneity of the fiber dispersed in the specimen using melt mixing process.
Fiber: HEMP
Polymer: Linear low density polyethylene
Chemical: Naoh, Ma-g-PE
The impact testing specimen was attached to angle beam transducers to observe lamb waves that was generated due to the impact energy applied. The O-scope retrieves the signals from the transducer and deposited in a computer. Gabor Wavelet transformation is used to analyze the signals obtained from the impact to determine the characteristics of the composite.
Futher test was employed where real life defects were inflicted on the specimen to observe the difference in the wave propagation.

The raw fibers were chopped in a blender after the cryogenic process of dipping the fibers into liq. nitrogen. The blend of the fibers and LLDPE mixture is processed using Melt Mixing compounding machine at 50 rpm. Different types of testing specimens were molded using the compression machine.
The signals were obtain in different directional axis of the specimen to demonstrate the homogeneity of the of the specimen created using melt mixing.
Futher test was employed where real life defects were inflicted on the specimen to observe the difference in the wave propagation.
