Impact properties of polymers
Polymer is made up from many chemically bonded parts or monomers that themselves are bonded together to form a solid. Polymeric materials such as PVC, nylon and nylatron are used as the specimen for this testing. In this study, the drop weight testing had been conducted to the specimens under t...

| description | Polymer is made up from many chemically bonded parts or monomers that
themselves are bonded together to form a solid. Polymeric materials such as PVC,
nylon and nylatron are used as the specimen for this testing.
In this study, the drop weight testing had been conducted to the specimens under
the impact loading using accelerometer. The drop weight was dropped on the
specimen from the different heights. The accelerometer is functioning as a sensor to
produce a voltage output which is proportional to the acceleration of the drop weight
where the accelerometer is mounted on it. The data acquired from the accelerometer
was then converted to acceleration, velocity and displacement. The stress-strain
curves were plotted in the further steps.
The results show that the voltage produced by the accelerometer is influenced by
the height of the drop weight from the specimen. At higher height, more impact
energy is available for the drop weight to knock the specimen. The results of the
drop weight testing also indicate that the value of modulus of elasticity is increasing
from nylon → PVC → nylatron at the same strain rate. This shows that the nylatron
has the highest strength among these materials. |
