Impact resistance study of high-density polyethylene through drop-weight and tensile impact tests

Abstract

This study deals with high-density polyethylene (HDPE) which was put to the drop weight and tensile impact tests. HDPE is very widespread thermoplastic polymer, especially in common applications such as packaging, consumer goods and car tanks. The injection moulded HDPE samples were subjected the drop weight impact test at six different potential energies (30, 50, 100, 150, 200 and 230 J) and measured data was evaluated. The second test was performed on pendulum test machine where impact resistance in tensile was studied. It was found out that HDPE is a low-cost material with high-performance properties in the field of the impact resistance which was evaluated in penetration and tensile test where the plastic deformation creates. © 2018 Trans Tech Publications, Switzerland.
