Abstract

The low velocity impact response of thermoplastic honeycomb core from polypropylene (PP) laminated with non-metallic facesheet made from glass fiber reinforced plastic (GFRP) has been investigated by conducting drop weight impact test characterize with different drop heights displacement. Drop weight test was performed and average data was collected for each specimen, which is also included maximum impact force, impact energy, impact damage area, and time were evaluated and compared. The experimental result found that the energy absorbing effectiveness factor increases with the increasing of the impact energy. Same goes to the increasing of the impact force, it were also increasing the impact energy, respectively. A consequent damage was inspected visually and obvious when the impact energy is high, the energy absorbed by the specimen also high and hence, propagation of the impact damage area was also increased. Therefore, the significant mark of indented will be displayed clearly on the damage area mostly on upper facesheet.
