Abstract

The purpose of this research is to examine the absorbed energy, resistance to impact load of sandwich composite, and power exercised by impactor, experimentally. Therefore, low velocity impact tests were performed at three different energy levels for two distinct noses on sandwich composite with a PVC core and varying amounts of S2-glass layers. The vacuum-assisted resin infusion method (VARIM) was used to manufacture sandwich composites. S2-glass fabric with an areal density of 190 gm-2 and polyvinyl chloride (PVC) core material with a thickness of 10 mm were utilized. For every face sheet material, three distinct layer numbers of S2-glass fabrics were used. It is seen that composites exposed to flat impactors absorb considerably more energy than hemispherical ones.
