Energy absorbing properties of open-cell carbon foams were evaluated by quasi-static and dynamic compression tests. Though carbon foams show brittle deformation behaviors, they have wide plateau region. The plateau stress linearly increases with increasing the relative density. Furthermore, the strain rate sensitivity is 0.03 and 0.15 at low and high strain rate region, respectively. Indentation tests were performed on cylindrical sample having porosity of 92.3 to 92.8% with different impact speeds. No plateau region is observed and macro cracks occur in the high speed indentation test. The energy absorption efficiency of carbon foams is higher than that of conventional aluminum foams because of their wide plateau regions.

The Impact

This article focuses on the Finite Element (FE) analysis of the ballistic performance of the polymer composites consisting of natural rubber (NR), glass-epoxy (GE) and glass-rubber-epoxy (GRE) sandwich of different thicknesses (3, 6 and 9 mm) under the impact of the conical nose projectile for a velocity variation of (180, 220 and 260 m / s). FE modeling was carried out in direction to forecast the energy absorption, ballistic limit velocity and failure damage mode of the target materail. The significant influence of thickness, interlayer and sandwiching effect was studied: the lowest ballistic limit was obtained for 3 mm thick GE. Energy absorption capacity of GRE sandwich was highest among the natural rubber and GE. In future, the work can be extended for the experimental validation purpose, so that these polymer composite materials could be utilized to defence sector for bullet-proofing.
