The present work present a preliminary study to evaluate the impact response of a new sandwich panel, made up of two polyethylene skins separated by lightweight polyethylene foam. The material was built with an innovative manufacturing process called rotational moulding. To characterize the low-velocity impact response of this new material three homogenous polyethylene sandwich panels, 44±1 mm thick, was cut using a belt saw to obtain square specimen with dimension of 10±0.1 mm×10±0.1 mm and absorbed energy and force was recorded during the test. Seven impact test energy levels, from 5J to 70J, were tested. Experimental tests have allowed obtaining absorbed energy and the load-time plot for each impact energy level. Furthermore, a quantitative analysis of the damage due to the impact is presented.

Abstract

The present work present a preliminary study to evaluate the impact response of a new sandwich panel, made up of two polyethylene skins separated by lightweight polyethylene foam. The material was built with an innovative manufacturing process called rotational moulding. To characterize the low-velocity impact response of this new material three homogenous polyethylene sandwich panels, 44±1 mm thick, was cut using a belt saw to obtain square specimen with dimension of 10±0.1 mm×10±0.1 mm and absorbed energy and force was recorded during the test. Seven impact test energy levels, from 5J to 70J, were tested. Experimental tests have allowed obtaining absorbed energy and the load-time plot for each impact energy level. Furthermore, a quantitative analysis of the damage due to the impact is presented.
