Effect of liner for single-piece continuously textile reinforced riot helmet shells

This work is a part of research carried out for the manufacturing and evaluation of riot helmet shells having continuous textile reinforcement. The paper is focused only on the effect of expanded polystyrene internal liner on the riot police helmet shells. Energy absorption and force attenuation at different position on the developed single-piece continuously textile reinforcement helmet shells have been studied. Low energy impact tests were carried out at different positions on the developed riot helmet shells. The result shows the internal liner plays a vital role in energy absorption and in force attenuation for a riot helmet shell.
