AB -  At  the  present  there  exist  two  different  types  of  riot  helmet  shells,  a  thermoplastic  and  a 
composite shell. The composite shell is believed to be superior in impact performance, but more expensive 
and complicated in manufacturing partially due to the fact that the textile reinforcement material has to be cut 
into pattern pieces before they can be applied to the helmet shaped mould. However, the discontinuation of 
fibres is likely to reduce the level of protection and shorten the lifetime of a helmet. The aim of this research 
is to develop a helmet shell consisting of a single-piece of fabric without creating wrinkles and without the 
necessity  of  cutting  the  fabric.  For  this  purpose,  a  new  type  of  woven  fabric  has  been  developed  and  an 
apparatus has been set up to drape the fabric to a helmet shell. The helmet shell was manufactured using a 
single piece of Kevlar woven fabric. In parallel the finite element method is applied to investigate the shock 
absorption behaviour of the helmet shell made from both multi-piece and single-piece fabric reinforcements. 
The  results  show  clearly  the  advantage  of  the  single-piece  helmet  shell  over  its  existing  multi-piece 
counterpart.
