Helmets are used as protective headgear for two wheelers. The typical motorcycle helmet has an inner layer of polystyrene or polypropylene foam and an outer layer made of plastic, glass, and other synthetic fibres. The chief purpose of a helmet is to absorb the impact of a crash and thus prevent primary injury to the brain, rather than preventing skull and face fractures. The outer shell is made from Acrylonitrile-Butadiene-Styrene (ABS) or Polypropylene or glass fibre plastic which is hard in nature. The inner side of the shell is expected to provide cushion to the rider and is made from regulated density concussion padding.
