The manufacturing process is therefore simplified, which results in a more perfect ,material, balance. The result is a ,helmet, with all the same safety features as regular fibreglass, at about 80% the weight. Kevlar and Carbon Composite Shells
This ,material, is used to construct current in-mold and hard shell bike ,helmets,. The molding process of polycarbonate involves the bonding of the shell to the liner that produces a sturdy ,helmet,. This ,material, is of strong quality but lightweight at the same time. ,Materials,’ of the Three Important Components: Liner, Shell and Straps Liner
