Commonly used material is ABS (Industrial Plastics) and glass fiber. Good helmet carbon fiber making a useful, but expensive; 2, buffer layer (foam core) - the main function of the buffer layer is the absorption of external impact. If the hard shell helmet without buffer layer, in the event external shocks, external force through the hard shell directly on the head so that his head hurt. Therefore, the thickness of the buffer layer, the merits of the decision of the helmet material buffering capacity. Buffer layer mainly styrene foam material; 3, inner layer - the main role is to enhance the comfort when wearing, generally made of soft flannel; 4, line with - the role of which is to cap with a helmet firmly fixed on the head. The combination of the methods are: card camphor type, buckle; 5 lenses - eye care and facial mirror can play a protective effect, the materials are plastic (such as polycarbonate resin) and strengthen the glass (such as PMMA resin), etc., which reinforce the scratch properties of glass very well. In this proposal as a good material choice made retaining mirror, because the materials are less easily broken when hit and will hurt the face. Minor components include: gasket, stickers, hardware, paint, packaging and other accessories
