How Are Motorcycle Helmet Shells Made?

Understanding Composite Material Manufacturing Techniques

Ever wondered how motorcycle helmets are made, especially their tough outer shells?

 

Dive into this detailed look at helmet safety and manufacturing on www.thehelmetdoctors.com!

 

When it comes to crafting motorcycle helmet shells, composite materials play a crucial role. There are two primary methods used:

 

Positive and Negative Mould Method: Here, a releasing agent and resin cover layer are sprayed into a negative mould. Thin strips of pre-cut glass fibre mats, soaked in polyester resin, are then manually applied layer by layer to ensure strength and durability.

 

Resin Application on Positive Mould: In this method, a layer of resin is first applied to the positive mould (the helmet’s foam inner liner). Aramid, glass, or carbon fibre mats are then layered over the resin to form a strong, uniform shell.

 

Both methods have their pros and cons. Composite shells offer lower initial costs but require meticulous manual labor, which can increase production expenses. They also demand additional finishing processes for precision and safety.
