What are motorcycle helmets made out of?

The conventional motorcycle helmet has two principal protective components: a thin, hard, outer shell typically made from polycarbonate plastic, fiberglass, or Kevlar and a soft, thick, inner liner usually made of expanded polystyrene or polypropylene “EPS” foam.

What are most motorcycle helmets made of?

Technically, most helmets are composite helmets. Fiberglass is inexpensive, lightweight and quite strong – a great combination when creating a motorcycle helmet. The lightest helmets out there will be composed of either Fiberglass or carbon fibre.

What materials are helmets made of?

The most visible part of the helmet is the outer shell that either comes in shiny or matte finishes. The outer shell is usually made of hard polycarbonate plastic or are other man made fibres such as kevlar or carbon fibre. depending on the type of material used for the price of the helmet may vary from one to another.

What are motorcycle helmet shells made of?

Inside the shell, all helmets contain a thick layer of expanded polystyrene, so-called EPS, which is a material that can absorb impact energy by irreversibly compressing itself.

What are helmet shells made of?

Skate-style helmets and a few bicycle-style helmets have hard shells made of ABS or polycarbonate plastic. BMX helmets and some bicycle helmets can have composite hard shells, with layers of fiberglass, kevlar or carbon fiber laid up in an epoxy. ABS is molded, but composite shells are generally laid up by hand.

What is the best material for a helmet?

Carbon/Kevlar helmets are the pinnacle of current helmet technology. These are remarkably tough shells that are close to indestructible. Making them is highly labor intensive, and as a result these helmets command a particularly high price.

What is the safest material for motorcycle helmets?


  • Carbon fibre helmets are generally the lightest, safest helmets out there. But they’re also the most expensive. …
  • If you’re on a tight budget, a thermoplastic (polycarbonate) shelled helmet is fine. …
  • Some expensive helmets are poor. …
  • If you want a really safe modular helmet, you need to be careful.

How are carbon fiber helmets made?

The way carbon fiber is made is by creating a carbon thread then weaving it into a material. … This is then set into a binder – usually a thermoplastic resin (the stuff that thermoplastic helmets are made out of) which gives it three dimensional strength. Using multiple layers together multiplies that strength further.

Is a polycarbonate helmet safe?

Polycarbonate plastic is one of the most common materials motorcycle helmets are made from. … Still, many great performing helmets continue to be made out of polycarbonates – including helmets that pass Snell testing or score the maximum five stars on the UK’s SHARP safety tests – so they’re well worth considering.

What is a composite helmet?

Composite-shelled crash helmets use a variety of different materials in their construction – typically a mix of fiberglass, aramid (Kevlar) and sometimes carbon fiber. The idea is you get the best of all worlds, strength, durability and abrasion resistance.

What is kinetic polymer alloy?

LS2 Helmets created their proprietary helmet shell material Kinetic Polymer Alloy (KPA). It uses nanotechnology to stretch and shrink aramid fibers down to where cross-sections are about 1 BILLIONTH of an inch thick and then encases them in a high-end polymer.

Is thermoplastic good for helmet?

Thermoplastic helmets, usually made from polycarbonate or ABS) are tough plastic helmets that are cheaper to make (and therefore tend to cost us less) but can make for fantastic helmets. Several thermoplastic helmets at the lower end of the price range have scored maximum points in the SHARP crash helmet safety test.
