Today, most bicycle helmets have
a three-part construction, a thin lining, a hard outer shell, and a strap
. Manufacturers will use polypropylene (EPS) or polystyrene to create a lining that is not too thick. The outer shell needs to be solid and durable, so polycarbonate or Kevlar is a good choice.
How are helmets manufactured?
The first way is by
using industrial adhesive, where a liner is stuck to an outer shell and taped around for the presentation
. The second method using which an outer shell can be made is by weaving two or more of the above-mentioned materials. This type of shell is called a composite shell.
What materials are used to make a bicycle helmet?
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.
How are most helmets created?
Helmet shells are made by
blow moulding, vacuum moulding or injection moulding

How are carbon fiber helmets made?
The way carbon fiber is made is by
creating a carbon thread then weaving it into a material
. Doing this gives it strength in two planes. 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.
