One downside to ,ABS,, however, is that once damaged, it is mostly irreparable. Also, the manufacturing process that adds strength makes the ,plastic, more vulnerable to heat. Alternatively, making the ,plastic, to be more resistant to heat reduces its strength. ,Fiberglass,, in the application of motorcycles, is actually ,glass,-,reinforced plastic,.
It can then be combined with a ,plastic, resin, creating the carbon ,fiber reinforced, polymer known as carbon ,fiber,. When carbon ,fiber, technology was introduced to motorcycle ,helmets,, the benefits to riders increased drastically: Strength. Carbon ,fiber, motorcycle ,helmets, are stronger than those made with other commonly used materials.

While ,helmets, vary depending on the sport, they have the same basic components: To help absorb shock, the outer shell is made with hard plastics such as: carbon-,fiber,-,reinforced plastic, composites (used to make racing cars), ,glass,-,fiber,-,reinforced, plastics (often called ,fiberglass,),
Carbon ,fiber, (carbon for short): A trendy, very high strength ,fiber, replacing the ,glass, fibers in a ,helmet, shell. ... The outer surface of a ,helmet,, usually made of ,plastic,, ,fiberglass, or other ,fiber,-,reinforced plastic,. Skate ,helmet,: A ,helmet, designed for roller skating or skateboarding, typically made with a hard ,ABS, shell and small vents.
Fiberglass, (,fiberglass, and phenolic-impregnated textiles): Thermoset is material made from extremely fine fibers of ,glass,. Properly known as ,fiber,-,reinforced, polymer (FRP) or ,glass,-,reinforced plastic, (GRP). It has no true melting point but softens at 2.000° C.
