Resin vs Fiberglass helmet

[easystreet]

Hey all,

 

I have to make a choice between Fiberglass or Resin helmet. What are the pro's and con's?

 

Thanks,

Jason

They're fairly similar really. Fiberglass might be a bit lighter.

Thanks Work! Any pro's / con's to either?

Not particularly. Fiberglass might be a little bit more of a pain to work with due to the glass element but resin isn't that much better.

Fibreglass or GRP as it is also knows (Glass Reinforced Plastic) is essentially the same thing as a resin helmet, with one added facet. The Glass.

 

The glass matting is added in to add strength the resin and make it less frangible.

 

Basically a glass fibre matting is embedded into the resin of the helmet as part of it's construction process.

 

 

It doesn't necessarily make them any heavier, because you need less resin to create the same strength, so they can be thinner for a given strength.

 

Pros and Cons

 

It all depends on what resin the helmet is made from.

 

With a fast-cast PU resin, it's unlikely that they'll put in a glass matting purely due to time. I have seen it done, but it isn't common.

 

A GRP one can be stronger and less likely to distort, but again it all comes down to construction. As badly laid up GRP Mat can be just as fraught with danger as a badly slush cast resin one.

 

Always check the inside of a GRP helmet to see what the lay-up is like. If you can see dry patches or air bubbles where the matting has not been properly encased in the resin, then it will be weak and prone to failure.

 

Polyester resins can be a bit brittle.

 

GRP stuff is easy to repair with readily available repair 'kits'.
