Hi guys,

I'm going to make a Carbon Fiber replica of a Keeper helmet 

http://www.talkcomposites.com/Uploads/Images/c5b69ec7-3b1b-4cfd-b0a3-cad0.JPGhttp://www.talkcomposites.com/Uploads/Images/853f1957-7024-4864-80fd-4160.JPGhttp://www.talkcomposites.com/Uploads/Images/0408d9dc-60d8-47e3-afcc-ea0f.JPG
It will be a Gelcoated mould and so on...thats not the problem I have...

The problem is:

The helmet I have now is made from PE (I guess it's just thermoformed)
I will need some carbon fiber and reinforcement but I don't really know what Lay-up I will need?
how many sheets of Carbon fiber, Fiberglass inbetween, some core, special resin,...

the helmet I have now weighs around 700grams
I want to make sure the helmet is stong enough so my goalkeeper won't get hurt :p 

If i'm not clear enough or if you have more questions please ask and I'll answer them as fast as possible!

kind regards Matthieu Libeert

Hi Matthieu,

Nice project, there is nothing wrong with easycomposites gel coat, for sure may in your case you need let it cure the gel coat first before looking next step for wet lay up process. in the easycomposites video tutorial, matt perform how to use the compatible gel coat.

Regard

Hey thanks for your response...
the thing is, I putted 2 coatings of gelcoat, One horizontaly (i've let it go tacky) then put another layer of gelcoat verticaly over the first one (not in video)
So the upperlayer got tacky and ive started the lay-up...everything went well untill I demoulded and saw the first layer Ive put was still tacky/sticky not cured...and thats what I dont get, because the mixing proportions were ok and I mixed it well... but no problem I will add a new layer today Smile
