Polyester resin & carbon fibre
« on: November 13, 2012, 10:13:52 am »

Having used carbon fibre cloth/balsa laminated with epoxy resin in a previous life building conpetition model aeroplanes I want to use the same carbon fibre to strengthen a (very) small hydro hull. For this I intend to use polyester resin for bonding but I have a niggling feeling that I've read somewhere there is a problem with the polyester/cf wetting coverage.
Advice please.

It's generally recommended to use epoxy resin- you get the best performance from the laminate that way, and epoxy is slightly thinner than polyester usually.

However you can use polyester resin okay, go for it.

Going to try it this evening. One of the reasons I asked was that I've got loads of polyester and I've run out of epoxy!

Thanks

Polyester works fine with carbon fibre its no different than using any other cloth i use it all the time,if your resin is thick put it somewhere warm before you mix it.

I've done the job now and can confirm that it works ok. Project has now stalled as all funds (ha ha) are being directed to an AA class BMPRS boat. However i will be doing some experiments on various laminate combinations in the near future.
