Moi!
(Message is in English, my Finnish is very bad, sorry)
I'm a foreign student in Helsinki. I'm now working on a project, which is building a carbon/kevlar kayak from scratch.
I'm trying to find places to buy supplies from and so far found only 2 companies, one called "terpol" in Turku, one called "Kevra" in Helsinki/Vantaa.
They should both give me a price estimate, since the amount (and cost) of material is quite large, so I'm looking for the cheapest source of materials.
(also looking in Ebay and other countries of EU, mainly Germany)
I would like to know if anyone has any experience with composite boat building, and if they can recommend a place to buy, and give some tips about the project (this is my first boat-building attempt).
Thanks!

Low cost epoxy you find from Arsalin Oy Tampere , Jeti 500
But have you ever considered using wood instead of carbon fibers? Wood has some benefits over many other materials, it has excellent strength- , stiffness- and impact resistance to weight ratio - well matching with carbon fiber composite.
There is one technique to make ultimate structure from wood; the so called cold molding ; there you laminate reasonable width thin strips of sold wood veneers on /- 45 degrees to the keel line over mail mold. This wooden shell can be then coated with epoxy fiber laminate - glass fiber would give almost invisible coating leaving wood shine through , kevlar would give high scratch & impact resistant shield. Only thin surface laminate needed to protect the wood inside form water absorption.
But if not interested of using wood , then kevlar would make the work best being low weigth and extremely impact resistant material in epoxy composite.
MAke the whole hull skins of kevlar -epoxy laminate, and use carbon fibers only as special stiffeners and framing to give needed rigidity.
Remember that carbon fiber-epoxy laminate is very brittle and do not like the meetings with stones at all.
But before you buy anything, I strongly suggest you to study these materials as well as different boat building techniques a little more - it is not just that easy as just do it ..
Hello Jeti, Thank you for your reply.
I'm quite sure about the composition of the kayak, from the outside in, it is going to have these layers: a thin layer of fiberglass, 200gr/sq.m carbon, a 2nd layer of carbon, a layer of 3mm foam (Airex), another layer of carbon, and a layer of Kevlar.
The person who recommended this configuration is a composite expert (runs an aircraft factory) and a kayak lover. He advises me through the internet from time to time about the techniques and so forth.
What I'm interested in, is the challenge, so even if everything gets f*cked up somewhere along the way, I would still appreciate the experience :)
I would check the place you mentioned for the epoxy.
Any more ideas? Information?
Thanks.
Have you checked www.jacomp.net or their webstore www.comprocks.com. I can recommend their high quality UV-resistant epoxy: http://www.comprocks.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=43&category_id=34&option=com_virtuemart&Itemid=5 And ofcourse you find all other needed materials: fabrics, release agents etc...
