suggestions on my new fin design

[robertits]

Hello everyone, this is newbie on this forum. we are developing some new fin designs with flax material, but facing some airbubbles inside the fin, any comments or suggestions will be highly appreciated as we would like to finally apply such eco-friendly materials on shortboard or sup design.

Cheers

Hi Robert -

Many's the airbubble that's been bogged, sanded and painted over...

Could be the technique you're using, could be the nature of the material. I'm not sure what flax is exactly, but there are other "green" fibres being used - woven bamboo, hemp, linen, Jute - each with characteristics which lend themselves to some applications and not others. Some go brittle with resin, others are super-tough...and some might just make it difficult to lay up layers without airbubbles. Vacuum bagging is one way to squeeze the fnuk out of a laminate but can create other dramas.

So you may have to reveal a little more to get more than very general advice.

Hello JD,

Thanks for your reply!

what we do now is to laminate the flax fabric first, let it cure 100%, and then fabricate this cured stuff with other fiberglass, place into injection mold for final production.

Do you have any emaill account so that i could probably email u photo of final products for better understanding where the problem is and evaluate how it happens?

Cheers
