Hi all,

I am looking for someone who have experience in mold making for a carbon fibre wing. As you see in the picture below.
http://cretiveproductions.files.wordpress.com/2013/09/s1223-2-stage-back-wing.jpg?w=800


I know that you should make 2 negative molds that splits the wing airfoil at the cordline, (splits the wing in 2 sides)
but do you have to make the upper an lower side of the wing in 2 pieces? and after it glue it toghether? or is there a way to just make the wing in one part?
Any advice?

thanks

You can cut foam with a hot wire in the profile of your wing.  Lay up some carbon on mylar and then wrap the carbon around the core.  Then bag the whole lot.  I put the core, bag etc back into the block of foam you cut the core from to hold it in shape while it cures.  This is great for one offs but not so good for production.

Yea sounds the most easy production method if you only need to make one wing... but would be great if we can make more Smile

If you build a wing for a real race car that produces real down force rather then just for the look you have to put in reinforcements like ribs spars and hard points for mounting.
That means you need to build it in two halves.

You can put fittings into the foam before you laminate onto it.  The foam acts as a support over the whole length so doesn't need ribs / spars etc.  The problem is its heavier than a sparred wing.  I have made wings like this in the past for pro-mods / pro-stocks.  My construction is 1x200g 2x650g onto blue foam.

Warren is indeed an expert on this one.  come on warren *poke*

To all members.
Give yourself a treat. Go to Georges site and digest the whole site. he is a master of the art.
I came across his site years ago and learned a great deal of tricks from him.
I have spent many hours going over every process that he has compiled, it was a mother load to me.

nice website you have there!!! Smile , and if you glue the two wing parts together (upper and lower) its with polyester glue? and after gluing it together do you need to add some coating at the outside again (in front of the wing, red line) ? or at the inside where i have drawn the red line... do you need to apply another CFR stroke ate the inside so there wan't be a gap?

thanks!

wings are best done with a small tab of cf on the inside of the joint line with adhesive in the butt joint and then sanded and polished down for a flush finish

these ones are done with internal ribbing



this is an f3 one which had a bit of a knock!
