Hi, I was wondering what would be the best method to make a cone for a 8" woofer.

I want to make a special shaped cone for a home made woofer. It must be light as possible but with a good strength.

I have bought a prefab. model to observe and that is made of 1 layer carbon fiber (very thin and strong but not smooth on surface you feel the fibers). (maybe made of pre. prep carbonsheet ?)

I prefer to make it with vacuum infusion because pre. prep is difficult to keep on stock. But is vacuum infusion more heavy as pre. prep? What is the minimum thickness? Would it make a significant difference?

The cone itself is at 35-40degrees angle. Is it possible to make it at home without folding or getting lines in the carbon fiber?

Thanks for your time.

hi,

-In theory Prepreg should be slightly lighter than Infusion but I properly vacuum infused you won't notice a difference (never did prepreg, will start soon with it, but that what I've read about is on the internet)
-The results of 1layer Vacuum resin infusion of carbon fiber 200g/sqm is almost like a 3sheets of paper, very flexible (a bit like a sheet of thin plastic). But due to it's shape it can get quit strong for it's thickness.
-It would be possible to make a cone shape with one sheet of carbon (easier to get 3D shapes with twill weave) you'll get a little distortion on the lines but thats what gives it charmes to a CF part?!

Merci Matthieu ;-)




Het is enkel "voorlopig" voor twee speakers. Het zou zo licht mogelijk moeten zijn om zo een hoger rendement + hogere frequenties aan te kunnen.

Te veel flex is ook niet goed geeft distortion door breakup. Zal het eens proberen nu ik weet dat het toch vrij dun kan met vacuum resin infusion.




Mvg,
