Hallo ;-)

I am making Robot arms in composite and have until now Normal closed cell foam in 10 mm as core.
But my parts has shape as a tube and is made at one time, not to parts glued together, the part is a free form shape with many round shapes, so now I want to use a core material there is more easy to form and better for infusion.

Here is a link to se the parts http://youtu.be/8PXKaC6_uJY   The Black parts is Carbon but alittle dusty :-)

But what is best ?

A)

     Layer 1 : 600g Carbon

     Layer 2 : Soric SF 3mm

     Layer 3 : 600g Carbon

     Layer 4 : Soric SF 3mm

     Layer 5 : 600g Carbon

Or

B)

     Layer 1 : 600g Carbon

     Layer 2 : 600g Carbon

     Layer 3 : 3D CORE PET 10mm

     Layer 4 : 600g Carbon

     Layer 5 : 600g Carbon

Take your pick really. I wasn't quite sure what part you're looking at making, but Soric is definitely the way to go if you've got a complex shape. The PET core can flex into shapes, but not so easy. It's more flexible rather than drape-able, compared to the Soric which is more like a heavy cloth. To be honest, I was left less than impressed with the thicker PET cores, but I also don't want to conclude that they are as poor as my crude testing found. 

Looking at your lay-ups, I think the PET core will be the better solution in terms of weight.
