Hello all,
 I wrote late last year and asked if assistance could be give to make a mould for a F3 defuser. race car. and that a couple of attempts  had been made with a sad ending, and too the rubbish heap they went.

I have made a mould off the old defuser using glass etc.  and I thought I would use this as a mould for the defuser however, my troubles began when I used foam and carbon fiber to form the underneath ribs and when it was pulled down with the vacumm bagging process the ribs become out of shape under pressure.

I am no expert  with this process and I would appreciate assistance?.
Do you have to have  a split mould top and bottom to form the mould.

I would appreciate your comments, I will take a photo tomorrow and post it until then
Thanks
Sam
