How to project templates of carbon fiber for complicated surface?

Hello,


I'm studying on technical university and my job is to project (to model) the way the carbon fiber has to be put in mould which will be the negative of car body. In brief, my work will be used to create a body of a car of composites.

The problem is that the car body must be made of aerodynamic ,continuous shapes (no low-radius edges) so when the composite will be put then the unwanted folds may appear or that fiber will have to be cut in some places. I have no such an opportunity to make mould first and then put fiber on it as a test and given this, determine the way the templates should look like experimentally . I have to do it the other way round- I have to predict the shape of these templates given the 3d cad model of car body first.


So I would like to know are there any books, articles, methods etc, which tell how to cut that carbon templates for a given surface? Maybe there some graphics  which say how to determine the shape of these templates or software(I could import 3d model there)?

Thank you,Raportuj ten post

yes you can flatten in catia, and then generate a 2d ply shape, there is already a lot of work in this field especially motorpsort and aerospace where you need to create kits for layup.
I would also have a look at some of the nesting software for cutting tables as they may be able to give you links to applications on how to generate the files from 3D geometry
