Modeling compsites for hand layup
Modeling compsites for hand layup
(OP)
Is anybody willing to share how they model hand laid carbon/glass composites in SW? I have a problem to solve with varying number of layers in various locations. What do mold shops like in a 3D model for this type of construction.

Then the parts are modeled in SW as surfaces. I wish they were linked.

I have had a shop ask for the SolidWorks model of a fibreglass enclosure. They converted the model to sheet metal and they flattened it out to figure out how to cut their glass fibre mat.
What do your fabricators say?

Are you trying to create the actual composite structure?
RE: Modeling compsites for hand layup
My part has varying thicknesses for stress and mechanical reasons. A simple shell(ed) model would not work.
The anaglyph and fibersym suggestions where some help. I haven't found anything that bills itself as a SW addin. For my purposes and if I had the money analgyph would make more sense because it helps the FEA figure out ply orientation. Maybe fibersim also does that but I didn't find it popping out on their website.
There are apparently two issues that need resolution. My question was specific to representing a composite layup to the manufacturer without knowing in advance who was doing the manufacturing. I don't know if there is an ASME standard for this.
CBL brought up the point of actually modeling a thin shell with varying thicknesses. This I know how to do.

"For actual composite part models, we use CBLs method."
While it's always nice to be given credit for doing something good ... the credit belongs elsewhere. I didn't mention "a thin shell with varying thickness", nor did I suggest a method.

If you do not have a manufacturer yet, you should go out and find one and ask questions. You could be digging yourself a very interesting hole!
