Composite Layup

[ImnotfromMars]

Hello,

Does anyone know of a good reference text, standard, or instruction on how to draft and tolerance composite structures (eg. fiberglass panels, carbon fiber & resin etc...).

Well, obviously Y14.100 generally applies.

Y14.8 may be of some slightly more specific help

however I'm not aware of any similar standard specifically for composites.

Posting guidelines faq731-376

(probably not aimed specifically at you)
What is Engineering anyway: faq1088-1484​

Dimension and tol them like other parts. They can be molded and machined how you like.

ImnotfromMars,

GD&T is independent of fabrication process. What you need to know is what tolerances they can achieve, and what features they can do easily.

Talk to your fabricator. I recall that my tolerances were ±1mm, and that I needed 2[°][ ]draft angle on the sides. Then they fabricated my part, they asked for my SolidWorks model. They converted this to sheet metal, and they flattened it to get their material pattern.
