Hello---

Currently, at my company we rely on multiple checks (buddy 
system) to verify the correct material is being used during 
multilayer lay-up.  We know that is not completely effective 
because of human error.  We are investigating automated or more 
reliable methods of material verification.  Weight verification, 
thickness verification, automatic prepreg dispensing, and machine 
vision are some of the ideas we are considering.

Does anyone out there have any experience with any automated 
material verification method during the multilayer lay-up process? 
Can you share with me some pros and cons of your system.


Thank you
