I was there yesterday briefly. It was mostly for big manufacturers, a little for smaller manufacturers. I didn't have professional time for listening to talks, I just walked the floor. I was looking to fix a few specific issues at work, not general research.
I found some interesting sandwich material that looks like you can infuse both sides of a panel at once easily.
When I dig thru my bag of stuff, I will post more. It is $50 to get in, but typically once you talk to some exhibitors, you get a free ticket for next time.
