Hi all,


I took a couple of Rob Denney's testing suggestions and did them on a 1" 1'x2' panel of 6lb Aircell. Here are the tests and the results:

1) Took a hammer and hit the panel as hard as I could, 10 times in one spot

2) Took a 2x4 piece about 6" long, put it on the panel, then hit it with a hand sledge 10 times, very hard

After this, I cut the panel through each area.

The hammer test broke the fiberglass (1 layer of 18oz biaxial, infused with epoxy), dented the foam and delaminated the fiberglass around the area.

The sledge test slightly dented the foam and delaminated the reverse side of the panel.

I have uploaded photos to the "Aircell Testing" album on the harryproa yahoo group, under the Photos section, for anyone who wants to take a look.

Obviously, the panel failed these tests. My question is, was I fair, or was I too severe? Should I have only hit the panel once, instead of 10 times each? Should I not hit it as hard as I could?
