There were some pieces of 1/4" bare wood and 1/8" bare plywood. There was a plywood panel with kevlar and paint on one side. There were some thick cedar panels with glass on both sides. There were a lot of thin redwood panels with glass on one side and glass, kevlar or graphite on the backside. All of the panels had tags on them. I assume the glass side was the outside and should get hit by the rod. I Don't know what type of resin was used.

I dropped the rod from 20" and let it bounce until it stopped.

The rod went through the bare wood and bare plywood. Except for some whitening of the glass where the rod hit there was no damage to any of the panels.

I dropped the rod from 40" and let it bounce until it stopped.

The plywood with 1.7oz kevlar and paint was undamaged. The kevlar was the hit side.

The cedar panels were 3/16" and 1/4" with 6oz, 8oz, and 10oz of glass on both sides. The only damage to the 10oz panels was more whitening than before and a slight dent in the wood. The other panels had a nice round hole cut through the glass and the wood was cut and compressed maybe 1/16". The backside of the wood was split along the grain. There was more splitting on the 6oz panels. The glass on the backside looked undamaged.

There were 1/8" and .113 redwood panels with 9.6oz, 12.8oz, and 16oz glass on one side with glass or 5oz kevlar on the backside. There was more whitening than on the first drop. The rod bounced at least 2' high.

There was a .110" redwood panel with 3.4oz kevlar on both sides. The backside looked like the kevlar separated from the wood a little bit.

There were some 1/8" redwood panels with 3.2oz, 4oz, 6oz, and 6.4oz glass on both sides. The wood split along the grain and on some of them across the grain. On some the backside glass split across the grain

There were some other 1/8" panels. One had 5.4oz kevlar/graphite on both sides. The wood and backside material broke. One had 3.4oz kevlar on one side and 4oz graphite on the other. I hit the graphite side first. The wood split along the grain a little. I hit the kevlar side next at a different spot. The wood and graphite broke.

It helped me. Hope it helps you.
