: --------------------

: Looking at either graph labeled "Total Absorbed Energy" and looking
: at the cross-grain .250" layups.

: The yellow (6oz & 6oz) and green (6oz & 12oz) are for all purposes
: identical.

: The red (4oz & 4oz) is even better than green (6oz & 12oz) in 2 of
: the four samples.

: That information might be what my comments were based on.

I did not mean to open old wounds.
Actually, I was referring to destructive testing of boat shapes. I realize the term would include any testing where the sample is lost but I'm more curious how various layups survive in more realistic situations. If the interior (compressive) side is where more glass would provide greater strength in flat panels it does not necessarily follow that it would be true in curved or hemispherical panels since they would not load the same. There is also the rigidity of the wood strips to consider in boat shapes since the rigidity of the wood is in one direction with the grain but the curviture would contribute strength at 90 degrees especially at the chines. It is possible that the wood core and shape could negative any theoretical difference between optimium and customary layups or it could accentuate them. I'm guessing now that the tests don't exist and the equipment to do such tests may only reside with the FAA or NTSB which are currently occupied crumpling Toyotas. The flat panel tests I have seen are more analgous to putting crash dummies in a tin can to see how strong the sheet metal is.
