: Wood strip boats are easy: Glass/epoxy fails at 30,000psi, wood across grain
: at 300 psi - Ignore the wood.

: For plywood or cold molded: Glass/epoxy fails at 30,000psi, wood adjusting
: for the amount of wood in each direction and the specific gravity fails at
: 10,000-20,000+ (pounds per equivalent sq in of glass/epoxy). Glass serves
: a different purpose on plywood boats - mostly water control and abrasion
: resistance (that comes for free on wood strip boats).

I presume that a panel being tested is essentially acting like a beam. As I understand it, the neutral plane in a stressed beam is not in the middle of the beam but moves towards the tension side of the beam as stress increases. Given that on a kayak, impact stress occurs almost entirely on the outside, shouldn't the amount of glass on each side of the wood different, and therefore compensate for this, in an optimal configuration?
