Well, you're a thinker - I like that. But you're also a human who likes to complicate things; why? well only you can answer that... After the epoxy in which the straws are embedded has set, the presence of the straw is incidental.

Copper pipe or anything else will create an expansion differential across your lamination resulting in strain concentrations in your mould, and ultimately surface fracture.

LOL - I told you, I'd given much thought to arrive at what seems an idea that's just too easy to be optimum. (it's genius in a dirty straw disguise...lol)
