<br><font size=2 face="sans-serif">No-the outer layer of woven fiberglass
(or other material) will dominate since the modulus of the fiberglass is
so much higher than any core material.The CTE may be a bit higher than
I posted due to the fact that most planes are a low fiber volume. The unidirectional
fiber pushrods are a near zero CTE.</font>
