Wayne,

  It was documented via email - here's the data that I sent to Jim back in 
'03.


We set up an experiment to determine the Coefficient of Thermal Expansion 
(CTE) of the copper/epoxy composite.  We measured the contraction of an 
impregnated bar when cooled from room to liquid nitrogen temperature (294 
to 77 K).  The following data was recorded.

Room temperature - 21C (294 K)
Room temperature length of bar - 32.424"
LN2 temperature length of bar - 32.323"

This calculates to a CTE of 1.435 x10E-5 (in/in per degree Celsius)
