Thermal expansion of an E-glass/vinyl ester composite from 4 to 293 K

We have measured the thermal expansion of the three principal orthogonal directions of an E-glass/vinyl ester structural composite from liquid helium temperature, 4.2 K, to room temperature, 293 K. The linear thermal expansion at 4.2 K ranged from -0.23 to -0.71%, referenced to zero expansion at 293 K. We fitted the linear thermal expansion data from 4.2 to 293 K with a cubic polynomial for each of the three principal orthogonal directions.
