David,
I don't have all the data you requested, but perhaps this will help.
FR-2 is a phenolic resin system with a paper base. CEM-1 is an
epoxy resin system with a paper-glass composite base.
Flexural Strengths, (lbs/in^2):
Lengthwise: Crosswise:
FR-2: 12 000 10 500
CEM-1: 35 000 28 000
CTE (ppm/deg C):
FR-2: 12-25

Does anyone have any data on the properties of FR2/CEM1, I am
particularly interested in TCE, Tg and Young's modulus.
Thanks in advance.
