B2 Division process specification T-139A . The cold and elevated temperatures used for
testing were -125°F and 180°F, respectively.
bearing properties, most results are the average of data from six specimens. For the OHC,
OHT, and CAI properties, most results are the average of data from three specimens.
However, due to the loss of some specimens (either due to testing or instrumentation failure),
some results are the average of data from fewer specimens. The number of data points used
to calculate a particular property is given in the tables.
the measured ply thickness. The nominal ply thickness was determined by averaging all the
ply thicknesses of specimens used to determine mechanical properties for each material form.
The normalized values were calculated by the equation
