complicated the calculation of the cure shrinkage
coefficients. When compared to dilatometer data,
the BMS is much cleaner in determining CS and
CTE of the resin; however, it is available only for Tr
≤ 0. Future work will extend the temperature to the
limit of Tr = 0.05 to better understand the behavior
during glass transition. Future work will also focus
on detailed quantification of the temperature lag
and refinement of the BMS test procedure to reduce
the scatter observed at higher temperatures. Cure
shrinkage coefficient data obtained from the BMS will
be compared to previous models developed using the
dilatometer experiments as well.
