Abstract
A two-plunger-type dilatometer was designed and fabricated to measure cure-induced volume changes of epoxy molding compound (EMC). The device is suitable for studying volume change of material systems that are fast reacting and with high conversions and high viscosity like commercial EMC. In this paper, the conversion rate was determined by DSC. Interactions of volume change, pressure, temperature, and conversion were measured. In the experiment, two different temperatures: 172°C, 180°C and four different pressures: 30, 50, 80, and 100 kgf/cm 2 were applied. The total number of conditions in this experiment is 8. Volume change of EMC due to thermal expansion, cure shrinkage, and thermal contraction under fixed temperature and pressure was measured. For higher pressure, the final volume change will be higher.
