Vacuum-assisted resin transfer molding (VARTM), one
of a commonly used composite manufacturing
processes, is becoming more popular. To optimize the
manufacturing process, reduce costs, and maintain
consistent part quality, knowledge of mold filling,
especially flow through thickness direction is
required. This work investigates the mechanism of
the thickness variation dynamic change during the
infusion and curing/relaxing processes. A numerical
model is developed to track the thickness change of
the bagging film free surface. In addition, this
work analyzes the sources of the...
