Modeling of void formation and removal in liquid composite molding. Part II: Model development and implementation

The objective of this Part II is to model void formation and their removal in LCM. From the micro‐scale flow pattern and void formation mechanisms observed by flow visualization, a phenomenological model based on the multi‐phase Darcy's law was developed to simulate the void formation during LCM mold filling. Results from Part I were used to determine several important parameters of the model. The model was able to predict macro‐void fractions with flow rates and liquid properties. A criterion for the movement of trapped voids was also developed.
