Modeling of anisotropic dual scale flow in RTM using the finite elements method

In Liquid Composite Molding (LCM) processes, a fabric reinforcement is placed in closed cavity and resin injected into the mold. Almost all reinforcements are dual scale containing fiber tows, which fill at different rate than region between tows. Simulation of LCM processes can help identify regions that fail to fill. However, presence flow usually neglected. Here this phenomenon modeled using Injection (LIMS) software complex network one-dimensional elements created. This allowed us simulate transverse longitudinal through tows taking consideration orientation architecture and, additionally, adding capillary effects model. A sensitivity study has been performed investigate properties non-dimensional form, allowing for comparison with experiments were conducted validate model by visualization front position area dimensions.
