Abstract

A gas-solid-liquid three-phase model is proposed for fiber reinforced composites mold filling process. The fluid flow is described in Eulerian coordinate while the dynamics of fibers is described in Langrangian coordinate. The interaction of fluid flow and fibers are enclosed in the model. The influence of fluid flow on fibers is described by the resultant forces imposed on fibers and the influence of fibers on fluid flow is described by the momentum exchange source term in the model. A finite volume method coupled with a level set method for viscoelastic-Newtonian fluid flow is used to solve the model. The direct dynamic numerical simulation for reinforced composites mold filling process is realized. The information about fiber transformation and orientation and interface evolution are obtained dynamically as well as the information about pressure and velocity etc. The skin-core-skin structure of fibers under different slenderness ratios during the mold filling process is captured which is in accordance with experimental results.
