Abstract

The unsmooth boundary of a cavity for the stage of filling glass fiber-reinforced polymer melt affects the flow property and the shape of the free interface’s shape, as a result, it will affect greatly the process, the degree and the location of the front interface, and the weld lines’ property and product quality as well. Here, the two-scale fractal theory is adopted to figure out the basic property of the unsmooth boundary, and governing equations are established in a fractal space. The numerical results can provide insight into the filling process and reveal the main factors affecting the shape of the free interface. The fractal interface is illustrated by the least-square method in different fractal spaces based on numerical simulation results. The fractal cavity sheds a new light on controlling the interface.
