Rheological measurements and rheological shell model Considering the compressible behavior of long fiber reinforced sheet molding compound (SMC)

For a realistic process simulation of sheet molding compound (SMC), comprehensive and reliable viscosity data are essential. As the fiber-length in SMC is as long as the sample size of shear or rotation rheometers, an alternative rheology tool method was developed. To improve the quality of this method, a molding tool was equipped with seven pressure sensors. By means of this tool, compressibility of a semi-structural SMC was observed during …
