Analysis of fiber orientation and fiber matrix separation in a compression molding process with an equi-biaxial flow front
Fiber orientation plays a decisive role in the mechanical characteristics of fiber reinforced plastics. During the flow process of the matrix several phenomena such as fiber matrix separation and fiber jamming can occur. This paper focuses on the effects of fiber aspect ratio, fiber volume content, fiber flexibility, initial mold coverage and viscosity of the matrix material on fiber orientation, as well as on fiber matrix separation in a compression molding process with an equi-biaxial deformation. Within this study, a mechanistic fiber simulation model was used, as well as simple experiments with model fluids and fibers.
