Fiber Orientation in Curvilinear Flow.

Abstract

It is well recognized that the material properties in fiber reinforced components are strongly dependent on the fiber orientation. In mold filling processes involving short fiber reinforced composites, fiber orientation occurs as a result of the flow induced stresses. It is important to be able to predict this flow induced orientation. A numerical method has been developed previously to predict the in-plane fiber orientation in plane flow. This scheme is refined to enable predictions for fiber orientation in axisymmetric flow. The numerical method is verified by comparing numerical and analytical solutions for fiber orientation in Poiseuille flow. The fiber orientation may be described by certain orientation parameters, which relate the degree of collimation to the material properties. These orientation parameters are incorporated into both the plane and axisymmetric flow algorithms, thus providing a link to available structural analysis routines. (MM)
