Abstract

Discontinuous fiber-reinforced composites are a special subcategory of composite materials that are used, due to the ability to process them into parts and structures of complex shape in an automated fashion via compression and injection molding, as well as extrusion processes. Discontinuous fiber-reinforced composites commonly consist of a thermoset or thermoplastic matrix material. The deformation that arises during flow results in fiber dispersion, fiber alignment, breakage and agglomeration, affecting the fiber orientation, length and density distributions. This seminar presents techniques that can be used to measure microstructure in the finished part, as well methods developed at the Polymer Engineering Center at UW-Madison to predict fiber orientation, length and density distributions in the finished part.
