Abstract:

The various considerations underlying the specification and characterization of three-dimensional orientation distributions in moldings of short fiber reinforced polymers are discussed. The recommended treatment resolves the overall complex orientation pattern into distributions on a macroscopic and microscopic scale. Some examples, including the effects of molding conditions, are given for an end-gated rectangular bar plunger molded from fiberglass reinforced epoxy.
