チョップドストランドFRP板のステレオロジーによるモデル化とそのマイクロメカニックス解析

抄録

Micromechanical analysis is performed to the chopped-strand fiber reinforced composite material containing many clusters constituted by misoriented fibers. Equivalent expression for the fiber can be derived by using assumptions of both flat-ellipsoidal cluster and axisymmetric type of distribution of fibers. Then strain and stress fields induced in the composite are expressed explicitly. Moreover, by introducing the stereological concept into the model, the probability density function of profiles of fiber appeared on the side of plate can be expressed to the model.
