Development and Application to Fracture Mechanics of Composites with Arbitrary Fiber Size

In order to analyze the stress distribution and stress concentration factors in composite materials, especially, in the short fiber of the reinforced composite materials by photoelastic method, it is necessary to develop the photoelastic model material having short fibers with arbitrary size and orientation. In this paper, the orthotropic photoelastic model material having short fibers for the transparent type photoelastic device was developed by the embedded corrosion fiber method. It was found that the model material was satisfactory to the properties of photoelastic model material, and also that the embedded corrosion fiber method can be employed for developing a model material with arbitrary size and direction to analyze the stress distribution and crack problems of composite materials.
