The purpose of this research is to estimate fiber length in a 3-dimentional short fiber reinforced composite without extracting the fibers. The author leads the relationship between the fiber length and the number of visible parts observed under the composite surface based on the probabilistic method. The visible part is the section that the fiber observed under the surface is interposed between other fibers and so on. The number of the visible parts interposed between the embedded fiber tip and another fiber and the number of those derived from embedded fibers are evaluated separately. As for the number of the all visible parts, it is found out that the influence of the fiber length is not taken very much as the result of the numerical calculation. On the other hand, as for the number of visible parts interposed between the embedded fiber tip and another fiber and the number of those derived from the embedded fibers, it becomes clear that they are sensitive to the fiber length. It is pointed out that it is possible that the fiber length is estimated by using those numbers.
