In this study, the theory proposed by the author to forecast distributions of length of visible part separated by other fibers and length of overlapping part covered with other fibers which could be observed under the surface of a short fiber reinforced composite was examined. For the examination, packing of fibers in space was computer simulated. The fibers were packed in a cubic space. Random numbers were used to assign position and orientation to the fibers. The computer-simulated short fiber reinforced composite was sectioned at a prescribed thickness. The sectioned simulated sample was observed from the surface, and the distributions of the length of the visible part and the overlapping part were measured. The obtained distributions and the average values of the length of those parts were compared with the distributions and the average values estimated by the theory. The distribution and average value of the length of the visible part estimated by the theory was almost corresponding to the simulational result. In the case that fiber orientation distribution was mostly random in three dimensions, the distribution and average value of the length of the overlapping part estimated by the theory was roughly corresponding to the simulational result.
