The authors derived the method to obtain length distribution of visible part of fibers in transplanted matrix. The position and direction of the fibers in a high volume fraction composite are affected by adjacent fibers. In view of the fact, the authors assumed that fibers are coupled in the composite. Some useful results were obtained by numerical calculations. The direction distribution of the visible parts is unaffected by the distance between the coupled fibers, although the average length of the visible part decreases with the increasing distance.
