確率論に基づいた短繊維強化複合材表面下に存在する繊維の投影長さ計算モデル

抄録

The so-called 'complete projection length' and 'incomplete projection length' of the fibers under the composite surface were theoretically derived, assuming that fibers could be observed from the surface. The whole of the fiber cannot be always observed because some other fibers frequently overlap the fiber. The position and the width of the overlapping part were derived based on the probabilistic theory. Variations of the complete projection length and the incomplete projection length with the fiber length were calculated, and it was examined about the possibility of the fiber length distribution estimation by this theory. Furthermore, it was examined about the influence of the several factors on the complete projection length and the incomplete projection length.
