Short fibers as reinforcement are used in many structural applications in aerospace, automotive, machine building and civil engineering industries. Important part of fabrication technologies for such materials is base on structural element mould filling by liquid matrix with short fibers. Traditionally the matrix is viscous (polymers, fresh concrete). After maturing and demolding structural element mechanical properties are highly dependent on fiber distribution and orientation in the element body. For example, polymer matrix composite with short glass fibers or steel fiber reinforced concrete post cracking behavior and load –bearing capacity are dependent on the number of fibers crossing the weakest crack (bridged the crack) and their orientation to the crack surface [1-3]. This is why it is important to investigate this process.
