ABSTRACT:
A fiber composite material has individual reinforcing fibers embedded in a bonding matrix material. The bonding of the fibers to the embedding matrix material is controlled along the length of the fibers by axially spaced fiber surface bonding zones having a high bonding ability and alternating with further fiber surface low bonding or non-bonding zones having a low or no bonding ability relative to the matrix material. The bonding zones having a high or maximal bonding ability are distributed optimally as to size, location and spacing along the length of a fiber so that loads or forces including the breaking load are transmitted from one bonding zone to the next bonding zone which are preferably formed as ring zones. The low-bonding or non-bonding zones are so dimensioned that bonding zones of fibers located adjacent to one another do not overlap in a direction across the length of the fibers. The bonding and low-bonding or non-bonding zones are applied along the length of a fiber in a continuous manner, whereby different application methods may be used.
