The use of artificial (man-made) materials to replace lost or damaged biological soft tissue
has drawbacks, because the mechanical behavior of artificial materials fails to adequately
mimic that of soft tissue such as ligaments, tendons, and skin. These natural materials
exhibit large initial extension at small load, followed by a change to relatively little additional
extension at rapidly increasing load, giving a J-shaped load versus extension curve. We
have found that fibrous assemblies based on circular rings as a repeat unit can give both
the J-shaped load versus extension curve and the high overall extension of many biological
soft tissues. In addition, we have developed a criterion for design of and materials selection
for the fibrous assembly. This criterion, which relates inherent properties of the material to
the dimensions and extension ratio of the repeat unit, predicts the mechanical stability and
recoverability of the repeat unit, and therefore of the fibrous structure composed of the
repeat unit. The results of the study are promising for the development of soft tissue repairs
or replacements of man-made fibers.
