A great many substances in na-
ture possess features that can
be used as models for modern
inventions. On a gram-for-gram
basis, for example, bone is
much stronger than iron.

Man-made materials eventually crack and shatter. This requires re-
placement or repairs, carried out with adhesives, for instance. But some

materials in nature, such as the mussel’s shell, can be repaired by the orig-
inal organisms. Recently, in imitation, scientists have begun development
of substances such as polymers and polycyclates, which can renew them-
22
selves. In the search to develop strong, self-renewing bio-inspired mate-
rials, one natural substance taken as a model is rhinoceros horn. In the 21 st
century, such research will form the basis of material science studies.

Composites

Most of the materials in nature consist of composites. Composites are
solid materials that result when two or more substances are combined to
form a new substance possessing properties that are superior to those of

the original ingredients. 23
The artificial composite known as fiberglass, for instance, is used in
boat hulls, fishing rods, and sports-equipment materials such as bows
