Materials
The term composite could mean almost anything if taken at
face value, since all materials are composed of dissimilar
subunits if examined at close enough detail. But in modern
materials engineering, the term usually refers to a “matrix”
material that is reinforced with fibres. For instance, the term
“FRP" (Fiber Reinforced Plastic) usually indicates a
thermosetting polyester matrix containing glass fibres, and this
particular composite has the lion's share of today's commercial
market.
Many composites used today are at the leading edge of
materials technology, with performance and costs appropriate to
ultra demanding applications such as spacecraft. But
heterogeneous materials combining the best aspects of dissimilar
constituents have been used by nature for millions of years.
Ancient society, imitating nature, used this approach as well: the
Book of Exodus speaks of using straw to reinforce mud in brick
making, without which the bricks would have almost no strength.
