An overview of material research and product development for polymer-b
ased composite materials since the 1950s in Japanese general industria
l use is given. This progress is divided into four steps, each lasting
about one decade; the trends of the fourth period (1984-today), follo
wing the third, transition period, are emphasised. In addition, as a f
uture perspective, the possibility of development of intelligent or sm
art materials is also discussed.
