The history of science of composites, which started with the development of nano-structured nano-structured fibres, those being of carbon and boron, has provided us with a continuous row of the examples of close relationships between composite technologies and nanotechnologies. Nanostructures of fibres, matrix and fibre/matrix interfaces determine unique properties of the composites. If we are now on the eve of a new jump of the characteristics of structural composites and a variety of new fabrication technologies, we have to realize an importance of the composite-nano interactions.

Only some examples of the nature mentioned above are the subject of the paper. The author hopes that the continuation in a form of a new advance in the field of composites will follow.
