Nano-additives are able to functionalize the materials to a greater extent or can even be used to produce hybrid composites [5,6]. Even the fibers can be composites themselves, for example, where microfibers or even nanofibers are reinforced with carbon nanotubes (CNTs) [7,8] or with nanoclay [9,10], etc. In these cases nano-reinforcement is typically embedded into a fiber which becomes a kind of matrix itself. These composite fibers can have excellent tensile properties [7] or can be used for detecting damage in composite structures [11] or can be precursors of carbon fibers [12].
