AbstractThe intense progress in the field of nanomaterials contribute to search repeatedly novel combinations between the various classes of materials. As a result the nanocomposites are obtained that is two component system where in the matrix at least one dimension of the filler is located at the nano-scale. The main target of our study was the manufacturing process of nanocomposites fibers consist of thermoplastic polymer matrix -polyamides 11(PA11) and carbon nanotubes (MWCNTs) as a filler. The one of the major features of the polymer nanocomposites with CNTs is low percolation threshold, therefore the three-dimensional carbon nanotubes are able to conduct electrical charges even at low nanofiller contents. While the composites are produced as a fiber, the applied form of target product is veil - kind of fabric composed of previous extruded fibres with carbon nanotubes .The method of manufacturing includes, first of all, the homogenization process of carbon nanotubes with thermoplastic polymer then extruding the fibers from the previously made pellets and pressing them into the desired veil with specific weight and dimensions. Due to even a slight addition of carbon nanotubes into the polymer melt, the viscosity of the mixture significantly increases. Therefore the parameters of all processes were firstly adjusted and then optimized according to the stock of the filler. We managed to obtain the thin fibers containing CNTs from the range of 1% - 6 wt.%.
