Abstract:

Polymer - based nanocomposite materials with carbon nanotubes (CNT) are novel materials which can hold the potential for airplane applications. One of the fabrication methods appropriate also for large scale is melt-mixing using masterbatch with a high content of CNT and fibre extrusion. Using this, nanocomposite fibres were obtained from polyamide 11 (PA11) with 2, 4 and 6 wt.% of multi-walled carbon nanotubes (MWCT), respectively. The addition of a compatibiliser, trade name MB50-011, was also studied. Fibres obtained were further cut and pressed into non-woven veils. The paper deals with the description of the process from pellets to veils, as well as fibres characterisation. The distribution of MWCT along the fibre length was studied using HRSEM. Also DSC analysis and electrical tests were performed.
