CNT composites for aerospace applications

Abstract

Carbon nanotubes were synthesized by thermal arc plasma process after optimization of the synthesis parameters. These samples were then analysed by scanning and transmission electron microscopes (SEM and TEM), in order to establish the morphology of the nanostructures. Atomic force microscopy (AFM) and electron diffraction studies were also carried out before using the sample for the composite material preparation. Composites of epoxy resin with curing agent as well as a mixture of graphite and carbon nanotubes were prepared with varying proportions of the mixture. The electrical resistivity of the material was studied under varying pressure and voltage conditions. Preliminary results of these studies present interesting features which are reported here

Effect of dispersing nano-materials into structural adhesive on the electrical and mechanical properties

“…The shielding efficiency was enhanced by combination of different fillers in the same polymer matrix. Bellucci, et al [9] studied the resistivity of composite materials with varying percentages of thermal arc plasma processed CNTs added to the epoxy resin. The electrical resistivity of the material was studied under varying humidity, temperature and voltage conditions.…”

A stochastic approach towards a predictive model on charge transport properties in carbon nanotube composites

“…CNT exceptional electrical, mechanical, and thermal properties have been exploited in many studies to improve these properties in other materials. It has been observed that various polymers [10][11][12][13][14][15][16][17][18][19][20][21][22], ceramics [23,24], and epoxies [25][26][27][28][29][30][31][32] see enhancements in these properties when blended with CNTs to form composites. [32][33][34][35][36][37][38][39][40] The focus of this work is electronic transport in nanocomposites.…”

Modeling and simulation of the electromagnetic properties of composites filled by carbon nanotubes

“…Epoxy resin combined with carbon nanotubes (CNTs), principally of the multi-wall (MW) type, is largely adopted for the production of advanced composites that can be used in the aerospace industry [3,4]. In fact, driven by the significant weight reduction, such materials may be a valid alternative to the classical metal for the realization of structural parts in new generation aircraft fuselage or cockpit, for which ability to dissipate lightning currents or provide effective shielding again electromagnetic interference is required.…”
