AbstractIn this work, the effects of single walled carbon nanotubes (SWCNTs) on mechanical and electrical properties of two epoxy resins (a high temperature aerospace-grade epoxy and an aerospace-grade adhesive) were evaluated. The performance of these two SWCNT-modified epoxy resins was also studied in their end-use applications, as a matrix for a glass fiber laminate composites and as an adhesive for aluminum-to-aluminum bonding, respectively. The results suggest that the mechanical and electrical property improvements observed in bulk resin due the addition of SWCNTs do not necessarily translate into comparable property enhancements in laminates and joints. It was found that the electrical property improvements of nano-modified laminates exceeded those of bulk SWCNT-modified epoxy. The translation of mechanical properties from bulk resin to the structural level, on the other hand, was found to be less successful. The results are discussed in terms of challenges associated with processing and resin-fiber interaction.
