Abstract
A one-step procedure to assemble nanoscale electrospun poly(methylmetacrylate) (PMMA) and multiwall carbon nanotube (MWCNT) reinforced PMMA fibers into twisted continuous ropes is presented. A post-treatment procedure following rope assembly is essential to maximize the mechanical properties of the ropes. A comparison between the mechanical properties of the individual nanoscale fibers and microscale ropes reveals that rope strength variability is advantageously smaller than single fiber strength variability, but also that the average rope strength is smaller than the single fiber strength. The incorporation of MWCNTs in PMMA ropes often leads to a significant increase in failure strain and toughness. [ABSTRACT FROM AUTHOR]
