Stress transfer within double‐walled nanotubes (DWNTs) in a composite is followed from stress‐induced Raman band shifts. It is shown that the Raman G′ band is split into two components, one from each wall. It is found that only the G′ component from the outer wall shifts with stress, and that this will limit the ability of multiwalled nanotubes to reinforce composites.
