Abstract
During carbon nanotubes synthesis a large amount of “defected” ones a re generated. The purification process involves, in general, high cost s. The market price of single walled carbon nanotubes (SWNT) with 99,999% purity is close to US$500,00/gram. To be able to use these defectiv e nanotubes as reinforcements for composites , their mechanical properties must be known . Considerable work has been done by Gates and his co -workers into the field of carbon nanotubes and composites reinforced by carbon nanotubes. However, the characterization of defective carbon nanotubes , also ca lled hetero -junctions, is still an open question. Notice that hetero -junction properties can have large variations, as those are dependent on the SWNT configurations. The so called molecular mechanics model is employed to investigate two defects configurat ions, i.e. Dunlap and Sadoc, and their stress concentration regions are located. These regions are the ones with the highest probability of failure. The model is validated against data from literature on non defective single walled carbon nanotubes with go od agreement.
