Stability of carbon nanotubes and fabrication and mechanical properties of carbon nanotube based composites

Abstract : The stability of carbon nanotube under self weight is analyzed by continuum method. Research results show that the critical aspect ratio can reach to 106. Double cantileveled beam model is used to study the pull in instability of two carbon nanotubes under van der waals forces. The obtained results are useful for the critical design of carbon nanotube based nanoswitch. Carbon nanotube/sic (cnt/sic) hybrid structure are fabricated by chemical vapor despositon. Different loadings of cnt/sic are added into epoxy resin to make micro/nanoscale hybrid composites. The static and dynamic compressive tests are first made to study the renforcement of different filler. Sem observation on the facture surfaces shows that both carbon nanotube and sic particle are dispersed homogeneously.
