Dynamic Mechanical Properties of CNTs/MoSi2 Composite Material
Carbon nanotubes (CNTs) are good reinforcement of composite materials,through add appropriate amount of carbon nanotubes to MoSi2 can be improve the strength and toughness of MoSi2.In this paper,the material of CNTs/MoSi2 was made through vacuum hot pressing technology.And the split hopkison press bar (SHPB) technology was used for testing the dynamic mechanical properties of CNTs/MoSi2 composite material which has different proportion of CNTs.In the SHPB experiment,in order to get better waveforms,the waveform shaping technology was used for improving the waveform quality,and also the strain gauge technology was used for testing the real strain of the specimen in the dynamic loading process.Through calculating,the dynamic stress-strain curves which under different high strain rate are given.At the same time,the strength,deformation and other test results are analyzed,and also compared them with the static compression experiment results of the CNTs/MoSi2 specimen which is tested by the electronic universal testing machine,and then obtained the dynamic performance of CNTs/MoSi2 composite material.
