Mosi2 Composite

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.

Nanocomposites of acrylonitrile butadiene styrene (ABS) with multi-walled carbon nanotubes (MWCNTs) have been fabricated using a facile solution blending technique with the variable weight of MWCNTs in ABS within a range of 1–5 wt% in the ABS/MWCNTs nanocomposites. Morphological characterization using field emission scanning electron microscope has shown uniform dispersion of MWCNTs in the nanocomposites. Thermal gravimetric analysis has shown improved thermal degradation stability for 5 wt% ABS/MWCNTs nanocomposites in comparison to pure ABS. Thermal expansion analysis of ABS/MWCNTs nanocomposites also showed a significant reduction in thermal strain and coefficient of thermal expansion (CTE) in comparison to pure ABS, with the 5 wt% sample showing a maximum reduction in thermal expansion properties. Mechanical characterization for 5 wt% ABS/MWCNTs nanocomposite, using nanoindentation, showed significant improvement in elastic modulus (90%) and hardness (99%) in comparison to pure ABS. The dynamic mechanical properties of 5 wt% ABS/MWCNTs nanocomposites also showed significant improvement with storage modulus and hardness improving by 153% and 342%, respectively, in comparison to pure ABS. These enhanced thermal and mechanical properties of ABS/MWCNTs nanocomposites enable their applications for a wider scope in various areas of engineering-based application, especially in the automobile industry.
