A solvent–non-solvent approach was used to create a CL-20-based aluminum-containing explosive with composite structure. The SEM results demonstrate that the aluminum powder is equally embedded on surface of CL-20 crystal in CL-20/Al structure but mechanically mixed agglomerated and spread unevenly. maximum expansion velocity 17.74% higher than cylinder test, acceleration ability wall superior explosive. In air explosion shock wave overpressure impulse are those explosive, as distance...
Tensile tests of two-dimensionally braided C/SiC composites and three-dimensionally had been carried out at room temperature. Some specimens unloaded during experiments. Acoustic Emission signals also collected The following conclusions were arrived. stress-strain curves these two materials nonlinear characters, there no obvious linear segments on those curves. Failure characters different: There appeared ply pull-out for 2D zigzag shape 3D specimens. Stress-strain loading-unloading showed...
In this paper, the effect of elevated temperature on behavior carbon fiber-reinforced T300/BMP350 unidirectional laminates was studied by loading static tensile 0°, 90°and ±45° lay-up. The stress-strain relationships under different temperatures were obtained. mechanical properties materials systematically studied. damage and failure mechanisms material analyzing curves modes. Results show that polyimide matrix composites have a strong resistance to high temperature. For 0° 90° lay-up,...
In this paper, using the finite element software PERFORM3D to establish analysis model for isolation and seismic frame structure with special-shaped column rectangular structure, overall of moderate strong elastic nonlinear earthquake time-history get dynamic characteristics, from two aspects damping coefficient in horizontal direction energy dissipation, investigation rare superstructure stiffness attenuation. It can be drawn only resistance measures are taken, under attenuation speed is...
The tensile damage evolution of 2D plain woven C/SiC composites strengthened with 1K and 3K carbon fiber bundles microstructure’s influence on material’s were investigated using the Acoustic Emission technology (AE) failure observation. Experimental results reveal that these two kinds is a gradual procedure this consists three phases. There no during first phase. During second phase, damage, mainly consisting matrix microcrack cracking, interface debonding joining microcrack, random takes...
Due to the shortage of natural raw materials, many practitioners proposed make concrete from desalinated sea sand. To reduce risk abuse uncleaned sand, we a new rapid test bar detect chloride ions in fresh quantitatively. The bars were prepared by mixing silver chromate with cotton fiber. By virtue high liquid-absorbent capacity fiber, chloride-contained liquid will rapidly enter into and react finally show certain coloring height, which corresponds actual content. In order optimize...
