Mechanical properties and microstructure of 2.5D (shallow bend-joint) quartzf/silica composites by silicasol-infiltration-sintering

Science and Engineering of Composite Materials, 2012
Silica composites (2.5D quartz fibers-reinforced) were prepared by the silicasol-infiltration-sintering method. The fiber volume fraction was 50.5%. The composites were sintered in a temperature range of 400∼450°C. Mechanical properties of the composites

Fractal characteristics and fracture mechanisms of flying gangue in longwall workings of the steeply dipping seam

Meitan kexue jishu
The flying-gangue hazard has long threatened the safety of personnel and mining equipment in steeply dipping/inclined coal seams. A flying gangue maybe produces a large number of “subgangues” after impacting on the longwall floor, it’s damage is sharply ...
