Investigation of advanced mica powder nanocomposite filler materials: Surface energy analysis, powder rheology and sound absorption performance

Surface energy analysis (SEA) and rheology of powder milk dairy products.

Results of inverse gas chromatography adsorption/desorption experiments using selected probes on skimmed milk, whey and demineralised whey powder materials are presented. The dispersive component of surface energy was found to be dominant, indicating a low polarity character. Surface energy profiles of demineralised whey and skimmed milk showed a characteristic steep exponential decrease from a...

Rheology of Ceramic-powder-filled Polymer Melts

Ceramic powder (zirconia) was mixed with binder consisting polypropylene, paraffin and stearic acid in elastic extruder. Steady and oscillatory shear flow properties of these materials in the molten state were measured on a cone-plate rheometer; parallel superposed steady and oscillatory shear flow experiments were also carried out. Moreover, flow properties at high shear rates were measured on...

Potential of the magnesium powder as filler for biomedical composites

The intensive production of various biomedical composites made from different biomaterials showed a huge volume of information on properties of composite materials for appropriate research field. The matrix of composite materials is very important but the reinforcement materials known as fillers play an important role for the final properties of biomedical composites like mechanical properties ...

High-resolution Parallel-beam Powder Diffraction Measurement of Sub-surface Damage in Alumina-silicon Carbide Nanocomposite

The sub-surface damage in ground and subsequently annealed alumina/silicon carbide nanocomposite has been studied by analysis of the x-ray diffraction line width as a function of incidence angle. Bragg peak broadening fell as the depth of penetration of the x-ray beam increased. Despite substantial anisotropy in the uniform compressional strain in the surface of the ground material, no signific...
