Machining of thermosetting composites by means of milling and drilling

Polymer composites are widely spread in machinery, construction activity, incl. production of wear plates and items of fitting systems. In process of manufacturing items from composites, the products must be machined by tools and cutters. During cutting, with mechanical and thermal loads applied, the destruction of composites takes place to deteriorate quality of products. To increase quality of products, the procedures of cutting modes calculation should be developed with introduction of correction factors considering specific properties of polymers, as well as their optimization with usage of multi-criteria methods. © IDOSI Publications, 2013

Parameterization of microstructures in material science and material technology

The article deals with possible applications of multi-fractal parameterization of microstructures (MFP) fields of material science and welding. MFP is successfully used for fine selection of microstructures, specification of thermal treatment modes and others. Experimental data were recorded for samples manufactured from steels of austenitic class. The research also comprises data on dependence of grain size upon multi-fractal parameters of uniformity and orderliness got by other authors. The study suggests algorithm of predicting Vickers hardness on basis of multi-fractal parameterization of metallographic specimen by means of calculating the parameters of uniformity and orderliness. Program created on basis of algorithm allows analyze microstructure to determine the grain size. © IDOSI Publications, 2013

Influence of particulate fillers on complex of dielectric properties of rigid and plasticized PVC compositions

The article discloses efficiency of modifying the polyvinyl chloride by organic and mineral fillers being the wastes of various industrial productions. Main dielectric properties of rigid and plasticized compositions were examined, for different combinations and ratios of modifying additives. The article displayed how the particulate fillers nature and composition influence on character and intervals of dielectric behavior modification. The results of researches were interpreted with consideration of structural-morphological composition of polyvinyl chloride, of modifying additives' nature, content and ratio. © IDOSI Publications, 2014
