Tribological performance of the blend PBT and short aramid fibers
Autor: Mihail BOTAN, Igor ROMAN, Constantin GEORGESCU, Alina CANTARAGIU, Lorena DELEANU
Publikováno v: INCAS Bulletin, Vol 7, Iss 1, Pp 29-36 (2015)
Polybutylene terephthalate (PBT) and its aramid fiber composite (10 wt.%) were investigated in order to measure their wear and frictional properties under variations of applied load (5 N, 10 N, 15N) and velocity (0.25 m/s, 0.5 m/s and 0.75 m/s), in d

THERMO-MECHANICAL PROPERTIES OF FABRIC REINFORCED COMPOSITES WITH FILED EPOXY MATRIX
Autor: Igor ROMAN, Vasile BRIA, Ion POSTOLACHE, Adrian CÎRCIUMARU, Iulian-Gabriel BÎRSAN
Publikováno v: Fiabilitate şi Durabilitate, Vol 2, Iss 6, Pp 53-56 (2010)
While the design problem seems to be essential in order to form a high performance composite one may ask more: is it possible to form a material able to give information about its state? Is it possible to control the properties of a composite through

THERMAL PROPERTIES OF PARTICULATE EPOXY COMPOSITES
Autor: Vasile BRIA, Igor ROMAN, Victor UNGUREANU, Adrian CÎRCIUMARU, Iulian-Gabriel BÎRSAN
Publikováno v: Fiabilitate şi Durabilitate, Vol 1, Iss 5, Pp 47-50 (2010)
The combination of a filler with a polymer results in a new material with changed properties. Some of these changes are advantageous while others are less favorable. Polymeric dispersions of nanometer-sized metal particles offer the possibility of fu

The 'Poetry' and 'Art' of the psalms in Ivan Franko’s prose (on the material of novel 'A thorn in foot')
Autor: Liliya Roman, Igor Roman
Publikováno v: Current issues of social sciences and history of medicine. :116-121
In the first part of the article "Poetry" and "art" of psalms in Ivan Franko's prose, "a contextual and ekstraxtual analysis of I. Franko's novel" Teren in the Leg "is presented. For the first time in the history of literary criticism, Psalm 31 is co

Neural Network Based Analysis of Tribological Behavior for an Epoxy-Clay Composite System
Autor: Igor Roman, Iulian Gabriel Birsan, Sorin Ciortan
Publikováno v: Applied Mechanics and Materials. :554-559
Prediction of a polymer properties, based on its composition, is a complex problem with no easy method to obtain directly and accurately results. Among the tribological properties, the friction coefficient and wear rate are the most interesting ones.
