  • Description

    In the past, Dr. Kumosa worked six years (1985-1990) at the University of Cambridge in England. Between 1990 and 1997 he was a Professor of Materials Science and Electrical Engineering at the Oregon Graduate Institute in Portland, Oregon.

    Kumosa's research includes experimental and numerical fracture analyses of advanced composite systems for electrical and aerospace applications. He has performed sponsored research for a variety of private and federal funding agencies in the US including NSF, AFOSR, NASA, EPRI, GE Aircraft Engines, BPA, WAPA, APC, PGE, etc.

    Kumosa has published over 90 publications in major international composites, materials science, applied physics, applied mechanics and IEEE journals, plus 45 publications in international conference proceedings. He has also supervised twelve Ph.D and eight MS theses. Dr. Kumosa is on the Editorial Board of Composites Science and Technology, the #1 international journal in composite materials with the highest Impact Factor.

    Personal interests: gardening, piano, world history, investing, fishing, ATVinng, etc.

  • Areas of Research

    Kumosa's primary research interests are related to the application of advanced polymer matrix composite systems in extreme environments (such as very high and very low temperatures, high voltage, stress/strain, moisture, corrosion, ozone, UV radiation, or other degradation conditions).

    Under these extreme conditions, both man-made and natural composites for aerospace, electrical, automotive, bioengineering, construction, electronic, etc. applications disintegrate with time changing their physical, chemical and mechanical properties.

    Kumosa is especially interested in developing both experimental and numerical tools, which could be used to predict and prevent these changes in a variety of composite structures based on polymers.

    We have been especially successful applying our research approaches in the failure analysis of high voltage composite insulators and high temperature polymer matrix aerospace structures. These are briefly described below.

    Composite high voltage insulators are widely used in transmission line and substation applications in the US and abroad. In service, the insulators are subjected to the combined action of extreme mechanical, electrical and environmental stresses. Due to the presence of these stresses, catastrophic failures of the insulators have occurred over the last several years in many regions of the world. The primary goal of our insulator research has been to understand the fundamental mechanisms leading to the premature mechanical and electrical failures of the insulators in-service and to improve the design of the insulators.

    Jointly with NASA Glenn, Boeing, Air Force Office of Scientific Research and several other major US industrial and academic organizations, we were involved in the development of multidisciplinary technologies for affordable propulsion engine components that will enable the system to operate at higher temperatures with reduced cooling, while sustaining performance and durability. As part of these efforts, high temperature polymer matrix composites and fabrication technologies were developed suitable for manifolds, thrust chamber supports and attachments. The usage of such composites allowed the replacement of heavy metal engine components to provide a high thrust to weight ratio.
