Sergio Neves Monteiro, He obtained his Bachelor degree in Metallurgical Engineering at the Federal University of Rio de Janeiro, UFRJ, in 1966. Both his M.Sc., 1968, and Ph.D., 1972, degrees were obtained in the Materials Science and Engineering Department at the University of Florida, USA. He has taken an extension course in energy at the War College, Rio de Janeiro 1975, and a Post-Doctoral term at the University of Stuttgart, Germany 1976. He joined the staff of the Department of Metallurgical and Materials Engineering at the UFRJ in 1968 and became Full Professor in 1975, retiring 18 years later after 25 years of service. In 1993 he accepted the invitation to create the Laboratory of Advanced Materials of the State University of North Rio de Janeiro, UENF, where he was an active Professor/Researcher and retired in 2012. Presently he is a Full Professor at the Military Institute of Engineering, IME, Rio de Janeiro. He is the author of over 1,500 papers with more than 4,800 citations in the fields of plastic deformation, temperature effects, mechanical properties of metals and alloys; shape memory alloys, continuing engineering education; environmental engineering; advanced ceramics; natural fibers; natural fiber polymeric composites; alternative energies; technological programs as well as administration on science and technology. He served as advisor for over 80 M.Sc. and Ph.D. thesis and dissertations.

A proteção contra munição pesada (velocidade de projétil superior a 800 m/s) requer armadura balística de multicamadas. A primeira camada a receber o impacto de um projétil precisa ser um material duro e quebradiço (geralmente uma placa de cerâmica), que desgasta o projétil e dissipa a energia por fragmentação. A segunda camada deve ser capaz de capturar a nuvem de fragmentos. Para isso, um material convencional é o Kevlar, feito de fibras de aramida. Este trabalho mostrará que compósitos poliméricos reforçados com fibra natural / tecido podem substituir o Kevlar com vantagens significativas.
