PDF] Correlating Structure Property Relationship of Kevlars by

Brand of para-aramid fiber, patented by DuPont called Kevlar. According to Mulkern and Raftenberg, “This material has a high strength (several times stronger than steel)” (2002, 13). For the first time Kevlar was obtained in 1964 by the research team Stephanie Kwolek (Hancox, 1993, 312). A production technology has been finalized a year later. However, commercial production of Kevlar began only in 1970 (Chaos.org.uk, 2015). The high strength and good thermal properties are the two most important qualities that are characteristic for Kevlar fibres (Brody, 1994, 113). The study of synthetic fiber’s features such as Kevlar is a very important practice today. Therefore, this work has relevance to modern scientific base. This paper focuses on research of structure and certain features of the Kevlar 29 and Kevlar 49. Especially, it is considered certain properties by birefringence and scattering (Toennies, 1973, 129). In the first part of paper, the author will consider the basic information about Kevlar 29 and Kevlar 49 for a better understanding of the research subject. Next, it will be introduced information about structure’s and other features of these materials. The next part of this paper will be considered two types of processes that can be applied to such types of materials as Kevlar 29 and Kevlar 49. This is especially considered mechanical, thermal and electrical-light properties of this type of fiber. The work uses a wide range of sources. First of all these are scientific works of various scholars from around the world which are more or less available to students. It also uses all available official information on the matter and objects that are considered in the work.
