INTRODUCTION The purpose of this project paper is to highlight the chemistry and science of the very curious material: Kevlar®. Our aim is to create a very informative piece of writing that can be of reference to our project subject‚ when in need. Upon taking up this project we conducted some very superficial research initially. Our research led us to believe that Kevlar® is a rather well known material that has been used in bullet proof vests for the last couple of decades. In addition to
