This amazing material has a tensile strength about equal to that of alloyed steel, a density 1/6 that of steel, and a tensile strength about half that of some aramid fibers. Much research has been done to attempt to synthesize this material because of its many desireable properties. Kevlar is a strong polymer reacted from a carboxylic acid and benzenediamine. However, this material is composed of two proteins which contain two of the smallest amino acids, glycine and alanine. What is this material?
