    Impact tolerant bioinspired materials
    (Universidad Eafit, 2020) Estrada Hernández, Susana María; Ossa Henao, Edgar Alexander
    In highly demanding applications, such as sports protective gear and personal body armor, there is a growing demand for lightweight materials able to absorb impact energy while being flexible to allow easy movement to the user. These requirements are generally challenging for typical engineered materials since increased mechanical strength is usually associated with reduced flexibility and increased weight. Fortunately, this dichotomy has been successfully surpassed by natural armor through millions of years of evolution. Through biomimetics, this dissertation sought to introduce the functional principles of segmented natural armor into synthetic devices obtaining a family of cost-efficient materials with enhanced protection and flexibility. Remarkably, these bioinspired materials exhibited a minimum increase of weight enabling its implementation in personal protection applications.
