Abstract: Apparatus and associated methods relate to an enhanced auxetic composite material (EACM) of a base thermoplastic elastomer (TPE) and/or a thermoset material combined with an auxetic material, the composite formed with a molding process, where the base material is injected or dripped into or injected, dripped or formed around the auxetic material, the composite material providing higher impact performance than the individual materials. In an illustrative example, combining various energy absorbing materials with auxetic materials may further enhance impact performance. In some examples, TPE material injected into auxetic structures may fill internal voids. In some examples, the auxetic material may be suspended within the TPE material and be encapsulated around the auxetic material form. Auxetic materials may take various forms, for example, sheets, 3-D structures, and particles, each providing unique benefits. Various embodiments included within various personal protection articles may advantageously provide long life and enhance impact resistance.
