Development of a Biofidelic Surrogate Scalp Using an Additive Manufactured Mold
Abstract
Biofidelic surrogate materials that mimic the mechanical response of the human skull and scalp serve as convenient and repeatable alternatives to using postmortem human tissue in survivability assessments of head protection equipment. Recent work at the US Army Combat Capabilities Development Command Army Research Laboratory has led to the development of a biofidelic surrogate of the human skull. This report outlines the development and validation of a compatible human scalp surrogate. Using the geometry from the surrogate skull, an additively manufactured mold was created, allowing for the injection of a scalp surrogate material. The scalp material was selected for its demonstrated correlation to the tensile response of human skin. Scalp surrogates were checked for dimensional consistency and through-thickness hardness (durometer) across the surface and compared to similar measures in human scalps from the literature.
