A multilayer helmet shell wherein inner and, outer, structural, load-bearing semi-rigid layers, each formed from an affinity-bonded agglomeration of mechanically interactive, spray-deposited particles, jacket a viscoelastic, acceleration-rate-sensitive, microcellular foam core layer. The mechanical interfaces between the inner and outer jacketing, and the intermediate core, materials take the form of regions of inter-material suffusement.
