Abstract
This invention relates to a method of making a helmet using a preform subassembly with arms which have an area that matches a perimeter profile of a specified geometric shape. By use of the area matching perform with arms, the thickness of the helmet is more uniform, seams in the preform can be minimized, and the ballistic resistance of the resulting helmet can be increased.
