In one broad aspect the present invention comprises the steps of providing a titanium-based material preform and superplastically forming the preform to a final helmet shape. In another broad aspect, a first piece of fiber-reinforced titanium matrix composite material is hot isostatically pressed (HIP'ed) to form a side wall section. A second piece of fiber-reinforced titanium matrix composite material is hot pressed to form an upper dome section. The side wall section is then HIP/diffusion bonded to the upper dome section.
