NOVELTY - Manufacture of lightweight armor involves grinding particles of rare-earth material to particle size of 10-20 nm to create processed rare-earth material, mixing the processed rare-earth material with a positively charged aqueous dispersion to create a slurry, admixing said slurry to silica gel to create a rare-earth gel, sublimating rare-earth gel by increasing at least one of temperature and pressure, deposing rare-earth-material nanoparticles by decreasing at least one of the temperature and the pressure, dehydrating rare-earth material nanoparticles to form a nanoparticle powder, sublimating silicone graphene by increasing at least of temperature and pressure to created sublimated graphene, deposing graphene powder by reducing at least one of the temperature and the pressure of sublimated graphene, mixing graphene powder and nanoparticle powder to make graphene/nanoparticle powder, and admixing epoxy resin with graphene/nanoparticle powder to make nanoparticle epoxy resin. USE - Manufacture of lightweight armor e.g. lightweight bulletproof glass, armor, hardened casts, hardened portions, nonstructural reinforced hardened casts, structural shrapnel-resistant blocks, and attachable hardened surfaces. ADVANTAGE - The process provides lightweight bulletproof glass, armor, hardened cast, hardened parts, nonstructural reinforced hardened casts, structural shrapnel-resistant blocks, attachable hardened surfaces, and for hardening surfaces that overcome the disadvantages of the processes of the prior art. DETAILED DESCRIPTION - Manufacture of lightweight armor involves grinding particles of rare-earth material to particle size of 10-20 nm to create processed rare-earth material, mixing the processed rare-earth material with a positively charged aqueous dispersion to create a slurry, admixing said slurry to silica gel to create a rare-earth gel, sublimating rare-earth gel by increasing at least one of temperature and pressure, deposing rare-earth-material nanoparticles by decreasing at least one of the temperature and the pressure, dehydrating rare-earth material nanoparticles to form a nanoparticle powder, sublimating silicone graphene by increasing at least of temperature and pressure to created sublimated graphene, deposing graphene powder by reducing at least one of the temperature and the pressure of sublimated graphene, mixing graphene powder and nanoparticle powder to make graphene/nanoparticle powder, admixing epoxy resin with graphene/nanoparticle powder to make nanoparticle epoxy resin, grinding nanoparticle epoxy resin to particle size of 1 nm, admixing epoxy-resin hardener to nanoparticle epoxy resin to make a hardening nanoparticle epoxy resin, applying hardening nanoparticle epoxy resin to sheet of polyaramid to produce a nanoparticle enriched sheet, pressing nanoparticle enriched sheet to produce a pressed nanoparticle enriched sheet, curing pressed nanoparticle enriched sheet by applying heat to create a cured nanoparticle enriched sheet, and cold stretching the cured nanoparticle enriched sheet to produce a stretched and cured nanoparticle enriched sheet. INDEPENDENT CLAIMS are included for the following: (1) manufacture of hardened cast, which involves pouring the slurry of processed rare-earth material and the positively charged aqueous dispersion into the mold, curing slurry in the mold by applying at least one of heat and negative pressure until dry to make a hardened portion within the mold; and (2) manufacture of reinforced hardened portion, which involves applying the stretched and cured nanoparticle enriched sheet to hardened portion.
