Abstract: ABSTRACT THERMITON: AN INTEGRATED PROTECTIVE COMPOSITE MATERIAL SYSTEM, METHOD OF MANUFACTURE THEREOF, AND ARTICLES COMPRISING THE SAME [0127] The invention relates to an integrated protective composite material designated THERMITON, comprising a polymer matrix (UHMWPE/HDPE, 60-75 wt%) infiltrated into a sintered ceramic skeleton (20-35 wt% of ZrO2 3Y-TZP, Al2O3, h-BN, and YSZ), with carbon fibre reinforcement (1-5 wt%) and hollow glass microspheres (2-8 wt%). The composite achieves a density of 0.85-1.05 g/cm3, tensile strength of 800-1,200 MPa, compressive strength of 600-900 MPa, flexural strength of 400-600 MPa, Charpy impact strength of 80-150 kJ/m2, fracture toughness K_IC of 15-25 MPa m^1/2, and water absorption below 0.1% after 1,000 hours in seawater. The invention further encompasses: a skin panel variant for thermal protection systems with functionally graded layer architecture; a high-refractory THERMITON-HR variant with SiC aggregates and Al2O3 fibres for sustained thermal resistance at 1600-1800 degrees C; density-graded monolithic structures with superstructure (0.55-0.70 g/cm3), hull shell (0.94-0.98 g/cm3), and keel (2.0-3.0 g/cm3) regions for unsinkable, self-righting marine vessels; a resistive implant welding method using Ni-Cr wire implants achieving 90-100% joint efficiency; marine hulls and articles comprising the same; and a thermal recycling method achieving 85% material recovery.
