The missile comprises a nose, fixed fins or movable fins, gas rudders, propelling nozzles and blast pipe inserts, combustion chamber liners, tail cone, grid fins, fluid elements and radome or subcomponents of these made of carbon fiber-reinforced silicon carbide (C/SiC) and/or carbon fiber-reinforce

The missile comprises a nose, fixed fins or movable fins, gas rudders, propelling nozzles and blast pipe inserts, combustion chamber liners, tail cone, grid fins, fluid elements and radome or subcomponents of these made of carbon fiber-reinforced silicon carbide (C/SiC) and/or carbon fiber-reinforced carbon (C/C) and/or silicon carbide fiber-reinforced silicon carbide (SiC/SiC) which are integrated in a missile structure. The missile components may be made of C/SiC and/or C/C and/or SiC/SiC with continuous fiber reinforcement and/or chopped fiber reinforcement or combinations thereof. The missile components may be prepared by mechanical machining of C/SiC and/or C/C and/or SiC/SiC blanks either in a single piece or by co-infiltration with carbon or silicon or silicon carbide and/or co-siliconizing of separate C/SiC and/or C/C and/or SiC/SiC segments to result in a monolithic structure. Cooling of the missile components may be achieved by providing cooling ducts and/or recesses in the C/SiC and/or C/C structure and/or the SiC/SiC structure and/or by means of insulating materials such as carbon fiber felts or C/SiC or C/C or SiC/SiC or graphite sheets or combinations thereof.

1. A missile comprised of components selected from the group consisting of a nose, fins, gas rudders, propelling nozzles and blast pipe inserts, combustion chamber liners, tail cone, fluid elements and a radome, and combinations thereof being made of ceramic material selected from the group consisting of carbon fiber-reinforced carbon (C/C), silicon carbide fiber-reinforced silicon carbide (SiC/SiC), and combinations thereof, whereby at least one of the missile parts possesses high density and low porosity to function as a structure selected from a thermo-mechanical mechanical support and a liner material, at least one another of the missile parts having low density and high porosity to function as a thermal insulation, with the density and porosity of the C/SiC material and/or the C/C material and/or the SiC/SiC material being controlled during infiltration or siliconizing by the amount of silicon, carbon or silicon carbide added.
