PURPOSE:To improve the physical properties of a formed body by spraying a heat-resistant metal and ceramics on the surface of the base material of a thruster or a mandrel, winding heat-resistant fiber, and uniting them to one composite body. CONSTITUTION:A heat-resistant metal or the metal and ceramics are sprayed on the surface of the base material of a thruster such as a jet engine or a rocket engine or on the surface of a mandrel, heat-resistant fiber is wound, and they are united to one composite body. In case of the mandrel, the mandrel is removed chemically and/or physically. Thus, the physical properties of a formed metallic body or a formed metal-ceramic body are improved. |
