Embodiment Construction
[0048] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0049] The invention is used in the overall molding process of the heat-resistant material, and the porosity is filled with resin to form a rigid structure stage, and the size and shape control of the integrally formed heat-resistant structure product is realized by adopting the pneumatic shape dimensioning tooling and vacuum pumping and pressurizing technology.
[0050] Hereinafter, the present invention will be described in detail by taking a large-sized, integrally formed heat-proof structure of a reversible spaceship with a low-density fiber three-dimensional structure as a reinforcing phase as an example. The so-called large size means that the maximum projected area of the integrally formed heat-proof structure is greater than 2m 2 Structure.
[0051] Such as figure 1 As shown, the structure of the aerodynamic shape of the exothermi...
