The elliptical tail throat uses this layer of carbon fiber composite material, which can avoid direct contact between the exhaust tail throat and the rear diffuser. In addition, we choose an epoxy resin system with a TG value of around 200 ℃ to further improve the high temperature resistance of the composite material. Without a doubt, having this layer of carbon fiber composite material does not mean it is permanent. Although carbon fiber can withstand temperatures of thousands of degrees, the resin used still has a certain temperature limit and is prone to melting. However, even if the epoxy resin is melted, the carbon fiber layer can still be retained (restoring the physical phenomenon of softness) and can also serve as a barrier. Even if this layer of carbon fiber composite material completely fails, replacing it will still achieve the initial repair purpose, which can reduce the frequency of replacing new parts.
