CVI (Chemical Vapor Infiltration) densification method for thick three-dimensional needled component
The invention relates to a CVI (Chemical Vapor Infiltration) densification method for a thick three-dimensional needling component, belongs to the technical field of composite material densification, and solves the technical problems of slow densification, difficult densification and non-uniform densification of the thick three-dimensional needling component. Carrying out CVI densification treatment on the main body flat plate blank; laminating and assembling; and a rivet welding treatment step. The CVI densification method is used for chemical vapor deposition densification of the thick three-dimensional needling component, a solution thought is provided for preparation of various special-shaped thick three-dimensional needling components, and the prepared thick three-dimensional needling component has the advantages of being uniform in density and excellent in mechanical property.
