Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with specific examples and accompanying drawings.

[0037] Composite materials are used instead of figure 1 The metal materials are nested with complex topological piping structures, and composite materials are nested with complex topological piping structures, such as figure 2 , 3 As shown, it includes an inner composite topological pipeline 2, an outer composite shell 1 and a dimensional core material 3 between the inner composite topological pipeline and the outer composite shell. The wall thickness of the internal pipeline is 2mm, the wall thickness of the outer shell is divided into two thickness areas of 1mm and 3mm, the inner diameter of the main pipe is divided into two specifications: Φ76mm and Φ62mm, and the main body length is about 584mm.

[0038] The specific preparation process is as Figure 4 shown in the following steps:

Abstract

The invention provides a mutual-nested topology pipeline type structure and an overall forming method. The structure comprises an internal complex material topology pipeline, an external complex material shell and a form maintaining core material between the internal complex material topology pipeline and the external complex material shell. By adopting the concepts of multi-step pre-pressing andone-piece curing as well as flexible utilization of the form maintaining core material, the problem that molding and demolding of a one-piece complex structure with mutually nested pipeline and shellare difficult is solved, the integrity of the internal structure of complex material products is guaranteed, and the structural strength, the surface quality, the product preparation efficiency and the environment adaptability of products are greatly improved.

Description

technical field [0001] The invention relates to a mutual nested topological pipeline structure and an integral molding method, belonging to the technical field of composite material molding. Background technique [0002] Mutually nested complex topological pipeline structures are widely used in the intake and exhaust pipeline systems in the aerospace field and the transmission pipeline systems in petroleum, chemical, electric power and other industries. The structure is nested with complex topological pipelines. The structure is composed of an outer shell and complex topological pipelines nested inside each other, such as figure 1 The typical structure shown consists of an outer housing 01 and inner piping (single piping 03 and double piping 02). [0003] Mutually nested complex topological piping structures were previously formed with metal materials, but due to the disadvantages of heavy materials and poor environmental adaptability, the mutually nested complex topologica...
