Winding forming device and forming method of woven belt of conic cabin

Abstract

The invention relates to a winding forming device and forming method of a woven belt of a conic cabin. The forming device comprises a first connecting disc and a second connecting disc which are arranged oppositely. The middle of the first connecting disc and the middle of the second connecting disc are connected through a center shaft. The first connecting disc and the second connecting disc areconnected through 2N outer pressing rollers and 2N inner pressing rollers. The 2N outer pressing rollers are arranged on the first circumference around the center shaft at equal angle and at intervals. The 2N inner pressing rollers are divided into N inner pressing roller sets, and the N inner pressing roller sets are arranged on the second circumference around the center shaft at equal angle andat intervals. The first circumference, the second circumference and the center shaft are arranged coaxially. The second circumference is located in the first circumference. Each inner pressing rollerset comprises two inner pressing rollers, and the two inner pressing rollers of each inner pressing roller set are arranged in a spaced manner. Smooth winding forming of the composite layer woven beltoutside the special-shaped complex-structure cabin with a large positive curvature structure and a large negative curvature structure can be achieved, and good practicality is achieved.

Description

technical field [0001] The invention belongs to the technical field of composite material forming, and in particular relates to a tape winding forming device and forming method for a tapered cabin section. Background technique [0002] Traditional aircrafts are of regular cylindrical or conical structure, and usually can be directly wound into shape by using regular overlapping winding and oblique winding. For the cabin section with large size and heterogeneous structure, its irregular shape and structure lead to large protrusions or negative curvature structures on the surface of the product. During the winding process, affected by factors such as the viscosity of the prepreg and the winding tension, it is easy to appear Poor bonding between the prepreg and the shell, debonding and delamination, etc., make it impossible to form the heat-resistant layer smoothly. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the present inven...
