Problems solved by technology
For cabins with large size and special-shaped structures, the 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 Problems such as poor bonding between the prepreg and the shell, debonding and delamination make it impossible to form the heat-resistant layer smoothly

Abstract
The invention relates to a winding and forming device and forming method for a tapered cabin section cloth belt. The forming device includes a first connecting plate and a second connecting plate oppositely arranged, the middle part of the first connecting plate and the middle part of the second connecting plate are connected by a central axis, and 2N connecting plates are passed between the first connecting plate and the second connecting plate. The outer pinch rollers and 2N inner pinch rollers are connected, and the 2N outer pinch rollers are arranged on the first circumference at equiangular intervals around the central axis, and the 2N inner pinch rollers are divided into N inner pinch roller groups, and the N inner pinch rollers The pinch rollers are arranged on the second circle at equiangular intervals around the central axis, the first circle, the second circle and the central axis are arranged coaxially, the second circle is located inside the first circle, and each inner pinch roller set includes two There are two inner pinch rollers, and the two inner pinch rollers of each inner pinch roller group are arranged at intervals. The invention can realize the smooth winding and forming of the outer composite layer cloth belt of the cabin section with a special-shaped complex structure containing relatively large positive curvature and negative curvature structure, and has good practicability.
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 special-shaped structure, its irregular shape leads to large protrusions or negative curvature structures on the product surface. 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 invention provides a ta...
