Abstract

The invention provides a method for molding the composite taper case 0-degree layer and relative device. First, slicing the constant breadth prepreg belt into two right-angle trapezia prepreg plates according to preset slicing length and angle, wherein, one is transcribed to one liner film after peeling off and first arranging it on the surface of taper case; turning core mould a certain angle, then arranging another one on its side edge to form a isosceles trapezia prepreg plates, while several this one can form the 0-degree layer of taper case. The inventive device adds a additive on the head of general layer, which comprises a air-powered instruction device, a additive flexible compression roller and a transcribed roller, while the air-powered instruction device and the transcribed roller transcribed the right angle trapezia prepreg belt, and the additive flexible compression roller is used to lay the transcribed prepreg belt on the surface of taper case. The invention can improve the molding efficiency, reduce the waste rate and reduce the producing cost.

Description

technical field [0001] The invention relates to a method and a device for forming a 0° layup of a composite material cone shell, and belongs to the technical field of automatic tape laying of composite materials. Background technique [0002] Conical shells are widely used in the aerospace field. Composite materials, especially carbon fiber composite conical shells, have the advantages of light weight, high strength, and high structural rigidity, and are used more and more widely. For example, the transition section between the carrier and the payload, the nozzle, the airborne radome, etc. According to the performance requirements, the composite material cone shell needs to be laminated with fibers in the direction of 0° to the cone generatrix to ensure the longitudinal performance. At present, the main manufacturing methods of composite cone shells include manual lay-up of prepreg and filament winding molding. Manual lay-up is mainly to cut the prepreg fabric into a fan s...
