Forming method and device for 0° laminate of composite materials

Abstract

The invention relates to a method and device for forming a composite material 0 DEG layer. The method comprises the following steps of: separating a pre-impregnated belt from back lining paper, compressing the pre-impregnated belt on the surface of a core mold through the compression roller under the action of a cylinder, rotating a belt laying head to make the laying direction form 0 DEG with the axis of the core mold, moving the belt laying head along the axis direction of the core mold under the control of a program, and laying up the pre-impregnated belt on the surface of the core mold under the pressure of the compression roller; when one travel is going to be completed, cutting the pre-impregnated belt through a pneumatic cutter to completing one travel; rotating the pre-impregnated belt by 180 DEG, rotating the core mold to a certain angle to make the surface of the core mold advance by the width of one pre-impregnated belt, and repeating the above procedures to perform continuous 0 DEG laying on the surface of the core mold. The invention provides a method and device for automatically laying and forming a 0 DEG layer on the surface of the core mold to replace the method for manually laying pre-impregnated cloth to form a 0 DEG layer, the forming efficiency is improved, and the scrap rate is reduced; meanwhile, glue content is easy to control and product quality is ensured because the pre-impregnated belt is adopted.

Description

technical field [0001] The invention relates to the field of composite material forming, in particular to a forming method and device for 0° layup of composite material. Background technique [0002] Composite materials, especially carbon fiber composite materials, 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. At present, the main manufacturing methods of composite materials include prepreg hand lay-up and filament winding molding. Manual lay-up mainly lays the prepreg fabric layer by layer on the mold according to the required size. Manual lay-up can realize lay-up in the direction of 0 angle, but the waste rate is high, the production efficiency is low and the quality is unstable; fiber winding molding It is not easy to pack closely, the design of winding angle is difficult, and winding of equ...
