Composites profile, composite board and manufacturing method of composite board

Abstract

The invention discloses a composites profile. Upper and lower sides of an outer frame and an inner frame are fixedly connected through an upper frame and a lower frame; and the end parts of the upper frame and the lower frame are bent to form bending parts. An adhesive is stored in an adhesive storage tank of the composite profile, and a gap in the surface of the profile is supplemented, so that the adhesive effect of the composite board is improved. According to the composite board, two end parts of a sandwich panel are bonded to the inner frame of the composite profile; the upper surfaces of the sandwich panel and the upper frame are bonded with an upper cover board of the sandwich panel and the lower surfaces are bonded with a lower cover board of the sandwich panel. According to the composite board, the adhesive effect of the composite board is improved. A manufacturing method of the composite board comprises the steps of bonding the sandwich panel and the side surface of the inner frame; bonding the upper cover board of the sandwich panel on the upper surfaces of the composite profile and the sandwich panel; and bonding the lower cover board of the sandwich panel on the lower surfaces of the sandwich panel, the composite profile and an auxiliary connection plate. According to the manufacturing method of the composite board, the requirements of the operation process of a worker are reduced, thereby reducing the labor intensity of the worker.

Description

technical field [0001] The invention relates to the design and manufacturing technology of a composite section material and a composite panel of a high-speed magnetic levitation train body, in particular to a composite section material, a composite panel and a manufacturing method of the composite panel. Background technique [0002] With the development of high-speed maglev train technology, the requirements for the composite panels of the car body are getting higher and higher. Especially in the prior art, when the train speed is increased from 500 kilometers per hour to 600 kilometers per hour, there are higher requirements for the strength and weight of the composite board. [0003] However, in the manufacturing process of the existing composite panels, in order to ensure the strength requirements of the composite panels, the requirements for the amount of adhesive on the surface of the sandwich panels and composite profiles of the composite panels are becoming more and ...

AI Technical Summary

Problems solved by technology

In the prior art, usually the operator manually applies the adhesive to ensure that the amount of adhesive is as uniform as possible, not only to meet the required amount of bonding strength, but also to avoid too much adhesive affecting the bonding effect

[0004] It can be seen that the structural design of composite profiles and composite panels in the prior art is unreasonable and inconvenient for manufacturing

And in the production and manufacturing process of composite panels, the technical level of workers is high, which leads to the defect of high labor intensity
