Treatment method and device used for composite cylinder surface

Abstract

The invention discloses a treatment method and device used for a composite cylinder surface. The device comprises a body with the upper end face and the lower end face provided with an upper mountinggroove and a lower mounting groove, the side wall of the body is provided with a glue blocking part and a glue scraping part, and a flow guide groove is formed in the upper end of the glue blocking part. The treatment method comprises the steps that the glue blocking part and the glue scraping part are placed towards a composite cylinder, a glue scraping strip is parallel to the composite cylinderin the axial direction, the glue scraping strip of the glue scraping part is in contact with the composite cylinder surface, the device exerts 5 N to 25 N pressure in the radial direction of the cylinder, the composite cylinder begins to rotate, meanwhile, the glue scraping strip does horizontal movement in the axial direction of the composite cylinder, and surface treatment work of the compositecylinder can be finished. The method and device are suitable for composite cylinder surface treatment with multiple winding methods without surface fibre damage, and the device is simple in structure, capable of effectively improving the composite cylinder surface quality, and capable of effectively solving the surface defects of composite cylinder surface fiber fluff, yarn breaking, bubbling andthe like, high surface treatment work cost and the like.

Description

technical field [0001] The invention belongs to the field of composite material molding, and in particular relates to a treatment method and device for the surface of a composite material cylinder. Background technique [0002] With the development of industry, composite materials have replaced the status of traditional steel and iron to a certain extent by virtue of their superior performance, and the superiority of composite materials is closely related to the molding technology and conditions of composite materials. Surface treatment is a key link in cylindrical molding of composite materials. The fiber layup is a single hoop winding, which can be wound with high tension. During the wet winding process, the fibers wound up later will squeeze the previous fiber layers, forcing the resin in the inner layer to continue to ooze out during the winding process. At the same time, since each layer is wound in a hoop direction, a scraping device can be used to remove the glue la...
