With the development of industry, composite materials have replaced the traditional steel and iron status to a certain extent by virtue of the superior performance of the composite materials, and the superiority of the composite materials is closely related to the forming technology and conditions of the composite materials. The surface treatment is a key link for forming the composite material cylinder. The fiber lay is single hoop winding, and large tension winding can be used. In the wet winding process, the fibers on the later winding press the previous fiber layer, so that the resin of the inner layer continuously seeps out in the winding process. Meanwhile, each layer is annularly wound, and glue can be removed layer by adopting a glue scraping device in the winding process, so that residual resin is not much after winding.
The novel composite material cylinder is completely different, and because the middle layer of the composite material cylinder is spirally wound at a small angle, the winding tension can not be effectively applied, and meanwhile, the winding angle during spiral winding is very small, so that the glue can not be automatically removed. Therefore, the residual resin enriched in the composite material layer of the cylinder after winding is far more than that of pure hoop winding, and the cylinder is not easy to clean in subsequent surface treatment.
The surface treatment method of the existing composite material cylinder is characterized in that a PET (polyethylene terephthalate) film scraping sheet is bent into an arc shape to be in contact with the composite material cylinder, the cylinder rotates and the film scraping sheet horizontally moves along the axial direction of the cylinder to scrape the surface separated glue solution, and the surface treatment method has the following problems: (1) the PET material is softer, the contact surface with the cylinder is not well controlled after bending, and the frictioning force is not well controlled. (2) The cutting surface of the PET material frictioning piece is relatively sharp, and the fluffing and yarn breaking of the fibers on the surface of the composite material cylinder are easily caused.
