Method for preparing hollow fabric sheet material

Abstract

The invention relates to a method for manufacturing hollow fabric sheets, which can accurately control the thickness of the hollow fabric sheets. The invention comprises the following steps: A. hollow fabric is compounded with resin; B. the hollow fabric compounded with the resin is put between an upper board and a lower board which are painted with parting agent, the boards are stuck to the surface of the hollow fabric under the action of force applied on the surface of the boards; C. the distance between the upper board and the lower board is adjusted to the preset value and fixed; and D. after the resin is solidified, the upper board and the lower board are removed, so a hollow fabric sheet is obtained. The invention has the improvement that a vacuum assistant resin permeation technology adopted in the step A enables the hollow fabric to be compounded with the resin. With the invention, not only the thickness of the obtained hollow fabric sheet can be accurately controlled, but also the thickness on every point of the sheet is uniform and consistent; meanwhile, with the adoption of the vacuum assistant resin permeation technology, the invention is easy to control the content of resin and has uniform distribution of the resin, thereby greatly improving the comprehensive performance of the hollow fabric sheet.

Description

technical field [0001] The invention relates to a method for preparing a hollow fabric plate, in particular to a method for preparing a hollow fabric plate woven with fibers of various specifications formed by a composite process. Background technique [0002] At present, when the hollow fabrics woven with various specifications and fibers are formed into panels of various specifications by a composite process, the method of manual coating is mainly used. This composite forming process has the disadvantages that the resin content is not easy to control, and the individual components of the same panel Point resin content is uneven. At the same time, the height of the hollow fabric sheet can stand up to a certain height by the pile warp of the hollow fabric through capillary action, which cannot be accurately controlled, and the thickness consistency of each point is also difficult to guarantee, which ultimately affects the comprehensive performance of the hollow fabric sheet....

[0002] At present, when the hollow fabrics woven with various specifications and fibers are formed into panels of various specifications by a composite process, the method of manual coating is mainly used. This composite forming process has the disadvantages that the resin content is not easy to control, and the individual components of the same panel Uneven point resin content

At the same time, the height of the hollow fabric sheet is determined by the velvet of the hollow fabric through capillary action to a certain height, which cannot be accurately controlled, and the consistency of thickness at each point is also difficult to ensure, which ultimately affects the overall performance of the hollow fabric sheet.
