A kind of processing method of gfrp panel

Abstract

The invention provides a processing method of a GFRP (Glass Fiber Reinforced Plastic) panel. The processing method comprises the following steps: laying a lower-layer vacuum membrane, glass fiber cloth, upper-layer de-molding cloth and an upper-layer flow guide net on a mold in sequence from bottom to top; sticking a material for adhering on a part which extends out from the lower-layer vacuum membrane; arranging at least two groups of guide pipes at a part which extends out from the upper-layer de-molding cloth; then laying an upper-layer vacuum membrane; connecting the upper-layer vacuum membrane and the lower-layer vacuum membrane to form a sealed structure; connecting the first guide pipe with a vacuum device and connecting the other first guide pipe with a resin container; filling theresin container with resin and opening the vacuum device; after the guided resin and glass fiber cloth are completely wetted, cutting off the connection of the vacuum device and the resin container,and the corresponding first guide pipes; curing to obtain a cured plate; removing a surface auxiliary material and chopping leftover materials to obtain a GFRP panel finished product. The processing method provided by the invention has the advantages that the cost can be saved and the precision of the panel can meet engineering requirements.

Description

Technical field [0001] The invention belongs to the technical field of civil engineering, and relates to a processing method of a panel, particularly a processing method of a GFRP panel. Background technique [0002] Due to the requirements of building curved surfaces, the use of traditional curtain wall materials is subject to certain restrictions. As a new building material, GFRP has excellent performance compared to traditional curtain wall materials, especially processing performance, so it is an ideal free-form surface curtain wall material. However, because the traditional GFRP (glass fiber reinforced plastic, commonly known as glass fiber reinforced plastic) board processing method is more complicated, wet work, poor sanitary conditions, high labor intensity, low production efficiency, resulting in high panel production costs, long construction period, and for curved molds There are certain requirements, so there are still few buildings that directly apply GFRP curved pan...

AI Technical Summary

Problems solved by technology

However, due to the complex processing methods of traditional GFRP (glass fiber reinforced plastics, commonly known as FRP) panels, many wet operations, poor sanitary conditions, high labor intensity, and low production efficiency, the panel production costs are high and the construction period is long. In addition, for curved surface molds There are certain requirements, so there are still few buildings that directly apply GFRP curved panels in civil engineering, and the building cost is very high
