Problems solved by technology

[0004] The problem with the above-mentioned manufacturing method is that a large number of forming molds need to be disassembled when forming FRP, and a large number of auxiliary structures such as ribs and plates need to be installed on the structure of FRP products to ensure strength and rigidity.
The manufacturing cost of FRP with this structure is high, the number of molds is large, and the production cycle is long.

Embodiment 1

[0025] In this embodiment, the foam material is cut into the required foam core material 1 according to the drawing, and the glass fiber cloth 2 is wound on the foam core material 1; FRP resin3. At room temperature, 70% by weight of epoxy resin, 2% by weight of ethylenediamine, 10% by weight of talcum powder, and 8% by weight of quartz sand are uniformly blended into FRP resin 3 with fillers. Use positioning nails, jigs, and templates for positioning. According to the shape and structure requirements of FRP products, a FRP blank 4 is built; after the naturally dried FRP component blank is polished and modified, it is assembled into a whole blank 5 by multiple pieces; the surface of the whole blank 5 is then pasted with FRP resin and glass cloth. 6. After drying and polishing, the required FRP hull parts will be finished. The technology of the invention can be widely used in the manufacture of glass-steel structure boats, glass-steel models, sculptures, brackets and glass-ste...

Embodiment 2

[0028] The present invention takes the foam material and cuts it into the required foam core material 1 according to the drawings. Epoxy resin 3 with fillers was uniformly blended with 72% by weight of epoxy resin, 18% by weight of ethylenediamine, and 10% by weight of quartz sand. A glass mat 2 is wound on a foam core material 1, and then epoxy resin 3 with a filler is coated on the bonding surfaces of the foam core materials wound around a plurality of glass fiber mats. Use positioning nails 4, fixtures, and pattern positioning to build a glass fiber reinforced plastic wall blank; the surface of the naturally dry wall blank is then pasted with glass fiber reinforced plastic resin, and glass cloth 5 is pasted. After drying, it is polished and modified to form the required glass fiber reinforced plastic wall. finished product. The technology of the invention can be widely used in the manufacture of glass-steel structure boats, glass-steel models, sculptures, brackets and glas...

Abstract

The invention is a method of making glass fibre reinforced plastic structure by build-forming, mainly winding glass fiber material on the foam core material, coating glass fibre reinforced plastic resin with fillings on the combination surfaces of many foam core material with glass fibers, adopting locating nail, clamp, and master form, etc, to locate, building into component blanks, and polishing the dried blanks and then splicing many blanks into a whole blank, again coating the glass fibre reinforced plastic resin on the surface of the whole blank, and pasting on glass cloth, drying and then polishing so as to obtain the finished products. It has simple making technique, and convenient to construct; can largely reduce cost and shorten production cycle, and has high specific strength of the whole structure; can act as both mould and material; reduces making cost of glass fibre reinforced plastic products. It simplifies producing technique, can produce large-scale glass fibre reinforced plastic products, and can implement field design and construction, etc.

Description

Technical field: [0001] The invention relates to a method for manufacturing a glass-steel structure formed by masonry, and belongs to the technical field of glass-steel materials. Background technique: [0002] Before the present invention was made, adopting FRP material to manufacture various FRP products has been widely used in many industries. FRP structural materials, the processing technology is as follows: [0003] The manufacture of FRP products generally adopts disassembled molds and hand-pasted molding. First use wood and gypsum to make a model of the product, and then use resin, glass fiber reinforced plastic and other materials to paste and polish the mold according to the model. Then repeatedly paint resin, paste glass fiber cloth and felt on the forming mold by hand, and after reaching the specified number of layers, dry and polish to make multi-layer FRP products. [0004] The problem of adopting the above-mentioned manufacturing method is that a large numbe...
