We can see all kinds of sculptures everywhere in our lives. Among them, glass fiber reinforced plastic sculpture is a relatively common one. For glass fiber reinforced plastic sculpture, people may still have a little understanding of it. Let me introduce you to the characteristics and production process of glass fiber reinforced plastic sculpture. 1. The characteristics of glass fiber reinforced plastic sculpture 1. Lightweight and high-strength relative density is between 1.5~2.0, only 14~15 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, and the specific strength can be comparable to that of high-grade alloy steel. Compared with. Therefore, it has excellent results in aviation, rockets, space vehicles, high-pressure vessels and other products that need to reduce its own weight. 2. Its corrosion resistance is good for atmospheric, water and general concentrations of acids and alkalis. , Salt, and a variety of oils and solvents have good resistance. It has been applied to all aspects of chemical anti-corrosion, and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc. 3. It has good electrical properties and excellent insulation Material, used to make insulators. It can still protect good dielectric properties at high frequencies. Microwave permeability is good and has been widely used in radar radomes. 4. It has good designability and can be flexibly designed according to needs. Structural products, to meet the requirements of use, can make the product have a good integrity. Second, the production process of glass fiber reinforced plastic sculpture 1. Design and modeling of the model glass fiber reinforced plastic sculpture design should consider the characteristics of the material process. The glass fiber reinforced plastic is easy to form beautiful streamlined products and highlight the work A sense of the times, the arc streamline can be used in the design. Due to the light weight and high strength of FRP, it can produce works with strong dynamic and small supporting area. Sometimes it is necessary to post-paint the surface layer, and the gel coat has leveling properties, and there is a certain degree of tension under the effect of tension during curing. The flattening effect of FRP is not suitable for expressing fine texture. These should be carefully considered when designing. The original model can be made of clay, and after the sculpture is completed, it can be dried naturally, and then the FRP mold can be made. 2. The production of FRP adopts the hand lay-up method. According to the shape and characteristics of the sculpture, from the perspective of facilitating molding and demolding, the mold is decomposed into several units to be reproduced. According to this, they are formed and combined into a whole. Then the overall treatment and painting, a glass fiber reinforced plastic sculpture work It is completed. 3. Mold making. Mold making is the key to molding. Mold making is often made of gypsum, but gypsum has low strength and is easy to deform after a long time. Silicone rubber and glass fiber reinforced plastic materials can be used to make molds. Silicone rubber is in a fluid state before use , Good flow and filling. After cross-linking reaction, an elastomer is formed, which has greater elastic deformation. The water of the original mold has no effect on the cross-linking reaction. After cross-linking, the silicone rubber has good sealing performance and does not adhere to the original glass fiber reinforced plastic. The surface layer of the glass fiber reinforced plastic mold can replicate the shape of the work with high quality and can be smoothly demolded. However, the cross-linked body is easy to deform and needs to support the carrier. Use the characteristics of easy forming of glass fiber reinforced plastic as the carrier of the mold. The above content is the Beijing sculpture manufacturer I bring you an introduction about the characteristics and production process of glass fiber reinforced plastic sculpture, I hope it can help you.
