The definition of FRP sculpture is a new type of handicraft sculpture that came into being. As the city develops, the use of FRP urban sculpture is increasingly widespread.
Shape color: FRP sculpture is rich and colorful, and the flexibility is stronger.
Material: FRP sculpture is light in weight and easy to handle.
FRP sculpture definition: similar to the composition of reinforced concrete, the glass is melted and pulled into fiberglass that is only a fraction of a tenth of the diameter of the hair. The original hard and brittle glass becomes soft and soft. Tenon-resistant Fiberglass can increase the tensile strength by a factor of ten.
Using Fiberglass as the bone and bone, using synthetic resin (phenolic plastic, epoxy resin, and polyester resin) as the muscle, let them be integrated into one, the material made, the tensile strength can be comparable with steel – hence the name is FRP.
Here we have to distinguish between resin sculpture and Fiberglass sculpture:
Resin Sculpture: Sculpture Fiberglass reinforced plastic sculpture with resin alone: resin plus Fiberglass yarn (cloth) composite sculpture Fiberglass reinforced plastic is also called unsaturated resin
FRP sculptures are widely used because of their relatively low cost and excellent performance.
It is widely used in squares, hotels, real estate, parks, homes, campuses, shopping malls, etc.
Characteristics of FRP: FRP sculpture is a composite material composed of synthetic resin as the basic material and Fiberglass and its products as reinforcing materials.
FRP sculpture is a finished type of sculpture with lightweight, corrosion resistance, and relatively low cost. Also known as FRP, the scientific name fiber reinforced plastic, the domestic custom is called Fiberglass.
The advantages of FRP sculpture: strong plasticity, lightweight, and high strength, the density is only 1.5~2.0, only 1/4~1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be combined with high-grade alloy. Compared to steel. (As long as you want to get the shape, FRP can make the finished product), relatively easy to form, lightweight, high strength, and relatively low cost, surface effects and so on.
Good corrosion resistance, good corrosion resistance, good resistance to atmospheric, water and general concentrations of acids, bases, salts and a variety of oils and solvents.
FRP sculpture can achieve a variety of effects, such as conventional color (PANTONG color), painted, gold, silver, gold platinum, silver platinum, ancient silver, bronze, red copper and so on. It has strong corrosion resistance and has a certain resistance to the atmosphere and water. Has a strong thermal performance: it is a good insulating material, it is safe to use, and it has a certain thermal protection and ablation resistance at a certain high temperature, which can achieve good results.
With good design performance, according to the improvement of the current technical level, the different design concepts, combined with the flexible characteristics of the FRP sculpture, the random design of various structural sculptures, so that this sculpture art appears more meaningful value. Coupled with the proficiency of the current production process, the perfection of the carving art and the improvement of the level, it is enough to show the existence value of the FRP sculpture. The process is excellent, and the molding process can be flexibly selected according to the shape, technical requirements, use and quantity of the product.
The economic effect is outstanding, the process is simple, and it can be formed at one time, especially for a product with a complicated shape and a small amount of molding, and the process superiority is further emphasized. Good electrical properties (independent of FRP), is an excellent insulating material used to make insulators. Good dielectric properties are still protected at high frequencies.
It has good microwave permeability and has been widely used in radomes.
Disadvantages of FRP sculpture: aging phenomenon, aging phenomenon is a common defect of plastic, its own FRP is a kind of less elastic material, long-term use, there will be some temperature resistance drop, easy to bake flowers, especially in the outdoors, for a long time Ultraviolet rays, sand, rain, snow, chemical media, mechanical stress, etc. are likely to cause performance degradation.
The long-term temperature resistance is poor. Generally, FRP cannot be used for a long time under high temperature. The strength of general-purpose polyester FRP is obviously lower than 50 °C, and it is generally only used below 100 °C. The general-purpose epoxy FRP has a significant decrease in strength above 60 °C.
However, it is possible to select a high-temperature resistant resin so that a long-term operating temperature of 200 to 300 ° C is possible. It can also cause some damage at the same low temperature.
The modulus of elasticity is low, and the modulus of elasticity of FRP is twice as large as that of wood, but 10 times smaller than that of steel (E = 2.1 × 106). Therefore, it is often insufficient in rigidity and easily deformed in the product structure. It can be made into a thin shell structure, a sandwich structure, or it can be compensated by high modulus fibers or reinforcing ribs. The interlaminar shear strength is low, and the interlaminar shear strength is borne by the resin, so it is very low. The adhesion between layers can be improved by selecting a process, using a coupling agent, etc., and most importantly, avoiding shearing between layers during product design.
Therefore, the FRP sculpture is not easy to set up and accept the influence of the natural environment for a long time. It should be suitable for a certain environment, and at the same time, pay attention to maintenance.
Summary: In summary, the Beijing sculpture company Boao sculpture suggests to use FRP sculpture indoors as much as possible, and choose a professional sculpture processing factory to make FRP, which has better durability; if you must choose outdoor, it is recommended that the temperature difference between the four seasons is too large. If the city chooses carefully, it must pay attention to regular maintenance and other measures (choose professional sculpture companies).
The design of FRP sculpture should consider the material process characteristics. FRP is easy to form beautiful streamlined products, highlighting the contemporary sense of the work, and can be designed with a circular streamline. FRP is light and high-strength, and it can produce works with a small dynamic support area.
Sometimes it is necessary to apply the surface layer afterward, and the gel coat has a leveling property, and has a certain leveling effect under the action of tension during curing, and is not suitable for expressing fine texture. These should be carefully considered when designing. The Fiberglass reinforced plastic sculpture product is colored. This process is very technically demanding for the hand-painted and the paint master. If the color is not well colored, the quality of the product will be lowered. After the color is good, the customer should look at the color coloring effect to avoid waste. A lot of labor has also delayed the delivery time of customers.
