Where are FRP profiles mainly used?

Glass fiber reinforced plastic (FRP), also known as GFRP, is a fiber-reinforced plastic, which generally refers to a matrix of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin. Reinforced plastics with glass fiber or its products as reinforcing materials are called glass fiber reinforced plastics, or glass fiber reinforced plastics, which are different from tempered glass.

Due to the different types of resins used, there are polyester FRP, epoxy FRP, phenolic FRP. Light and hard, non-conductive, stable performance, high mechanical strength, less utilization, corrosion resistance. It can be used instead of steel to make machine parts and shells of automobiles and ships.

The scientific name of FRP is fiber reinforced plastics, commonly known as FRP (fiber reinforced plastics), that is, fiber reinforced composite plastics. According to the different fibers used, it is divided into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, etc. It is a composite material that uses glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as the reinforcing material and synthetic resin as the matrix material.

Fiber-reinforced composites are composed of reinforcing fibers and a matrix. The diameter of the fiber (or whisker) is very small, generally less than 10 m, the defects are few and small, and the breaking strain is about 30 parts per thousand, which is a brittle material, which is easy to be damaged, broken and corroded. Compared with fibers, the strength and modulus of the matrix are much lower, but it can withstand large strain, and often has viscoelastic and elastoplastic, which is a ductile material.

FRP septic tank, FRP integrated sewage treatment equipment, FRP septic tank produced by Yancheng Shenjia Environmental Protection Engineering is used for urban domestic sewage treatment and rural domestic sewage decentralized treatment.

Ousheng pultruded FRP profiles include various sizes of FRP square pipes, FRP round pipes, FRP angle steel, FRP I-beams, FRP channel steel and other standard profiles, as well as various profiles customized according to the needs of customers. FRP profiles are made into products through proper connection and combination, which are widely used in different fields. Such as:

Operating platforms, ladders, guardrails, brackets, equipment, tool handles, insulating supporting components, antenna posts, high-voltage cable trays, aisles, distribution boards and distribution rooms, drainage systems, pressure rods in trains and automobiles, highway guardrails, packing brackets in towers, frame materials, etc.

The strength of Ousheng pultruded FRP profiles is high, very tough and firm, and the ratio of longitudinal bending strength to impact strength has exceeded that of ordinary steel. Its anti-corrosion performance, high temperature resistance, insulation performance is also very good, in the place with corrosive media has a long service life, generally up to more than 20 years, in the industrial and civil and other aspects of the scope of use continues to expand, more and more favored by people.

01 FRP is a fiber-reinforced plastic composed of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. FRP is a glass fiber reinforced material, which is a new type of composite material developed in the early 20th century. It has many advantages such as light weight, high strength, anti-corrosion, heat preservation, insulation, sound insulation, etc., and the early composite material is FRP, in fact, it has nothing to do with the material of steel.

There is no iron in FRP at all, and it is not a composite of glass and steel.

Fiberglass, also known as glass fiber reinforced plastic, refers to the reinforced plastic with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, and glass fiber or its products as reinforcing materials. FRP has the characteristics of light and hard, non-conductive, stable performance, high mechanical strength, less utilization, corrosion resistance, etc., and can replace steel to make machine parts, automobiles, ship shells, etc.

The concept of composite materials refers to the fact that one material cannot meet the requirements of use, and needs to be compounded by two or more materials to form another material that can meet people's requirements, that is, composite materials. For example, a single glass fiber, although the strength is very high, but the fibers are loose, can only withstand tensile force, can not withstand bending, shear and compressive stress, and is not easy to make a fixed geometric shape, is a soft body. If they are bonded together with synthetic resins, they can be made into a variety of rigid products with fixed shapes, which can withstand both tensile stresses and bending, compression, and shear stresses.

This results in a glass-fiber-reinforced plastic matrix composite.

FRP is a composite material that has developed rapidly in the past 50 years. 70% of the production of fiberglass is used to make fiberglass. FRP has a high hardness and is much lighter than steel.

It is used as a fuel tank and pipe in jet aircraft, which can reduce the weight of the aircraft. The astronauts who landed on the moon carried miniature oxygen cylinders on their backs were also made of fiberglass. FRP is easy to process, stainless and rotten, and does not need to be painted.

China has widely used FRP to manufacture various small motorboats, lifeboats, yachts, and automobile manufacturing, saving a lot of steel.

1. Glass fiber reinforced plastic (FRP), also known as GFRP, is a kind of fiber reinforced plastic, which generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastic made of glass fiber or its products as a reinforcing material is called glass fiber reinforced plastic, or glass fiber, which is different from tempered glass.

2. Classification: According to the fibers used, it can be divided into glass fiber reinforced composites (GFRP), carbon fiber reinforced composites (CFRP) and boron reinforced composites. It is a composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as the reinforcing material and synthetic resin as the matrix material.

Fiber-reinforced composites consist of reinforcing fibers and a matrix. The diameter of the fibers (or whiskers) is very small, generally less than 10 m, the defects are getting smaller and smaller, and the strain at break is about 30%. It is a fragile material that is prone to damage, breakage, and corrosion.

The strength and modulus of the matrix are much lower than that of fibers, but it can withstand large strains, is often viscoelastic and elastoplastic, and is a ductile material.

3. Performance: glass has high hardness, but fragile performance, good transparency, high temperature resistance, corrosion resistance, etc.; At the same time, steel is very hard, not easy to break, and has the characteristics of high temperature resistance.

What is FRP.

FRP products refer to the finished products processed from resin and glass fiber as raw materials, FRP products mainly include FRP storage tanks, FRP mixing tanks, FRP cooling towers, FRP water tanks, FRP tables and chairs, FRP pipes, FRP trash cans. The scientific name of FRP is glass fiber reinforced plastic, commonly known as FRP. It is a new type of composite material developed in the early 20th century, which has many advantages such as light weight, high strength, anti-corrosion, heat preservation, insulation, sound insulation and so on.

Because its strength is equivalent to steel, and it contains glass components, it also has the color, shape, corrosion resistance, electrical insulation, heat insulation and other properties of glass.

The origin of FRP.

The traditional glass texture is hard and easy to break, with good transparency and anti-corrosion effect; The steel material is hard enough not to be chipped, and it is also very resistant to high temperatures, but it does not have good permeability. After countless repeated experiments and researches, smart people finally made FRP with high temperature resistance, corrosion resistance, and unbreakable characteristics that are not weaker than steel materials.

Features of FRP.

FRP combines the advantages of traditional glass and steel, its weight is very light, the relative density is between, only 1 4-1 5 of carbon steel, but its tensile strength is close to carbon steel, or even more than carbon steel. It also has very light corrosion resistance, and has good resistance to the atmosphere, water and general concentrations of acids, alkalis, salts, as well as a variety of oils and solvents. In addition, FRP also has excellent characteristics such as good insulation and designability.

The role of FRP.

FRP has the characteristics of bizarre shape, customizable, and random color allocation, which are favored by various merchants and sellers. Railway industry, shipbuilding industry, electrical industry and communication engineering and other industries. The main FRP products used in these industries are cooling towers, corrosion-resistant pipes, materials and components for automobile manufacturing, train windows, supporting parts for large steel boats, cable protection pipes, etc.

What is FRP. I believe that after reading the article, I have a certain understanding of FRP. FRP is not only light and strong, but also corrosion-resistant, whether it is moisture, or acid and alkali, it is difficult to erode it.

In terms of technology, the use of FRP is also very extensive, and its designability is also very outstanding. FRP products have gradually become familiar in our lives, and it replaces the use of some metal and plastic materials in our lives. The introduction is over, I hope it can help everyone.

FRP (fiber reinforced plastic), alias: glass fiber reinforced composite plastic, is based on glass fiber reinforcing agent and unsaturated polyester, epoxy resin and phenolic resin adhesive.

Due to the different types of resins used, it is known as polyester FRP, epoxy FRP and phenolic FRP.

The scientific name of FRP is glass fiber reinforced plastic (FRP, also known as GRP). It is a typical composite material. In the process of making FRP, with various resins as the matrix, the glass is drawn into very fine filaments and woven into products.

Glass is a material with low strength and easy brittleness, but after the glass is melted and drawn into a very fine glass fiber filament, its properties will change, and this glass fiber filament is very fine and has high strength, and can even be woven into cloth.

FRP concentrates the characteristics of glass fiber and synthetic resin, and has the characteristics of light weight, high strength, chemical corrosion resistance, heat resistance, good electrical insulation, and instantaneous high temperature ablation resistance.

Fiberglass resin composites.

This is a composite material. The full name is glass fiber reinforced plastic, which is a composite material with glass fiber as aggregate and epoxy resin or phenolic resin as filler. The resin is also the adhesive.

Let's take a look at a few legends

What material does FRP belong to? What is the difference between FRP and tempered glass? What are the types of glass materials? As a non-expert, you may not know much about this. But don't worry, I'll give you a brief introduction to these questions.

It is a kind of composite material, because of its unique properties, it has been widely used in more than 10 industries such as aviation, railway, construction, furniture, building materials, sports and sanitation engineering, and has been highly praised and has become the darling of demand in the material industry. FRP is still different from traditional products, especially in terms of performance, use and life, which are far beyond traditional products.

What is the difference between FRP and tempered glass?

Tempered glass is a kind of safety glass, which can also be regarded as an upgraded version of glass, and also has the characteristics of general glass, such as impact resistance and bending strength, and small particles of fragments. FRP, which is a type of composite material, can be reprocessed, while tempered glass cannot be reprocessed.

Carbon fiber is one of the composite materials, but it is more expensive than glass. Carbon fiber, is a new belt of reinforcing materials, compared with FRP, its weight is lighter, the strength is greater, and the toughness is higher, especially its deformation resistance, is three times that of FRP, and the most important thing is that the corrosion resistance is more prominent. In addition, it is similar on the surface, so some products on the market are made of FRP.

FRP has the advantages of sun protection and strong quality, and the products produced have a bright appearance and are easy to process, so they are well recognized by consumers. According to statistics: after more than 40 years of development in China, there are now more than 40,000 kinds of FRP products that have been developed, and have been widely used in various fields, and play an important role in the economy.

Summary: After reading the above introduction, I believe you have a further understanding of what material FRP belongs to. If you need to know more about it, please continue to ******, and more exciting content will be presented to you in the future.
