Fiberglass Rod

There are many types of fiberglass rods, and the application scenarios and performance of each fiberglass rod are very different. Most of the glass fiber rods on the market are without any special reinforcement materials. This type of glass fiber rod can only meet some applications. The fiberglass rods produced by our factory cover most of the general types of fiberglass rods. Below I will introduce the difference between each type of fiberglass rod, and you will find the fiberglass rod you need here.

How are fiberglass rods made?

Fiberglass rod is made of fiberglass yarn and resin by mold heating and curing. At present, the main production process of fiberglass rod is pultrusion. The worker first calculates the number of yarn required according to the size of fiberglass rod, and then passes a fixed number of yarn through the forming mold Before passing through the mold, the yarn should be contaminated with a certain amount of resin. When the resin is brought into the mold, the resin solidifies due to the high temperature of the mold, thus forming the fiberglass yarn into fiberglass rod.

What size of fiberglass rod can we make

The length of the fiberglass rod is not limited, we even can make a rod with length more than 1000 meters, if the out diameter you need is not in the below list, please contact us directly !

Several factors affecting the performance of glass fiber rods

Raw materials

Fiberglass Yarn

There are two kinds of glass fiber yarns that we often use, E-glass ( alkali-free ) and C-glass ( medium-alkali ). The strength of E-glass products is about 10-20% higher than that of C-glass products.

Resin

There are roughly 4 types of commonly used resins, unsaturated resins, vinyl resins, polyurethane resins, and epoxy resins. The strength of the glass fiber rods made from these resins ranges from low to high.

In addition, according to clients requirements we will using different fillers during production, such as flame retardant, UV resistant, fluorescent, etc.

Features of fiberglass rod

Light weight and high strength

The relative density is around 1.9, only 1 / 4 ~ 1 / 5 of carbon steel, but the tensile strength is close to or even better, and the specific strength can be compared with high-grade alloy steel. Therefore, it has excellent effect in the application of aviation, rocket, spacecraft, high pressure vessel and other products that need to reduce self weight. The tensile, flexural and compressive strength of some epoxy FRP can reach more than 400MPa.

Good corrosion resistance

FRP is a good corrosion-resistant material, which has good resistance to atmosphere, water, general concentration of acid, alkali, salt, a variety of oils and solvents. It has been applied to all aspects of chemical anti-corrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.

Good electrical performance

It is an excellent insulating material, used to make insulators. Good dielectric property can be protected at high frequency. Microwave transmission is good and has been widely used in radome.

Good thermal performance

The thermal conductivity of FRP is low, which is 1.25 ~ 1.67kj / (m · h · K) at room temperature, only 1 / 100 ~ 1 / 1000 of metal, so it is an excellent thermal insulation material. In the case of instantaneous ultra-high temperature, it is an ideal thermal protection and ablation resistant material, which can protect the spacecraft from the erosion of high-speed airflow above 2000 ℃.

Good designability

According to the needs, we can flexibly design a variety of structural products to meet the use requirements, which can make the product have a good integrity.
Materials can be fully selected to meet the performance of the product, such as: can be designed to resist corrosion, transient high temperature, products in a certain direction have special high strength, good dielectric, and so on.

Excellent technology

The molding process can be flexibly selected according to the shape, technical requirements, usage and quantity of the product.
The process is simple, can be formed at one time, the economic effect is outstanding, especially for the complex shape, not easy to form a small number of products, more prominent its technological superiority.

Application of fiberglass rod

Because of its unique performance advantages, fiberglass rods have been widely used in more than ten industries, such as aerospace, railway, decorative architecture, home furniture, advertising display, craft gifts, building materials and sanitary ware, yacht berthing, sports materials, environmental sanitation engineering and so on, and are highly praised. They have become the demand pet of businessmen in the material industry in the new era. FRP products are also different from traditional materials, and are much better than traditional products in performance, use and life. It is easy to shape, can be customized, color deployment at will, favored by businesses and sellers, occupies an increasing market share, broad prospects!
