The profile products of FRP materials made by pultrusion and molding or hand lay-up are collectively referred to as FRP profiles. The more common round pipes, square pipes, angle steels, channel steels and other products on the market are all types of profiles. The following editor is mainly about the knowledge of the structural characteristics of FRP profiles.
FRP profiles are used more in our lives, and perhaps everyone is familiar with them. FRP profiles have many special advantages in use, so they are also very popular.
1. The structural characteristics of FRP profiles mainly include the following aspects:
1. Thin, long, small
It is called profile because these products are in line with the structural characteristics of the slender profile.
2. Often used as an accessory
For example, the products used in the FRP guardrail project are mainly pipe fittings and pillars. Pipe fittings include commonly used pipes, square pipes, and support parts including bases, tees, crosses and other products.
3. Good toughness and high strength
The raw materials are mainly resin and glass fiber, which are fully combined by pultrusion, molding or hand lay-up. Give the product sufficient strength and compressibility.
4. Various models
Compared with the molding and hand lay-up manufacturing process, the main production process of FRP profiles is pultrusion, and the main production method is based on pultrusion equipment. The product mold is replaced to achieve a variety of production purposes.
5. Strong designability
The mold can be customized according to specific drawings or samples, with strong plasticity.
2. Unique manufacturing of FRP profiles:
Ordinary glass fiber reinforced plastic profiles are made of natural resin with glass fiber felt on the delicate glass fiber bag. In addition, the fine fiber core layer should be a glass fiber reinforced plastic profile, which has the advantage of being strong and tough.
In addition, the full value of longitudinal buckling strength and impact strength has exceeded that of ordinary steel. Coupled with the use of glass fiber mat to improve the transverse strength of steel, it forms a rich natural resin layer in appearance, with satisfactory anti-corrosion and anti-cracking properties.
Generally, FRP profiles are reinforced materials such as glass fiber non-twisted coarse cloth, glass fiber, and felt skin that are fully soaked in natural resin mixture, and are heated and solidified in the mold steel after forming the production model.
Then, under the effect of the tension of the drag mechanism, the drawn infinite length profiles are successively drawn. In addition, pultruded profiles can be long and preset, and different styles of pultruded profiles can be combined with appropriate signatures to produce a variety of FRP profile products.
The above is the introduction to the structural characteristics of FRP profiles. After the corresponding understanding, everyone has a new understanding of FRP profiles. Because of its good performance, it has been unanimously recognized by people, and it is used more and more. However, you should do some simple understanding before buying, because only a good FRP profile can achieve the expected use effect.
