FRP (also known as glass fibre reinforced plastic, internationally recognised by the abbreviation GFRP or FRP) is a variety of composite materials with a wide range of properties and uses. It is a new functional material made from synthetic resin and glass fibre through a composite process.

Advantages of FRP

(1) FRP is light and strong

The relative density is between 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 compared with that of senior alloy steel. As a result, it is highly effective in aerospace, rockets, spacecraft, high pressure vessels and other applications where weight reduction is required. The tensile, flexural and compressive strengths of some epoxy FRPs can reach over 400Mpa.

(2) Good corrosion resistance of FRP

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

(3) Glass fiber reinforced plastic (FRP) good electrical properties

Is an excellent insulating material, used to manufacture insulators. Good dielectric properties can still be protected under high frequency. Microwave permeability is good, has been widely used in radar radome.

(4)FRP has good thermal performance

FRP thermal conductivity is low, 1.25~1.67kJ/(m-h-K) at room temperature, only 1/100~1/1000 of metal, is an excellent thermal insulation material. In the case of transient ultra-high temperature, it is the ideal thermal protection and ablation-resistant material, and can protect the cosmic craft to withstand the rush of high-speed airflow above 2000ºC.

(5)Good designability of FRP

It is possible to design various structural products flexibly to meet the requirements of use according to the needs, which can make the products have good integrity.

You can fully select materials to meet the performance of the products, such as: you can design corrosion-resistant, instantaneous high temperature resistant, products with special high strength in a certain direction, good dielectric properties, etc.

Since FRP products can be designed and compounded according to different usage environments and special performance requirements, they can basically meet the performance requirements of different applications for the use of products as long as suitable raw material varieties are selected. Therefore, FRP material is a designable material variety.
