Physical properties of FRP tanks
Good designAccording to the needs, flexible design of various structural products can be used to meet the use requirements, and the products can be well integrated.Material can be fully selected to meet the performance of products, such as: can design corrosion resistance, high temperature resistance, the product has a particular direction of high strength, good dielectric properties, and so on.
Good thermal performanceFRP has a low thermal conductivity and is 1.25~1.67kJ/ (M. H. K) at room temperature. Only metal 1/100~1/1000 is a good thermal insulating material. It is an ideal thermal protection and ablative material in the instantaneous ultra high temperature, which can protect the spacecraft from the erosion of high velocity air at temperatures above 2000 degrees celsius.
Good electrical performanceIt is a good insulating material used for making insulators. High dielectric protection can be maintained at high frequencies. Microwave permeability is good, and has been widely used in radome.
Good corrosion resistanceFRP is a good corrosion resistant material. It has more resistance to atmosphere, water and acid, alkali, salt, and various kinds of oils and solvents. Has been applied to all aspects of chemical corrosion, is replacing carbon steel, stainless steel, wood, nonferrous metals and so on.
Light high-strengthThe relative density is between 1.5~2.0 and only 1/4~1/5 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, while the specific strength can be compared with that of advanced alloy steel. As a result, aviation, rockets, aerospace vehicles, high pressure vessels, and other applications that need to reduce weight have excellent results. The tensile, flexural and compressive strengths of some epoxy FRP can reach over 400Mpa.
