1: Chemical corrosion resistance of SMC insulation board: fiber reinforced polyester material has good corrosion resistance characteristics, such as acid, dilute alkali, salt, acid, dilute alkali, salt, organic solvent and seawater, while metal material is not resistant to acid and seawater.
2: Lightweight and high strength: specific strength and specific modulus are one of the indicators to measure the bearing capacity of materials,. The specific modulus of fiber reinforced polyester material is equal to that of steel, but its specific strength can reach 4 times that of steel.
3: Good electrical properties: This material not only has excellent electrical insulation properties, but also maintains good dielectric properties at high frequencies, is not affected by electromagnetic waves, and does not reflect electromagnetic waves. These properties are far beyond the comparability of metal materials
4: Notch sensitivity: When the components are overloaded and a small number of fibers are broken, the load is rapidly distributed on the undamaged fibers, so as to achieve mechanical balance again, which is unmatched by metal components.
5. Good fatigue resistance: the tensile strength of fiber reinforced polyester material is slightly better than that of steel. The fatigue resistance limit of steel and most metal materials is 40% - 50% of their tensile strength, while the tensile strength of fiber reinforced composites is generally higher than this value, and the z height can reach 70% - 80%.
6. Low thermal conductivity and low expansion coefficient: when there is temperature difference, the thermal stress generated is much smaller than that of metal.
7. Flame retardant, smokeless and non-toxic: this material is a flame retardant material with a flame retardant grade of FV0, smoke intensity of 15 under high temperature combustion, non-toxic smoke, and ZA1 toxicity level.
8. Long service life: it has been proved that its service life is at least 20 years; The simulated aging test shows that its service life is more than 20 years, far exceeding that of traditional materials such as metals.
