What are the advantages of flat fiberglass sheets?
(1) Lightweight and high strength: The relative density of flat fiberglass sheets is between 1.5-2.0, which is only 1/4-1/5 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, and the specific strength is comparable to that of high-grade alloys. Compared to steel. Therefore, it has excellent results in aviation, rockets, space vehicles, high-pressure vessels, and other products that need to reduce their own weight. For example, the tensile, flexural and compressive strengths of certain epoxy-based FRP can reach more than 400Mpa.
(2) Good corrosion resistance: FRP is a good corrosion-resistant material, and it has good resistance to atmosphere, water and general concentrations of acids, alkalis, salts, and a variety of oils and solvents. It has been applied to all aspects of chemical corrosion protection, and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.
(3) Good electrical properties: flat fiberglass sheets are excellent insulating materials used to make insulators. It can still protect good dielectric properties under high frequency. It has good microwave permeability and has been widely used in radomes.
(4) Good thermal performance: FRP has low thermal conductivity, 1.25-1.67kJ/(m•h•K) at room temperature, only 1/100-1/1000 of metal, and is an excellent thermal insulation material. It is an ideal thermal protection and ablation resistant material under transient ultra-high temperature conditions.
(5) Good designability and manufacturability
① Various structural products can be flexibly designed according to needs to meet the requirements of use, and the products can have a good integrity.
②The forming process of the glass fiber reinforced plastic plate can be flexibly selected according to the shape, technical requirements, use and quantity of the product.
