Какъв материал са пръти от фибростъкло, използвани за индукционни пещи за топене?

The glass fiber rod for induction melting furnace is a composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as the reinforcing material and synthetic resin as the matrix material. The concept of composite material means that a material cannot meet the requirements of use, and it needs to be compounded by two or more materials to form another material that can meet people’s requirements, that is, composite materials. A single type of glass fiber has high strength, but the fibers are loose and can only withstand tensile force, not bending, shearing and compressive stress, and it is not easy to make a fixed geometric shape. If they are bonded together with synthetic resin, they can be made into various rigid products with fixed shapes, which can withstand not only tensile stress, but also bending, compressive and shear stress. This constitutes a glass fiber reinforced plastic matrix composite.
