I heard that asbestos is very dangerous. I bought a helmet made of glass fiber reinforced plastic on the Internet. I would like to ask if asbestos and fiberglass are related. Can asbestos material be made into helmets? I'm afraid.
Basically nothing to do with producing FRP helmets without I asbestos material
Asbestos, also known as asbestos, is a commercial term for silicate mineral products with high tensile strength, high flexibility, chemical and thermal resistance, electrical insulation, and spinnability. It is a general term for natural fibrous silicate minerals. Under the jurisdiction of the 2 class a total of 6 kinds of minerals (with serpentine asbestos, amphibole asbestos, asbestos, actinolite anthophyllite tremolite asbestos asbestos, iron, etc.). Asbestos consists of a fiber bundle, consisting of very long, very thin fibers that can be separated from each other. Asbestos is of high fire resistance, electrical insulation and thermal insulation. It is an important fireproof, insulating and heat insulating material.Glass fiber reinforced plastic (FRP), also known as GRP, that is, fiber reinforced plastics, generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics made from glass fiber or its products are referred to as glass fiber reinforced plastics or glass fiber reinforced plastics. Because of the different kinds of resins used, they are called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. Light and hard, non conductive, high mechanical strength, less recycling, corrosion resistance. It can be used instead of steel to make machine parts, automobiles, ship shells, etc..
It has nothing to do with fiberglass.Asbestos is a natural fibrous siliceous minerals generally referred to, is a widely applied in building fire prevention board of silicate mineral fiber, natural mineral fiber is unique, it has good tensile strength and good heat resistance and corrosion resistance, not easy to burn, so it is widely used. There are many kinds of asbestos, the most common three are chrysotile asbestos (Bai Shimian), iron asbestos (brown asbestos) and bluestone (Lan Shimian), of which chrysotile asbestos is the most abundant and the most widely used.Glass fiber reinforced plastic is another name for glass fiber reinforced plastics, commonly known as FRP (Fiber Reinforced Plastics), that is, fiber reinforced composite plastic. Depending on the fiber used, glass fiber reinforced plastics (GFRP), carbon fiber reinforced plastic (CFRP), boron fiber reinforced composite plastics and so on are classified. It is a kind of composite material made of glass fiber and its products (glass cloth, band, felt, yarn, etc.) as reinforcing material and synthetic resin as base material. Fiber reinforced composites are composed of reinforced fibers and matrix. Fiber (or whisker) diameter is very small, generally below 10 mu m, less defects and smaller, fracture strain of about 30/1000, is brittle material, easy to damage, fracture and corrosion. The matrix is much lower in strength and modulus than fiber, but it can withstand large strains, often with viscoelasticity and elasticity, and is a ductile material.
