As we all know, as packaging materials, glass bottles are mainly used for food, oil, wine, beverages, condiments, cosmetic containers and liquid chemical products, etc., with a wide range of uses.
High quality glass bottles also have its shortcomings, such as large weight, high transportation and storage costs, impact resistance, and fragility. Fragility is the biggest problem in the use of glass bottles, which makes glass products subject to great limitations in daily use.
Glass is hard but fragile, has good transparency, high temperature resistance, corrosion resistance and other properties; at the same time, steel is hard and not fragile, and also has the characteristics of high temperature resistance. So people began to think that if they could make a kind of glass that not only has the properties of glass hardness, high temperature resistance, and corrosion resistance, but also has the characteristics of being hard and unbreakable like steel, then this material will be of great use.
The emergence of FRP solved the fragile problem of glass bottles. FRP, namely fiber reinforced plastic, generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics that use glass fiber or its products as reinforcing materials are called glass fiber reinforced plastics.
Due to the different types of resins used, it is called polyester fiberglass, epoxy fiberglass, and phenolic fiberglass. With its light weight and hardness, non-conductive, stable performance, high mechanical strength, less recycling and corrosion resistance, it can replace steel in the manufacturing of machine parts, automobile and ship shells, etc.
