Glass bottles, as packaging materials, are mainly used in food, oil, alcohol, beverages, seasonings, cosmetics, and liquid chemical products, and are widely used. The main characteristics of glass bottles are: non-toxic and odorless; Transparent, aesthetically pleasing, with good barrier properties, breathable, and abundant raw materials, glass bottles are inexpensive and can be reused multiple times. Glass bottles have the advantages of heat resistance, pressure resistance, and cleaning resistance, which can be sterilized at high temperatures or stored at low temperatures. The main raw materials for glass bottles are natural ore, quartz, caustic soda, limestone, etc. Glass bottles have a high degree of transparency and corrosion resistance, and will not undergo changes in material properties when in contact with most chemicals.

But glass bottles also have their drawbacks, such as high weight, high transportation and storage costs, poor impact resistance, and fragility. Fragility is the biggest problem with glass bottles in use, which limits the daily use of glass products. So, how to solve the problem of glass bottles being fragile?

The emergence of fiberglass has solved the problem of glass being fragile. Fiberglass reinforced plastic, also known as fiber reinforced plastic, generally refers to the use of glass fiber to reinforce unsaturated polyester, epoxy resin, and phenolic resin matrices. Reinforced plastics using glass fiber or its products as reinforcing materials are called glass fiber reinforced plastics, or fiberglass reinforced plastics. Due to the different types of resins used, they are referred to as polyester fiberglass, epoxy fiberglass, and phenolic fiberglass. Lightweight and hard, non conductive, stable performance, high mechanical strength, less recycling, and corrosion resistance. It can replace steel in manufacturing machine parts, automobiles, ship shells, etc.

Glass is hard but fragile, with good transparency, high temperature resistance, corrosion resistance, and other properties; At the same time, steel is very hard and not fragile, and also has the characteristics of high temperature resistance. If a material can be manufactured that has the hardness, high temperature resistance, and corrosion resistance of glass, as well as the hardness and non shattering properties of steel, it will definitely have great applications.
