Fiberglass is a kind of inorganic non-metallic material with excellent performance, which has many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. Glass fiber is a very good substitute material for metal materials. With the rapid development of market economy, glass fiber has become an essential raw material for construction, transportation, electronics, electricity, chemical industry, metallurgy, environmental protection, national defense and other industries. Because it is widely used in many fields, people pay more and more attention to glass fiber. Because waterjet cutting is a non-contact cold working process, coking and hot cracking will not occur in the processing. The section is smoother, brighter and cleaner, and the size is accurate. Therefore, waterjet cutting technology is a good choice for cutting glass fiber materials.
