- 1. ABS engineering plastic, also known as PC+ABS (Engineering Plastic Alloy) in the chemical industry, is called plastic alloy in Chinese. The reason why it is named PC+ABS is that this material not only has the excellent heat and weather resistance, dimensional stability, and impact resistance of PC resin, but also has the excellent processing flowability of ABS resin. So when applied to thin-walled and complex shaped products, it can maintain its excellent performance and the formability of plastic and a material composed of esters.
2. Fiberglass reinforced plastic (FRP), also known as glass fiber reinforced material, is a new type of composite material developed abroad in the early 20th century. It has many advantages such as light weight, high strength, corrosion resistance, insulation, sound insulation, etc. The earliest composite material to appear was fiberglass, which has nothing to do with steel. Fiberglass does not contain iron at all and is not a composite of glass and steel. In fact, fiberglass is a material composed of glass fiber and one or more thermosetting or thermoplastic resins, such as phenolic resin, epoxy resin, polyester resin, polyimide resin, etc.
3. Carbon fiber is a fibrous carbon material. It is a new type of material with higher strength than steel, lower density than aluminum, better corrosion resistance than stainless steel, higher temperature resistance than heat-resistant steel, and the ability to conduct electricity like copper. It has many valuable electrical, thermal, and mechanical properties. Aircraft made of composite materials made of carbon fiber and plastic are not only lightweight, but also consume less power, have greater thrust, and produce less noise; Using carbon fiber to make electronic computer disks can increase the storage capacity and computing speed of the computer; Using carbon fiber reinforced plastic to manufacture spacecraft such as satellites and rockets has high mechanical strength, low mass, and can save a lot of fuel.
