With the development of 5G, my country’s hair dryer has entered the next generation, and people’s demand for personalized hair dryers is also increasing. Glass fiber reinforced nylon has quietly become the star material of the hair dryer shell and the iconic material of the next generation of high-end hair dryers.
Fiberglass reinforced PA66 is usually used in the mouthpieces of high-quality hair dryers, which can increase the strength and improve the heat capacity. However, with the higher and higher functional requirements of the hair dryer, ABS, which was originally the main material of the shell, was gradually replaced by fiberglass reinforced PA66.
At present, the main factors affecting the preparation of high-performance glass fiber reinforced PA66 composites include the length of the glass fiber, the surface treatment of the glass fiber and its retention length in the matrix.
When fiber is reinforced, the length of the fiber is one of the main factors that determine the fiber-reinforced composite material. In ordinary short fiber reinforced thermoplastics, the fiber length is only (0.2~0.6) mm, so when the material is damaged by force, its strength is basically not used due to the short length of the fiber, and fiber reinforced nylon is used. The purpose is to use the high rigidity and high strength of the fiber to improve the mechanical properties of nylon, so the fiber length has an important role in the mechanical properties of the product. Compared with the short glass fiber reinforced method, the modulus, strength, creep resistance, fatigue resistance, impact resistance, heat resistance and wear resistance of long glass fiber reinforced nylon have been improved, which has broadened its application in automobiles. , electrical appliances, machinery and military applications.
