1. Enhance rigidity and hardness. The increase of glass fiber can increase the strength and rigidity of plastic, but the toughness of the same plastic will decrease. Example: Flexural modulus;
2. Improve heat resistance and heat distortion temperature. Taking nylon as an example, glass fiber nylon is added. The heat distortion temperature is increased by at least two times. The temperature resistance of general glass fiber reinforced nylon can reach 220 degrees or more.
3. Improve dimensional stability and reduce shrinkage;
4. Reduce warpage and deformation;
5. Reduce creep;
6. Due to the candle wick effect, the flame retardant performance will interfere with the flame retardant system and affect the flame retardant effect;
7. Reduce the gloss of the surface;
8. Increase hygroscopicity;
9. Glass fiber treatment: The length of the glass fiber directly affects the brittleness of the material. If the glass fiber is not handled well, the short fiber will reduce the impact strength, and the long fiber will increase the impact strength. To make the brittleness of the material not drop too much, it is necessary to choose a certain length of glass fiber.
