1. To increase rigidity and hardness, the increase of glass fiber can increase the strength and rigidity of plastics, but the toughness of the same plastic will decrease.
2, to improve heat resistance and heat distortion temperature; nylon, for example, an increase of glass fiber nylon, thermal deformation temperature at least more than doubled, the general glass fiber reinforced nylon temperature can reach 220 degrees or more
3, improve the dimensional stability, reduce the shrinkage rate;
4, reduce the warpage;
5, reduce creep;
6, the flame retardant performance because of the wick effect, will interfere with the flame-retardant system, affecting the flame-retardant effect;
7, reduce the surface gloss;
8, increase moisture absorption;
9. Glass fiber treatment: The length of glass fiber directly affects the brittleness of the material. If the fiberglass is not handled properly, the short fiber will reduce the impact strength and the long fiber treatment will improve the impact strength. To make the brittleness of the material not drop greatly, we must choose a certain length of glass fiber.
Conclusion: In order to obtain good impact strength, the surface treatment of glass fiber and the length of glass fiber are of utmost importance!
