Glass fiber function

1. Enhance the rigidity and hardness. The increase of glass fiber can improve the strength and rigidity of plastics, but the toughness of the same plastics will decrease. Example: bending modulus;
2. Improve the heat resistance and thermal deformation temperature. Take nylon as an example, the thermal deformation temperature of glass fiber reinforced nylon is increased by at least twice. The temperature resistance of general glass fiber reinforced nylon can reach above 220 degrees
3. Improve dimensional stability and reduce shrinkage;
4. Reduce warping deformation;
5. Reduce creep;
6. Because of the candle wick effect, it will interfere with the flame retardant system and affect the flame retardant effect;
7. Reduce the surface glossiness;
8. Increase moisture absorption;
9. Glass fiber treatment: the length of glass fiber directly affects the brittleness of materials. If the glass fiber is not well treated, the short fiber will reduce the impact strength, and the long fiber will improve the impact strength. In order to prevent the brittleness of the material from decreasing greatly, a certain length of glass fiber should be selected.
