1. Enhance rigidity and hardness. Increased glass fiber can increase the strength and rigidity of the plastic, but the toughness of the same plastic will decrease. Example: bending modulus;
2. Improve heat resistance and thermal deformation temperature. Taking nylon as an example, the nylon of the glass fiber is increased. The thermal deformation temperature is at least doubled.
3. Improve size stability and reduce shrinkage;
4. Reduce warp and deformation;
5. Reduce creep;
6. For flame retardant performance, due to the effect of candle core, it will interfere with the flame retardant system and affect the flame retardant effect;
7. Reduce the surface luster;
8. Increasing moisture absorption;
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 treatment will increase the impact strength. To make the brittleness of the material not decrease greatly, choose a certain length of the glass fiber.
Conclusion: To obtain a good impact intensity, the surface treatment of the glass fiber and the length of the glass fiber are very important.
Fiber content: The amount of fiber content of the product is also a key issue. my country generally adopts integer content such as 10%, 15%, 20%, 25%, and 30%, while foreign abroad determines the content of glass fiber according to the use of products.
