Glass fiber reinforcement is an effective method to improve the rigidity of pure PA6 materials and improve the shortcomings of poor creep resistance and reduced mechanical properties in humid environments. The content of glass fiber has a huge impact on the performance of PA6 glass fiber reinforced materials. It is important to explore the rules. Very practical. Haiyang PA6 combines its own experience and communication with customers to briefly describe it as follows:

       1. As the glass fiber content increases, the tensile strength of the material increases and the impact strength decreases. When the glass fiber content is 30%, the comprehensive performance of PA6 glass fiber reinforced materials is optimal.

       2. As the glass fiber content increases, the hardness and density of the material gradually increase. This is because the hardness and density of glass fiber are higher than pure PA6 materials.

       3. As the glass fiber content increases, the notched impact strength of PA6 glass fiber reinforced materials increases significantly. It reaches the maximum when the content is 15%, which is about 5 times higher than that of pure PA6 materials, and then decreases.

       4. As the glass fiber content increases, the friction resistance of the material is significantly improved. When the glass fiber content is 15%, the friction factor and wear amount of the material reach the lowest.

       5. When the content is higher than 15%, the friction resistance of the material continues to decrease. When it reaches 30%, the friction factor and wear amount exceed that of pure PA6 material. This is because the addition of glass fiber takes priority to bear most of the load generated when the PA6 glass fiber reinforced material is rubbed. However, when the glass fiber content reaches 30%, the bonding performance of the glass fiber and the PA6 matrix becomes worse, and the wear resistance is greatly reduced. .
