1. The impact of long and short fibers on the quality of reinforced nylon:
The diameter of fiberglass is generally between 10 and 20 microns. If it is too thick, it will result in poor adhesion, while if it is too fine, it will be cut into powder by the machine and will not have the effect of reinforcement; There are two types of glass fiber lengths: long glass fiber and short glass fiber. Short glass fiber is severely sheared, and its length is shorter. The longer the fiber, the better the reinforcement effect. However, the rough surface of the product increases the difficulty of forming; The effect of pre-treatment (such as coupling agent infiltration) on the surface of fiberglass will be better.

2. The effect of glass fiber content on the quality of reinforced nylon PA:
In terms of glass fiber content, the mechanical properties and thermal deformation temperature increase with the increase of glass fiber content. If the content is too high, the surface roughness and fluidity of the product decrease. When it reaches 30%, the mechanical properties reach their peak, and after exceeding 30%, the performance gradually decreases; The influence of basic temperature, when the temperature is too low, the glass fiber coating effect is poor, the spline is rough and dull, and the impact performance is poor. If the temperature is high, it may promote the decomposition or even carbonization of PA66, directly affecting the mechanical properties; The impact of screw speed, low glass fiber content high speed, high glass fiber content low speed.
