High fatigue resistance glass fiber reinforced nylon material and preparation method thereof

Abstract

The invention relates to a high fatigue resistance glass fiber reinforced nylon material and a preparation method thereof. The fatigue-resistance glass fiber reinforced nylon material comprises the following raw materials in percentage by weight: 48.2 to 79.7 percent of nylon resin, 20 to 50 percent of glass fiber, 0.1 to 0.6 percent of antioxygen, 0.1 to 0.6 percent of lubricant, 0.1 to 0.6 percent of nucleating agent. The high fatigue resistance glass fiber reinforced nylon material is prepared by melting and blending the components at 210 to 300 DEG C. The glass fiber reinforced nylon material prepared by the method has high fatigue-resistance performance as well as high mechanical performance and high surface performance. The production process is mature. The glass fiber reinforced nylon material can be widely used for making parts around automotive motors and parts in other industries.
