The invention discloses a high-performance compound material prepared by a recycled waste carpet PA66 material and a preparation method thereof. The composing formula of the material is formed by the following components by weight percentage: 54-60% of recycled waste carpet PA66; 0-10% of a flexibilizer; 30-35% of alcoholysis-resistant glass fiber; and 0-1% of a tackifier and an antioxidant. The beneficial effects of the high-performance compound material are as follows: firstly, the recycling of the recycled waste carpet material is realized, and the recycling of the resource is realized, the material is green and environmental; secondly, the recycled waste carpet PA66 is modified so as to improve the performance of the recycled waste carpet PA66 and the cohesiveness of the PA66 and the alcoholysis-resistant glass fiber interface, so the compound material has good mechanical property, hydrolysis resistance or alcoholysis resistance and so on; and the application for important parts, such as an automobile front-end module, an automobile engine fan, an oil pan and a radiator water chamber, can be realized.
