Abstract
The present invention provides a polyamide composite material, which includes the following components in parts by weight: 25-85 parts of a polyamide resin; 10-50 parts of a glass fiber; 5-25 parts of polytetrafluoroethylene; and 0.1-2 parts of at least one of a K/Na/Ca/Mg/Ba/Zn/Li/Al salt of montanic acid. The montanate can effectively inhibit free hydrogen fluoride in the polytetrafluoroethylene, thereby effectively inhibiting free silicon in the glass fiber and improving the electrical performance of the material.
