A modified PA66 material comprises the following raw material components by weight percentage: 50% to 84% of PA66 resin, 10% to 35% of continuous glass fiber and/or chopped glass fiber, 1% to 5% of first milled glass fiber with an average fiber length of 30 渭m to 130 渭m, 5% to 10% of second milled glass fiber with an average fiber length of 150 渭m to 550 渭m, and 0% to 8% of additives. The modified PA66 material has a small difference between longitudinal and transverse shrinkage rates, and heat resistance and mechanical properties comparable to conventional glass fiber-reinforced PA66 materials, and can be applied to precision parts with high dimensional requirements.
