Composite materials have become popular because of high mechanical properties and lightweight. Aluminum/carbon nanotube is one of the most important metal composite. In this research, mechanical properties of aluminum/carbon nanotube composite were obtained using molecular dynamics simulation. Then, effect of temperature on stress–strain curve of composite was studied. The results showed by increasing temperature, the Young’s modulus of composite was decreased. More specifically increasing the temperature from 150 K to 620 K, decrease the Young’s modulus to 11.7%. The ultimate stress of composite also decreased by increasing the temperature. A continuum model of composite was presented using finite element method. The results showed the role of carbon nanotube on strengthening of composite.

分子动力学模拟温度对铝/单壁碳纳米管纳米复合材料性能的影响

复合材料因其高机械性能和轻质而变得流行。铝/碳纳米管是最重要的金属复合材料之一。在本研究中，铝/碳纳米管复合材料的力学性能是通过分子动力学模拟获得的。然后，研究了温度对复合材料应力-应变曲线的影响。结果表明，随着温度的升高，复合材料的杨氏模量降低。更具体地说，将温度从 150 K 提高到 620 K，将杨氏模量降低到 11.7%。复合材料的极限应力也随着温度的升高而降低。使用有限元方法提出了复合材料的连续模型。结果表明碳纳米管对复合材料的强化作用。
