摘　　要：基于ANSYS软件建立了碳纤维增强复合材料有限元模型,采用Newmark法对不同温度下碳纤维增强复合材料的力学性能进行研究.结果表明：温度对碳纤维增强复合材料的应力、变形均有较大影响,碳纤维增强复合材料的应力在25 ～ 80℃时,随温度的升高呈明显上升趋势,当温度达到80 ～ 100℃时,由于复合材料中的树脂达到其软化温度,碳纤维增强复合材料承载能力显著降低,而100℃之后应力随温度增加呈平缓下降趋势;碳纤维增强复合材料的变形在25 ～ 120℃时始终呈上升趋势.Based on ANSYS software to establish finite element model of carbon fiber reinforced com-posites, we study the mechanical property of carbon fiber reinforced composites with different tem-perature using Newmark method. The result analysis shows that temperature has great influence ondeformation and stress of it. Stress has an obviously--increasing trend from room temperature to80 ℃ ,and decreases rapidly when the temperature goes from 80 ℃ to 100 ℃ , because resin withinthe composite material reaches the melting point. But it decreases slowly when the temperature isover 100 ℃. The change of strain increases rapidly with the temperature rising from room tempera-ture to 120 ℃.
