提出了一种涂覆氧化铝涂层的碳纤维增强铝合金复合材料的制备和烧结工艺。模拟原子的运动、能量变化和结构演化,结合SEM、FT-IR观察碳纤维表面处理对碳纤维的影响,探索提高复合材料力学性能最有效的烧结工艺。结果表明,碳纤维增强铝合金复合材料抗拉强度随预热温度升高先增大后减小,随烧结渗透温度升高而降低。在预热温度为500℃、烧结温度为700℃时,抗拉强度最大为417.3MPa。
A preparation and sintering process of carbon fiber reinforced aluminum alloy composite material coated with alumina coating was proposed.By simulating the motion,energy changes and structural evolution of atoms combined with SEM and FT-IR,the effect of carbon fiber surface treatment on carbon fibers was observed to explore the most effective sintering process for improving the mechanical properties of composite materials.The results showed that the tensile strength of carbon fiber reinforced aluminum alloy composite materials increased first and then decreased with the increase of preheating temperature.It decreased with the increase of sintering infiltration temperature.At a preheating temperature of 500℃ and a sintering temperature of 700℃,the maximum tensile strength was 417.3MPa.
