摘要
对用低压浸渗法制备石墨（碳）长纤维镁基复合材料进行了研究。结果表明，制备工艺条件对复合状况、界面反应及复合材料性能均有明显影响。通过纤维表面ＳｉＯ２涂层处理和优化浸渗工艺，可成功地制备出高性能的复合材料，拉伸断裂强度可达５０９ＭＰａ，模量亦可达１４２ＧＰａ。
Gr(C)/Mg composites were prepared by low pressure infiltration. Results showed that the infiltration, interface reaction and tensile stress of composite materials were affected obviously by fabrication conditions. Through fiber SiO 2 coating and optimum infiltration processing, composite materials with high mechanical properties were produced. Its tensile strength was as high as 509 MPa and modulus of elasticity 142 GPa.
