%X 采用叠层模压法制备了纳米Al2O3-碳纤维织物多尺度增强聚酰胺基（nano Al2O3-CFF/PA6）复合材料层压板。借助场发射扫描电子显微镜（FESEM）、同步热分析仪（TGA/DSC）和FTIR，研究了模压温度、压力和纳米Al2O3加入量等因素对nano Al2O3-CFF/PA6复合材料力学性能的影响。研究表明：在模压温度为230℃、模压压力为3 MPa和保压时间为15 min时，CFF/PA6层压板的弯曲强度为250.3 MPa，层间剪切强度为87.6 MPa，平行层厚方向的冲击强度为41.2 MPa，垂直层厚方向为9.6 MPa。当基体中的Al2O3含量达到6wt%时，nano Al2O3-CFF/PA6层压板的弯曲强度为387.6 MPa，层间剪切强度为35.7 MPa，平行和垂直层厚方向的冲击强度分别为80.3 MPa和25.6 MPa。 Laminated film compression-molding was used to fabricate nano Al2O3-carbon fiber multi-scale reinforced PA6 matrix (nano Al2O3-CFF/PA6) composite laminates. The effect of molding temperature, compression pressure and nano Al2O3 content on the properties of nano Al2O3-CFF/PA6 laminates were investigated by FESEM, thermogravimetric analysis/differential scanning calorimetry simultaneous thermal analyzer(TGA/DSC) and FTIR. The results show that the flexural strength, interlaminar shear strength, and parallel/vertical impact strength of the CFF/PA6 laminates reach 250.3 MPa, 87.6 MPa, 41.2 MPa and 9.6 MPa while they are fabricated at 230℃, 3 MPa holding 15 min. When the content of nano Al2O3 in the matrix reaches to 6wt%, the corresponding mechanical strength of nano Al2O3-CFF/PA6 laminated composite are 387.6 MPa, 35.7 MPa, 80.3 MPa and 25.6 MPa, respectively.
