【摘要】 金属夹层复合材料有着隔音降噪、防火、抗电磁屏蔽等优点，在碳纤维复合材料平板中铺设金属铁片夹层，以热传导和固化动力学为理论基础建立金属夹层复合材料平板在固化过程中的ABAQUS分析模型。通过对有限元计算结果与实验结果进行比对，研究了铺层角度、金属铁片夹层、金属夹层材料的热膨胀系数3个参数对金属夹层复合材料平板固化变形的影响。结果表明，采用0°或90°的铺层角度、在复合材料中铺设金属铁片夹层、选择热膨胀系数较大的金属夹层材料都能够有效减小金属夹层复合材料平板的固化变形。计算结果与实验结果相比相差在9%左右，验证了结果的可靠性，也为金属夹层复合材料的固化变形计算提供了一定的研究基础。更多还原

【Abstract】 Metal interlayer composite materials have the advantages of sound insulation, noise reduction,fire resistance, and anti-electromagnetic shielding. A metal iron sheet interlayer is laid in the carbon fiber composite plate, and the ABAQUS analytical model of the metal interlayer composite plate in the curing process is established based on the theory of thermal conduction and curing kinetics. The effects of three parameters,namely the layup angle, the metal iron interlayer, and the thermal expansion coefficient of the metal interlayer material, on the solidification deformation of the metal sandwich composite material are studied, by comparing the finite element calculation results and the experimental results. The results show that the solidification deformation of the metal interlayer composite plate is effectively reduced with adopting a layup angle of 0° or 90°, laying a metal iron interlayer in the composite material, or selecting a metal interlayer material with a larger thermal expansion coefficient. Compared with the experimental results, the deviation of the calculation results is about 9%, which verifies the reliability of the results and provides a certain research basis for the calculation of the solidification deformation of metal interlayer.更多还原
