摘要：
Fiber Metal Laminate（FML）is a new type of lightweight hybrid material，which is gradually used in the field of transportation equipment such as automobiles. However，its forming process is affected by various parameters，and the distribution law of stress and strain in the forming process is still unclear. In this paper，T300 carbon fiber aluminum alloy composite laminate is selected as the research object. Its stamping forming process is simulated by ABAQUS finite element software，and the accuracy is verified. The stress distribution and wall thickness change law of FML under the influence of factors such as the type of prepreg，the thickness of the laminate and the number of laminates are studied. The results show that the calculation of the established FML stamping model is accurate. The type of prepreg mainly affects the stress distribution and wall thickness change of the fiber layer. The thickness of the laminate and the number of laminate have impact on the wall thickness change of each layer. By reducing the thickness of the laminate or increasing the number of layers can alleviate the problem of excessive thinning. The thickness and number of layers also affect the stress distribution of the aluminum alloy layer. With the increase of the thickness and number of layers，the stress distribution of the aluminum alloy layer tends to be uniform. © 2023 SAE-China. All rights reserved.
