1. 研究目的与意义（文献综述）
1 development and significance of hot forming technology of fmls
1.1 introduction of fmls
fiber metal laminate (fml)[1] is a kind of interlaminar hybrid composite, also described as super hybrid laminate, which is made of metal sheet and fiber composite in alternate layers and solidified under certain temperature and pressure.
2. 研究的基本内容与方案
2 research content and methodology
2.1 main research content
the main content of this paper is to study the stress-strain behavior and deformation behavior of fmls in hot gas forming. according to the existing hot forming technology, the fmls are heated in the die, then applying the physical characteristics of the thermal soften and solidify under heat. the phenomenon relationship can be further obtained, from which scheme and the stress-strain behavior and deformation of the components are easily obtained. hence, the goal of improving the interface strength and avoiding the wrinkle defects in the suspended area can be realized.
