| Summary: | This paper investigated stamp forming performance of two aluminum-based Fiber-metal laminates
(FMLs) with different fiber-reinforced composites using finite element analysis. Given the
inherent thermal-dependent properties of fiber-reinforced polypropylene, the effect of elevated
temperature on its forming behavior is worthy of concern. Furthermore, the elevation in temperature
also influences the bonding within the constituent lamina. Both factors were integrated
in the modelling. By investigating the through-thickness strain evolution throughout the stamping
process, the forming mode of each layer, as well as their interactions, were better understood.
Results suggested that the flow of matrix and the rotation at the intersections of fiber strands can
be promoted at elevated temperature, which transforms the forming performance of FMLs close to
that of monolithic aluminum. These results propose means to improve the forming performance
of FMLs. |
