Characterization of multilayered carbon-fiber-reinforced thermoplastic composites for assembly process

摘要

The aim of this research work is to characterize the mechanical behavior of multilayered carbon-fiber-reinforced polyphenylene sulfide composites with the application to assembly process of nonrigid parts. Two anisotropic hyperelastic material models were investigated and implemented in Abaqus as a user-defined material. An inverse characterization method was applied to identify the parameters of these material models. Finite element simulations at finite strains of a flexible composite sheet were carried out. Numerical results of sheet deformation were compared with the experimental results in order to evaluate the appropriateness of the material models developed for this application.
