Reasons and benefits of using JAXA Supercomputer System
High-performance parallel computing is necessary because the numerical model is computationally expensive.
Achievements of the Year
A simplified finite element modeling methodology was developed to predict the thermal deformation of carbon fiber reinforced polymer (CFRP) laminates during their automated fiber placement (AFP) manufacturing process. The obtained results are as follows.
(1) The finite element model predicts the thermal deformation of CFRP laminates by taking account of the temperature difference between prepreg layers from a thermal analysis. In this model, the thermal deformation states of pre-placed layers are used as initial conditions.
(2) The modeling process is automated to achieve savings in the modeling time.
(3) The predicted deformation states were in qualitative agreement with the experimental result (Fig. 1).
(4) Based on the results of the prediction accuracy and computational time, it was found that the finite element model is effective for predictig the thermal deformation of CFRP laminates.
