| Résumé : |
In this study, the warping mechanism was examined in terms of the difference in warpage behavior due to the presence or absence of fiber filler, using a ribbed plate. It was found that the warping mechanism due to anisotropic shrinkage is caused by the filler orientation distribution and filler form, including its size and geometry. It is seen that the sensitivity (the effect of the rib thickness on the amount of warpage) increased as the glass flake content was increased in PBT-hybrid filler. From this result, the glass flake used in this study were sufficiently small and that aspect ratio was approximately 2 compared with the glass fiber (aspect ratio: 10 ~ 20). It can be inferred therefore that the glass flake acted like spherical filler, which contributed to reducing the anisotropic shrinkage. |
