Warp Analysis considering anisotropic properties due to fiber orientation

Issues due to fiber orientation

Warpage due to anisotropic properties

When the fiber orientation state change, anisotropic properties in the coefficient of linear expansion are affected, which affects warpage. This analysis is essential for considering molding condition and mold shape.

Impact of gate position on fiber orientation

When the gate position differs, the progress of the resin melt front changes, and so does the orientation state. As a result, the anisotropy of the properties(Young's modulus, coefficient of linear expansion) also varies, and this is thought to impact the amount of warpage.

In this case, a study is conducted for products with two different gate positions, as shown below.
