Excessive anisotropy of PBT reinforced products
Sorun Belirtisi
The performance difference between the flow direction and the perpendicular direction of glass fiber reinforced PBT products is too large (>50%).
Neden Analizi
The glass fiber is highly oriented in the mold filling flow direction, causing anisotropy of mechanical properties; the product design and gate position are improper.
Çözüm
Optimize the gate position to make the glass fiber orientation distribution uniform; use mineral/glass fiber hybrid fillers to reduce anisotropy.
Temel Çıkarım
PBT anisotropy needs to be considered at the design stage.
