Excessive anisotropy of PBT reinforced products
Fenómeno del problema
The performance difference between the flow direction and the perpendicular direction of glass fiber reinforced PBT products is too large (>50%).
Análisis de la causa
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.
Solución
Optimize the gate position to make the glass fiber orientation distribution uniform; use mineral/glass fiber hybrid fillers to reduce anisotropy.
Conclusión clave
PBT anisotropy needs to be considered at the design stage.
