Fiber orientation causing severe anisotropy
Fenómeno do problema
The longitudinal and transverse shrinkage rates and strength differences of the product exceed 50%, and dimensions are unstable
Análise das causas
Long fibers are highly oriented along the flow direction during filling; a single gate position causes unidirectional flow orientation; holding pressure further strengthens fiber orientation
Solução
Optimize the gate layout to achieve multi-directional filling; reduce holding pressure to reduce secondary orientation; consider in product design that the orientation direction is consistent with the main load-bearing direction
Conclusão principal
Uniform fiber orientation control is the key to reducing anisotropy
