PLA Brittleness Shortcoming
Sorun Belirtisi
PLA products shatter when dropped, snap-fits break during assembly, toughness tests fail
Neden Analizi
PLA molecular chains are highly rigid and crystallization is difficult, with poor impact resistance, low toughness, hard and brittle; the elongation at break is usually below 10%, which is the biggest limitation of its application
Çözüm
①Select toughened modified PLA for load-bearing parts; ②Structure avoids brittle-sensitive designs such as thin-wall snap-fits; ③Blend with PBAT/PCL etc. for toughening; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Brittleness is PLA's first shortcoming; toughening modification and structural avoidance are the two response routes; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
