Fiber Reinforcement of PLA Products
Problem Phenomenon
Poor interface of reinforced composites.
Cause Analysis
Natural fiber reinforced PLA such as hemp fiber has weak interfacial bonding; fiber dispersion is also a problem.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Fiber surface treatment; ②Add compatibilizer; ③Optimize mixing and dispersion; ④Verify interfacial strength.; After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Natural fiber reinforced PLA is an environmental direction; interface engineering is the key.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
