Fiber retention length of carbon fiber reinforced thermoplastics (CFRTP)
Problem Phenomenon
The fiber length in CFRTP is far below the original length
Cause Analysis
The strong shear of the screw during '2079851475616104452 cuts the fibers
Solution
Use low-shear screws and processes; optimize gates and runners to reduce shear
Key Takeaway
The retention of fiber length determines the performance level of CFRTP
