PAEK and carbon fiber interfacial bonding problem
Problem Phenomenon
The mechanical properties of CF/PAEK are lower than expected
Cause Analysis
Fiber surface treatment does not match PAEK high-temperature processing conditions; fiber impregnation insufficient
Solution
Select a PAEK dedicated sizing agent; optimize the processing temperature window; add fiber surface treatment
Key Takeaway
Interface quality is the decisive factor for CF/PAEK performance
