Interface debonding between carbon fiber and resin matrix
Problem Phenomenon
When the composite material is stressed, fibers are pulled out/debonded from the matrix
Cause Analysis
The bonding strength between the fiber and the resin interface is insufficient; the sizing agent on the fiber surface does not match the resin; the resin does not fully wet the fibers
Solution
Select a carbon fiber sizing agent matching the resin system; optimize fiber surface treatment (such as anodic oxidation, plasma); control the '2079851475616104453 to promote resin wetting
Key Takeaway
Interface quality determines the mechanical and long-term performance of composite materials
