← ScienceWhich consequence results when a carbon fiber composite part exceeds designed strain limits?
A)Matrix cracking initiates delamination✓
B)Debonding decreases component stiffness
C)Fibers directly undergo plastic deformation
D)Resin oxidation induces surface blistering
💡 Explanation
Exceeding strain limits starts matrix cracking because micro-cracks disrupt the stress transfer mechanism. Therefore, delamination risk increases rather than plastic deformation or oxidation, which require different failure modes and conditions.
