← ScienceWhich outcome occurs when a tensile load exceeds composite's adhesion?
A)Interfacial debonding initiates crack propagation✓
B)Fibers undergo catastrophic tensile failure
C)Resin matrix experiences plastic deformation
D)Oxidation accelerates material property degradation
💡 Explanation
Interfacial debonding initiates a crack because cohesive strength is exceeded causing crack growth via **adhesive failure**, therefore debonding occurs which leads to failure, rather than the fiber itself breaking or simply oxidizing.
