Which consequence results when epoxy used in carbon fiber laminates undergoes excessive crosslinking?

A)Increased overall brittleness develops
B)Enhanced ductility and flexibility occur
C)Improved resistance to solvent absorption
D)Reduced tensile strength is typically observed

💡 Explanation

Excessive crosslinking causes increased brittleness because the reaction creates more covalent bonds between polymer chains preventing chain movement; therefore, a brittle fracture occurs rather than plastic deformation because chains can't slide past each other.
