← ScienceWhich outcome occurs when a torsional load exceeds adhesive bonds securing fiber within a composite shaft?
A)Progressive delamination initiates and propagates rapidly✓
B)Matrix carbonizes inhibiting fiber pullout
C)Resin softens equally distributing stress
D)Fibers elongate reversibly restoring torque
💡 Explanation
Progressive delamination will occur because the exceeding torsional load breaks the adhesive bonds. The resulting interlaminar crack growth reduces shaft stiffness catastrophically, therefore this answer is correct rather than alternatives because other outcomes are physically impossible.
