In a Fiber-Reinforced Composite (FRP), the PRIMARY function of the FIBERS is to:
A{'text': 'Carry loads along their longitudinal direction (high tensile strength + stiffness)', 'label': 'B'}
B{'text': 'Resist moisture', 'label': 'C'}
C{'text': 'Bond layers together', 'label': 'A'}
D{'text': 'Provide color', 'label': 'D'}
Answer & Solution
Correct answer: A. {'text': 'Carry loads along their longitudinal direction (high tensile strength + stiffness)', 'label': 'B'}
Fibers carry the primary axial load thanks to their high tensile strength/stiffness. Matrix transfers stresses between fibers and protects them, but matrix typically carries far less load.
