In a fiber-reinforced composite, ANISOTROPY (direction-dependent properties) is MAXIMUM when:
A{'text': 'Fibers are UNIDIRECTIONAL and CONTINUOUS', 'label': 'B'}
B{'text': 'Reinforcement is particulate', 'label': 'C'}
C{'text': 'Fibers are randomly oriented', 'label': 'A'}
D{'text': 'Reinforcement is flake-shaped', 'label': 'D'}
Answer & Solution
Correct answer: A. {'text': 'Fibers are UNIDIRECTIONAL and CONTINUOUS', 'label': 'B'}
All fibers aligned in one direction ⇒ strongest along fiber axis, weakest transverse. Random orientation averages out anisotropy. Particulate ⇒ nearly isotropic.
