MULTIPHASE fibers (e.g., carbon-core with SiC outer sheath) are designed to:
A{'text': 'Be cheaper', 'label': 'D'}
B{'text': 'Look fancy', 'label': 'A'}
C{'text': 'Save weight only', 'label': 'C'}
D{'text': 'COMBINE PROPERTIES — high stiffness of the core with environmental resistance of the sheath; relevant when neither single material gives both', 'label': 'B'}
Answer & Solution
Correct answer: D. {'text': 'COMBINE PROPERTIES — high stiffness of the core with environmental resistance of the sheath; relevant when neither single material gives both', 'label': 'B'}
Multiphase / coated fibers offer property combinations a single material cannot deliver. E.g., a carbon core for stiffness with a SiC outer for high-temperature oxidation resistance. Manufactured via CVD or sol-gel coating.
