Composite materials are most commonly classified at the FIRST level by:
A{'text': 'Matrix constituent (Organic / Metal / Ceramic Matrix Composite)', 'label': 'B'}
B{'text': 'Manufacturing process', 'label': 'C'}
C{'text': 'Cost', 'label': 'D'}
D{'text': 'Reinforcement form (fiber, particulate, laminar)', 'label': 'A'}
Answer & Solution
Correct answer: A. {'text': 'Matrix constituent (Organic / Metal / Ceramic Matrix Composite)', 'label': 'B'}
Top-level classification: Organic Matrix Composites (OMC, including PMC and Carbon-Carbon), Metal Matrix (MMC), Ceramic Matrix (CMC). Reinforcement form is the SECOND-level classification.
