Examples of MATRIX MATERIALS commonly used in PMCs include:
A{'text': 'Silicon carbide and alumina', 'label': 'C'}
B{'text': 'Tungsten and cobalt', 'label': 'D'}
C{'text': 'Epoxy, polyester, vinyl ester (thermosets) and PEEK, nylon, polypropylene (thermoplastics)', 'label': 'B'}
D{'text': 'Steel and aluminum', 'label': 'A'}
Answer & Solution
Correct answer: C. {'text': 'Epoxy, polyester, vinyl ester (thermosets) and PEEK, nylon, polypropylene (thermoplastics)', 'label': 'B'}
Polymer matrices are organic. Thermosets (epoxy, polyester) dominate aerospace. Thermoplastics (PEEK, nylon) are used in automotive and consumer applications. Steel/aluminum = MMC matrices; SiC/Al₂O₃ = CMC matrices.
