The role of the MATRIX in a fiber-reinforced composite is to:
A{'text': 'Provide electrical insulation only', 'label': 'D'}
B{'text': 'Be the strongest phase', 'label': 'C'}
C{'text': 'Transfer load between fibers via shear, protect fibers from environmental damage, and prevent fiber buckling', 'label': 'B'}
D{'text': 'Carry most of the load', 'label': 'A'}
Answer & Solution
Correct answer: C. {'text': 'Transfer load between fibers via shear, protect fibers from environmental damage, and prevent fiber buckling', 'label': 'B'}
Matrix functions: (1) load transfer between fibers via interfacial shear, (2) environmental protection (moisture, chemicals), (3) lateral support to prevent fiber buckling. Fibers carry most of the axial tensile load; matrix carries shear.
