A BASIC requirement for a matrix material in FRP is:

Question

Accepted Answer

B. {'text': 'STRAIN AT BREAK must be LARGER than the strain at break of the fibers it holds', 'label': 'B'}

If the matrix were to fail at lower strain than fibers, the composite would fail at matrix failure — fibers never reach their capacity. Matrix strain-at-break > fiber strain-at-break ensures fibers carry load until their own failure.
