- •
Delamination growth of a carbon/epoxy composite was measured by acoustic emission.
- •
Acoustic emission based crack growth curves for + 80 °C and − 55 °C were identified.
- •
A trend between the AE event rate, the cumulative AE, and fibre breakage was found.
- •
Maximum of AE events was present in the area of fibre-bridging.
