Table 8 The effect of the lay-up technique on the relative damage measured through the flexural test.
Specimen | Relative peak load (%) | Relative deflection corresponding to peak load (%) | Relative max. deflection (%) | Relative flexural stiffness (%) |
|---|---|---|---|---|
[Al/0°/90°/0°/Al] hand lay-up | − 22.33 | 30.65 | 1.65 | − 40.6 |
[Al/0°/90°/0°/Al] sandwich | − 45.89 | − 15.04 | − 5.27 | − 36.31 |
[0°/90°/0°] hand lay-up | − 52.21 | 26.59 | 26 | − 62.25 |
