Table 6 The effect of the lay-up technique on the relative damage measured through the tensile test.
Specimen | Relative peak load (%) | Relative displacement corresponding to peak load (%) | Relative max. displacement (%) | Relative tensile stiffness (%) |
|---|---|---|---|---|
[Al/0°/90°/0°/Al] hand lay-up | − 60.13 | 2.14 | − 35.3 | − 60.96 |
[Al/0°/90°/0°/Al] sandwich | − 62.41 | 7.16 | 14.33 | − 64.92 |
[0°/90°/0°] hand lay-up | − 51.79 | 75.89 | 62.59 | − 72.59 |
