Experimental and numerical studies of the open-hole compressive strength of thin-ply CFRP laminates

Thin prepregs with thickness of less than 0.06 mm support flexible lamination design because it is possible to apply various stacking sequences. The objective this study elucidate the effects layer and sequence on open-hole compressive (OHC) strength for thin-ply carbon fiber reinforced plastic composite (CFRP) laminates. Details OHC CFRP laminates were evaluated experimentally. Furthermore, finite element analyses incorporating Hashin’s 2-D failure criteria a cohesive zone model conducted evaluate damage progression behavior. Results demonstrated that numerical was useful predicting
