Experimental Determination of Compressive Residual Strength of a Carbon/epoxy Laminate after a Near-edge Impact

In this work has been estimated the compressive residual strength and Young modulus of a Carbon/Epoxy laminate after a near-edge impact. Near-edge impacts were performed with a Charpy pendulus, modified in order to obtain impact tests comparable with the ASTM D7136/D7136M-12; whereas compressive tes...

Description
Summary:In this work has been estimated the compressive residual strength and Young modulus of a Carbon/Epoxy laminate after a near-edge impact. Near-edge impacts were performed with a Charpy pendulus, modified in order to obtain impact tests comparable with the ASTM D7136/D7136M-12; whereas compressive tests were performed using the Wyoming Combined Loading Compression (CLC) Test Method, described in ASTM D 6641/D 6641M-09. The CLC Test fixture presents many advantages: the load applied to the specimen is combined (end-load combined with shear-load), high reproducibility and reliability of the results, the lightness of the fixture, possibility of use specimens without tabs. Twenty-six cross-ply ([0°/90°]ns) coupons were tested in the compressive tests: 10 after a 3J impact (5 central impact and 5 near-edge impact), 10 after a 5J impact (5 central impact and 5 near-edge impact), 6 specimens without impacts.
