Compressive bearing capacity and failure mechanism of CFRP–aluminum laminate column with single-channel cross section

The axial compressive bearing capacity, failure modes, and failure mechanisms of carbon fiber-reinforced aluminum laminate (CARALL) columns with single-channel cross sections were studied in detail. In this study, two types of short CARALL specimens with a 5/4 configuration were first fabricated usi...
