Abstract

Automobile lightening is a direct and effective measure to realize energy saving and emission reduction. Using aluminum alloy and carbon fiber reinforced polymers (CFRP) composite materials to manufacture automobile parts can greatly reduce weight while enhance the overall strength and balance the overall toughness of the composite materials, and obtain high impact energy absorption capacity. In order to explore the feasibility of stamping-joining by hot stamping process for aluminum alloy and CFRP, using peeling test, the effects of different surface treatments of the aluminum alloy, different holding time and pressures in stamping-bonding stage on the strength of 6061 aluminum alloy/CFRP composite joints were studied. The results indicated that the joint shear strength after grinding, alkali washing and pickling the aluminum alloy’s surface was 2.5 MPa, 4.3 MPa and 4.6 MPa respectively, which were increased by 155.4%, 338.77% and 369.38%, respectively. In the stamping-joining stage, when the holding time was less than 60 s, the joint shear strength increased rapidly to about 4.90 MPa, whereas the holding time is more than 60 s, the joint shear strength decreased and kept stable, remaining in the range of 3.92 to 4.34 MPa. When holding pressure was 1.0 MPa, the maximum shear strength was 4.90 MP; however, increasing the holding pressure may lead to resin overflowing.
