Minimizing the Weight and Cost of an Aluminum Deck Lid

A minimum weight aluminum deck lid has been designed using 0.71 mm thick 6010 alloy sheet. Minimizing material weight will contribute to minimum cost.

A stiff dimpled inner panel design allows aluminum panel gauges to be controlled by strength requirements. The deck lid's calculated overall stiffness is comparable to that of steel designs. Stretch-stamping and rope hemming are recommended forming and assembly methods.
