Actually they are very strong and are designed to transfer energy.

transfering energy is the crumpling up effect. the bar its self is weak, yet it absorbs the energy..... why else would it be made from aluminum, other than weight?

think stepping on a coke can.

Aluminum is stronger than you think,and not all bumper reinforcements are made of aluminum some are steel,high strength steel ,and ultra high strength steel.
And now on some imports they are a composite metal/fiberglass

Agreed. They transfer energy around the driver's cabin and not into the engine which could push into the cabin. They are NOT meant to simply crumple.
