New composite Humvees shed 900 pounds of weight

Humvees are synonymous with transporting troops on the ground during times of war. The ubiquitous workhorses are also pretty lacking when it comes to protection from enemy fire and improvised explosive devices (IEDs).

The U.S. Army in conjunction with AM General Corp. and TPI Composites Inc. are looking to composite materials to give its soldiers a better chance at surviving treacherous working conditions on Iraq.

Its latest test bed is a Humvee that features a frame and body made of composite materials. Resin material is used to bond together balsa wood, carbon reinforcements, fiberglass and foam. The use of composite materials on the Humvee shaves 900 pounds off the usual 10,000 to 12,000 pound vehicle weight.

"We can put the strength where we need it," said TPI Composites CEO Steven Lockard. "Every pound of weight we save, that weight is being added back to the vehicle in armor and mine-blast protection."

Additional armor could be placed under and around the cabin area of the Humvee to protect the passengers, while the composites materials alone could be used for the hood and fenders.

Predictably, the new composite-bodied Humvees are slightly more expensive than their conventional counterparts and the Army still hasn't made a firm commitment to purchasing the vehicles.

With that said, TPI Composites is fully prepared should the Army give the company the green light. "We could ramp up pretty quickly to most any volume that would be desired," said Lockard.

How does government borrowing negatively affect our economy? Seems to me we've had large-scale government borrowing for many years now, and it has been steadily increasing during good times and bad. I don't see any kind of correlation between the two.

Go look at the actual valuation of the dollar in comparison with other countries to see how it negatively affects our economy (or perhaps more importantly, negatively affects the consumer).

As we spend more and make less, the relative value of the dollar goes down.

So, consider that when you go to someplace like Mexico, one american dollar can buy you a lot of goods & services in Mexico. Now consider what happens if that suddenly the american dollar becomes worth less. All that cheap stuff made in Mexico is now comparatively expensive. As a result, Americans end up paying more money for the same stuf that used to be cheap.

This is a big deal when the vast majority of goods purchased in the US are made in foreign countries.

And when US corporations spend more money and get less overall, it has a major negative impact on our economy.
