A hood is constructed in three layers with a special honeycomb-shaped structure has successfully performed its first major crash tests, which show that a collision between foam box a pedestrian's head and the hood of a car is reduced by up to 60 percent. By Thomas Djursing April 25, 2011 at. 15:09
Which manufacturer that is involved is still secret, but the hood is made of English Cellbond and passed the renowned foam box crash test Euro NCAP. It shows that the power of the collision between a head on a pedestrian, and a bonnet of a car will be reduced by 50 to 60 percent over conventional hoods, writing partner Anglia Ruskin University in a statement.
In Europe, 20 percent of pedestrian fatalities in traffic, while it is 14 percent in the US and 47 percent in Thailand, which is the country where most pedestrians are killed in relation to other road users. foam box During collisions with cyclists and pedestrians is the typical cause of death that driver head is crushed against the hood. Therefore, a large part of the evolving security focused around the hood.
For several years Cellbond work with cushioning products that mimic the cellular structure of a beehive. Cellbond are even reluctant details about their patented hood, but when the company in 2007 conducted its own crash test was the hood built by a honeycomb structure designed in aluminum.
Since the company has developed a so-called Pressure Load technology in which the cushioning layer resembling foam box a layer of egg cartons. According Cellbond gives the conical elements of the material a great strength, and the flat top makes it easier for scientists to mount the structure of other parts. About Pressure Overload technology is being used in the new hood is unclear, but according to the British engineering media The Engineer, the hood made of three layers consisting of a "shock absorber placed between sheets of aluminum with a special etched geometric pattern designed based on computer simulations. " Raised foam box hood can reduce fatal accidents
It is important to note that the challenge for the British scientists has been to make a bonnet that has the same design as the current bonnet, and is not making new demands on the cars shape.
Will carmakers reduce the number of dead pedestrians, they may in fact just increase the air space between the radiator bonnet lower part and the engine foam box itself. Fatal accidents occur typically compensated because the distance is too small, so there is no room for that hood gives the show a 2002 study published in the British Medical Journal entitled "Designing Road Vehicles for Pedestrian Protection".
Other attempts to save pedestrians from traffic foam box accidents include front airbags four wheel drives and a pop-up system on the Citroën C6 and Jaguar XK, where the hood simply springing up in the moment of the increasing distance to the engine.
Citroën C6 is two thin optical fibers located under a bumper out under the nose of the hood. In a collision crushed the fiber, and an electronic control module calculates the speed and momentum with which the fibers are crushed. Combined with data from an accelerometer under the hood evaluate the electronic control module, the hood must be raised. If so, shoot two springs in the hinges under the windshield hood up by 65 mm in just 40 milliseconds.
Jaguar has developed a similar foam box system for its XK series. But the system is triggered driver must pass a dealer for Jaguar hood back into place. It costs 9,000 dollars - even if the motorist driving too far into the garage. See crash test the vehicle bonnet with doll head

For beehives may have the strangest shapes foam box and configurations, whereas voksbicellernes pattern is imitated in several materials from paper, cardboard, wood, plastic, and aluminum collectively known ..Honeycomb!
No it does not, because honeycomb is integrated into the technician language for this construction principle ...... but really it is inspired by bikagernes material-saving building that only has in common with the technical honeycomb that it is the honeycomb spacer between the two strength-giving layer.
