Aluminum can be used to maintain or even increase the size and energy absorption capacity of a vehicle's critical front- and back-end crumple zones for added safety, without increasing overall weight. Aluminum can absorb twice as much crash energy as steel.

What type of design is used for crumple zone?
Crumple zones in high-performance vehicles often follow a honeycomb design, which is stiff in normal conditions but can collapse and crumple in a collision. Next time you're thinking of upgrading your vehicle, consider going for an option with enhanced safety features.
What is the physics behind crumple zones?
Crumple zones add time to the crash by absorbing energy. Crumple zones allow the front of the vehicle to crush like an accordion, absorbing some of the impact of the collision and giving some off in the form of heat and sound.
Why do cars crumple so easily?
Gasoline, when burned in cars, creates tremendous amounts of kinetic energy. ... Thus, the modern idea of "crumple zones" on cars. Crumple zones more allow the car to decelerate more slowly, and to spread the energy of the car in motion around to other structural components of the car.
What materials are crumple zones made of?
Today, a crumple zone in the front and sometimes the rear – coupled with a rigid passenger – compartment are an integral part of the design of every new car. And plastics and composites provide an effective material for use in crumple zones because they collapse on impact.
Where are crumple zones located?
Crumple zones are typically located in the front and rear of a vehicle, and it's designed to crumple or crush upon the impact of a powerful force.
How have crumple zones saved lives?
Crumple zones combined with seat belts, air bags and padded interiors now play a vital role in absorbing the impact of the human body in a collision and reducing harm, particularly to the vital internal organs and the skull.
What are the two types of safety systems called?
There are two types of safety features in vehicles - primary and secondary. Primary safety features are ones that help the driver avoid having a crash (e.g. anti-lock brakes, traction control, electronic stability control).
What is the purpose of vehicle crumple zones quizlet?
Crumple zones work by managing crash energy, absorbing it within the outer parts of the vehicle, rather than being directly transferred to the occupants, while also preventing intrusion into or deformation of the passenger cabin. This better protects car occupants against injury.
What forces are involved in crumple zones?
A change in “momentum” happens when a force is applied to an object that is moving or is able to move. The faster the change in momentum, the greater the force involved. Crumple zones do two things: they absorb energy by the crumpling, and slow down the collision which reduces the change in momentum.
What kind of energy do crumple zones absorb?
Abstract. Crumple zones in any transportation structure are important since they are used to absorb kinetic energy during crash events. Consequently, fatalities among passengers in the compartment can be reduced.
How do crumple zones affect impulse?
Crumple zones minimize the effect of the force in an automobile collision in two ways. By crumpling, the car is less likely to rebound upon impact, thus minimizing the momentum change and the impulse.
What does an airbag do?
Air bags reduce the chance that your upper body or head will strike the vehicle's interior during a crash. To avoid an air-bag-related injury, make sure you are properly seated and remember—air bags are designed to work with seat belts, not replace them.
