The bumper of car are made of an aluminum plate 10 mm thick, which is 50% lighter than the steel plate, has an increase in resistance more than 3 times, and it is resistant to corrosion.
Types of bumpers in terms of material used:
Some of them are manufactured to increase aerodynamics or reduce air resistance. They can be customized according to the specifications of the owner of the vehicle. Other modifications may also be included.
The plastic bumpers are the least expensive of the group, since they are easier to manufacture. Unfortunately, they can easily crack due to the impact of the collision.
The best thing about aluminum foam bumpers is that they are lightweight. As such, they reduce the total weight of the vehicle, which can lead to better fuel economy.
Carbon Fiber Bumper:
The carbon fiber bumpers are known for their high impact resistance. Although they are lightweight, they are still durable. They are quite expensive, so they are often found in high-end vehicles. This material is also commonly used in custom bumpers.
Fiberglass is also lightweight and durable. But unlike bumpers carbon fiber options fiberglass are not as expensive. They can be repaired and painted easily. However, it is not as flexible as plastic.
The steel bumpers are known for their resistance. They bear impacts better than other materials. Unfortunately, they can be very heavy.
Importance of the bumper:
The bumpers are made of plastic and have a reinforcing bar made of a strong substance such as SAF aluminum or steel. Some may also contain polypropylene to help absorb energy during impact.
Some bumpers offer better protection than others. Factors that can affect the effectiveness of a bumper include built-in lights and the amount of projections. Bumper standards are regulated by the government; The bumper standard requires that the bumper prevent damage to the body of a vehicle in low impact crashes of less than 5 mph. However, it does not apply to minivans, SUVs and trucks because the bumpers can interfere with the operation of these particular vehicles.
It is not possible to determine the effectiveness of a bumper just because of its appearance and automakers are not required to provide information about its bumpers. However, you can request this information from the manufacturer of your vehicle.
