Seat Belt Material Properties

What are seat belt material properties? That we should know what material are seat belts made of firstly.

Webbing is the part of the seat belt in contact with the passenger that receives and softens the shock of an impact. Nylon is among the strongest synthetic fibers, it doesn’t rot as quickly, it doesn’t stretch as much, and woven nylon it is smooth and comfortable to the touch, as it does not leave rough ends of fibers embedded in the weave. So the seat belt webbing material made of polyester and woven from about 300 warp strands and one weft strand. The width of the webbing is about 48mm and has a tensile strength sufficient to support approximately three metric tons. Seat belt material properties are the same as polyester, now let us see the properties of polyester webbing.

There is a reason why safety belts save lives. They are more than just a strap that passengers wrap on their bodies. The following are some of the qualities that webbing made of polyester has:

Very high strength tenacity (Up to 10g/den).
Elongation – up to 25% at break.
Abrasion: excellent resistance to abrasion.
Moisture: has a very low regain of 0.4% making it feel damp very quickly.
Temperature – the melting point is around 260°C and will withstand temperatures above 180°C for some time. It will lose some strength if kept at high temperature for extended periods.
Polyester is very good in low temperatures increasing in strength and reducing elongation.
Polyester webbing is difficult to ignite and tightly woven structures do not burn quickly.
Polyester has excellent resistance to sunlight (one of the best for outdoor use).
Polyester is resistant to most common chemicals.

Most safety belt webbing is made from polyester because it is a high quality material that has high strength tenacity (almost 10g/den). Whenever you are replacing your seat belts, ensure that you purchase seat belt webbing made from this superior material. You can also ask your manufacturer the material they used in your car safety belts. In this case, investing in webbing of high quality may just literally save your life.
