Ceramic Vs Para Aramid

Kevlar brake pads by lee sallings.

Ceramic vs para aramid.

A para aramid also has an outstanding strength to weight ratio meaning it is. They are aramid ceramic and or aramid metallic pads that can handle higher heat and will not glaze over under heavy towing applications. The pads are scorched to improve cold braking effectiveness. Below infographic shows more details on the difference between meta and para aramid.

Using a slider on disk type wear tester the friction and wear characteristics of aramid fiber reinforced brake pads were studied. In the battle to eliminate the shortcomings of semi metallic brake pads two types of technology in brake pad friction compounds have emerged kevlar and ceramic which are now being used to eliminate some of the problems of noise wear and dusting associated with traditional semi metallic brake. Para aramids like kevlar are highly resistant to chemicals and similar to meta aramids they stand up to extremely high temperatures. The fiber stand up to temperatures up to 500 c.

What are the best brake pads in 2020. Para aramids are far stronger than meta aramids and pound for pound a para aramid fiber is stronger than steel. Averi melcher january 15 2020. The most common example for meta aramid is nomex while for para aramid it is kevlar.

These fibers are created by the the dry jet wet spinning method resulting in a fiber which consists of fully extended liquid crystal chains formed along the fiber axis with. Para aramid composites create little dust and contain no asbestos. Para aramid gloves resist abrasion but the primary motivation for using the fiber is its strong heat resistance. Safeopedia explains para aramid gloves made from para aramid fibers are often used in factories foundries kitchens and other industries where workers are exposed to extremely high temperatures open flames and other tasks requiring flame resistant ppe.

The name is a portmanteau of aromatic polyamide. Aramid fibers are a strong and heat resistant synthetic material. Meta aramid is a polyamide having a high heat resistance while para aramid is a polyamide having a high strength. Para aramids such as kevlar and lower cost alternatives display high tensile strength the maximum stress that a material can withstand and modulus behavior the tendency of a material to deform when force is applied.

The chain molecules in the fibers are highly oriented along the fiber axis. Experiments showed that a tenfold decrease in the wear rate and a halving of the friction coefficient were achieved by the addition of aramid fibers.
