Ceramic Vs Para Aramid

The name is a portmanteau of aromatic polyamide.

Ceramic vs para aramid.

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. The most common example for meta aramid is nomex while for para aramid it is kevlar. Summary meta vs para aramid. Aramid fibers are a class of heat resistant and strong synthetic fibers they are used in aerospace and military applications for ballistic rated body armor fabric and ballistic composites in marine cordage marine hull reinforcement and as an asbestos substitute.

The pads are scorched to improve cold braking effectiveness. Para aramids like kevlar are highly resistant to chemicals and similar to meta aramids they stand up to extremely high temperatures. The ebc greenstuff 6000 7000 would be recommended for heavier towing 12000 lbs towing as they are reinforced pads and will have even lower brake fade. The chain molecules in the fibers are highly oriented along the fiber axis.

They are aramid ceramic and or aramid metallic pads that can handle higher heat and will not glaze over under heavy towing applications. Averi melcher january 15 2020. Using a slider on disk type wear tester the friction and wear characteristics of aramid fiber reinforced brake pads were studied. Meta aramid is a polyamide having a high heat resistance while para aramid is a polyamide having a high strength.

Aramid fibers are a strong and heat resistant synthetic material. Para aramid gloves resist abrasion but the primary motivation for using the fiber is its strong heat resistance. 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 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.

Para aramid composites create little dust and contain no asbestos. 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. 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. A para aramid also has an outstanding strength to weight ratio meaning it is.
