We are glad to announce that Promote now has a new Rev 2.0 bumper made of Kevlar re-inforcement. You now have an option to choose the Kevlar version at RM850 which is made upon request. With Kevlar re-inforcement, a full layer of Kevlar is re-inforced to the bumper with the existing design, whereby improving Promote's durability to a much higher level.
This is ideal for those who want the ultimate in looks and quality.
Here is a short explanation on Kevlar taken from http://www.lbl.gov/MicroWorlds/Kevlar/
FACTS
Under water, Kevlar is 20 times stronger than steel.
These Kevlar cables are supporting a sonar facility that the U.S. Navy uses to find out how much noise submarines make.
Police wear bulletproof vests made of Kevlar.
I WONDER WHAT MAKES KEVLAR®* SO STRONG ??
CLUE #1: KEVLAR is a long chain-like molecule known as a polymer, which consists of repeating units called monomers.
CLUE #2: A Kevlar fiber is an array of molecules oriented parallel to each other like a package of uncooked spaghetti. This orderly, untangled arrangement of molecules is described as a crystalline structure. Crystallinity is obtained by a manufacturing process known as spinning, which involves extruding the molten polymer solution through small holes. The crystallinity of the Kevlar polymer strands contributes significantly to Kevlar's unique strength and rigidity.
CLUE #3: Kevlar is a polyaromatic amide. That is, it contains aromatic and amide groups. Other polymers with a high breaking strength often contain one or both of these molecular groups.
CLUE #4: The individual polymer strands of Kevlar are held together by hydrogen bonds that form between the polar amide groups on adjacent chains.
CLUE #5: The aromatic components of Kevlar polymers have a radial (spoke-like) orientation, which gives a high degree of symmetry and regularity to the internal structure of the fibers. This crystalline-like regularity is the largest contributing factor in the strength of Kevlar. Only with bright synchrotron radiation could the secret strength of Kevlar be revealed.
As you have discovered, there are many components that contribute to the strength of Kevlar, including the fact that Kevlar is a polymer containing aromatic and amide molecular groups. When the molten Kevlar is spun into fibers, the polymers have a crystalline arrangement, with the polymer chains oriented parallel to the fiber's axis. The amide groups are able to form hydrogen bonds between the polymer chains, which act like glue holding the separate polymer chains together. The most recent XANES images confirm that the aromatic components of Kevlar have a radial (spoke-like) orientation, which allows for a high degree of symmetry and order.
