Answer:
aromatic stacking
Explanation:
Kevlar derives its bulletproof strength from aromatic stacking of its molecules. Although like most compounds having hydrogen bonds, it is quite strong but its unique property which makes it useful due to its strength is as a result of aromatic stacking.
It is an aromatic polymer made up of several units of monomers of terephthalic acid and 1,4-diaminobenzene.
The stack maximizes the hydrogen bonds and the amide linkages which therefore furnishes its unique strength.
