WebJan 5, 2024 · Carbon fiber-reinforced polymers (CFRPs) include epoxy, polyester, nylon and vinyl. However, the fibers often include glass or aluminum in addition to carbon. This material variation provides strength and rigidity to CFRP. The properties of CFRP are dependent on the ratio of fiber to polymer, the types of additives and the matrix structure. WebFor this reason, and because the backbone of nylon is so regular and symmetrical. Its chemical structure is shown in Figure 1. Hydrogen bonding is the most significant intermolecular force in nylon. One nylon chain’s nitrogen-bonded hydrogen atoms will form a very strong hydrogen bond with another nylon chain’s carbonyl oxygen atoms.
