Kevlar |
Aramid is considered to be a High-Modulus Rope-Making Fiber. The term high-modulus distinguishes a class of synthetic fibers having elastic moduli significantly higher than the conventional fibers as polyester, nylon and Polypropylene. These newer fibers also have significantly higher breaking strengths.
Aramid, the first of these new high-performance fibers, was introduced as duPont Kevlar in the early 1970s. Kevlar was soon successfully used in mooring applications. Problems developed with Kevlar mooring lines employed on the installation barge used for the Lena project (Riewald, 1986). The cause was subsequently identified as axial-compression fatigue, which can occur when tightly constrained aramid fibers are forced into compression.
Nowadays, Kevlar mooring lines of improved designs have subsequently been used successfully on several experimental deep water platform moorings. |
