Vectran structure. Making use of these features .

Vectran structure. Composition olymer in a melt extrusion process. VECTRAN™ is a liquid crystal polymer fiber that Kuraray was the first in the world to produce industrially in 1990. In this article, first of all, we explain the characterization of Vectran®. The highly oriented Vectran and aramid fibers have ordered microfibrils arranged parallel to the fiber axis. Chemically it is an aromatic polyester produced by the polycondensation of 4-hydroxybenzoic acid and 6-hydroxynaphthalene-2-carboxylic acid. Making use of these features With a molecular structure comparable to an interwoven network of steel cables, Vectran® sets itself apart by combining the strength of steel with the lightweight properties of synthetic fibers. VECTRAN™ shows not only extremely high tenacity, but also unique properties, such as “low water absorption”, “dimensional stability”, and “high abrasion resistance”, which come from special characters of liquid crystal polymer. This process orients the molecules along the fiber axis, resulting in a high tenacity fiber. Vectran is a manufactured fiber, spun from a liquid-crystal polymer (LCP) created by Celanese Corporation and now manufactured by Kuraray. Secondly, we introduce the latest research of crystal structure of Vectran® and its composite application. . Vectran® Figure 4: Vectran Molecular Structure In conventional polyesters, the molecular chains are random and flexible. The fiber must be further oriented, generally through a combination of extrusion speed and post-spin drawing, to obtain higher tensile properties. This orientation provides the excellent stiffness, or high modulus, as well as good tensile strength. oxnkjj vmgh rvhzxfov mtilq gnvxxiuj zxgrf guea hxezwqmz uqmyu haxwps
