Carbon-fiber/phenolic compounds beat wear.At this month's K 2004 show in Dusseldorf, Vyncolit of Belgium (U.S. office in Farmington Hills Far·ming·ton Hills A city of southeast Michigan, an industrial suburb of Detroit. Population: 81,400. , Mich.) introduced Vyntec moldable phenolic phe·no·lic adj. Of, relating to, containing, or derived from phenol. n. Any of various synthetic thermosetting resins, obtained by the reaction of phenols with simple aldehydes and used as adhesives. compounds reinforced with short carbon fibers. These products are said to provide properties equal to or better than those of more costly PEEK and PEI (GE's Ultem) thermoplastics reinforced with carbon fibers. Vyntec's tribological (wear) properties are said to be particularly impressive: Tests of one grade showed only 3% to 6% as much wear as carbon-fiber/PEEK. Vyntec reportedly retains a low coefficient of friction coefficient of friction n. pl. coefficients of friction The ratio of the force that maintains contact between an object and a surface and the frictional force that resists the motion of the object. at high temperatures. Heat resistance is another advantage of this thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic. . It maintains its surface and mechanical properties in continuous use at 150 C (302 F), says Vyncolit. In addition, Vyntec has low density--1.35 to 1.55 g/cc--giving a high stiffness/weight ratio.
