Технические характеристики
Rectangle rod consisting of carbon fibre and vinyl ester resin.Carbon fibre semi-finished products with light weight, high strength, excellent corrosion and heat resistance and electrical conductivity.
Tolerances:
Deviation in width / height ± 0.2 mm.
Deviation in the straightness max. 2 mm / m. The measured values are generally well below the maximum.
VEC™ Carbon fibre (Vinyl ester resin and carbon fibre)-products are made in the pultrusion / pullwinding method as well as roll-wrapping and liquid resin press moulding (more information about these specific working processes you´ll find at the R&G eWiki).
Vinyl ester is sort of a combination of epoxy and polyester resin. Characteristic properties of vinyl ester are the high temperature resistance and chemical resistance with excellent mechanical properties (stiffness / elongation). Compared to epoxy resins vinyl ester have advantages that make them eminently suitable for processing of semi-finished products (profiles): a low viscosity, i.e. fast and very good impregnation of carbon fiber and a fast, highly controllable curing reaction.
This makes it possible to produce semi-finished products with high quality similar to epoxy as well as economically and thus inexpensive.
