Technical Information

The Principle of plastics composites is very simple. Fibers e.g. out of glass, carbon or aramid will be embed in resin the so-called matrix. The resulting material compound is a composite. In different working processes small but also very large preforms and complicate geometric parts can be produced with relatively low expenditure. No matter if only a single-part production or a series production, fiber compounds are unique in relation to statical and dynamical characteristics, chemical resistance and surface condition.

The Fibers give the strength to the preform. Dependent on the use, material, diameter and orientation as well as the fiber content in the matrix determine the mechanical and dynamical working charge of the compound. To achieve this a nearly all-over and chemically strong adhesive force between the fibers and the matrix must exist. For that the glass fibers are already coated with coupling agents like e.g. Silane, whilst production.

The Matrix.The reaction resin coats and fixes the fibers so that the fibers are protected against external influences. Moreover influencing forces are spread on the fibers in the requested degree. Modern resin systems can fulfill different requirements: Resistance against chemicals, high surface quality, electrical characteristics, and so on. Decisive for the quality of a preform is also the hardening process. Depending on the used resin and the working method different reaction types and reaction means are used.
