Styrene-free production of composites

Due to their light weight with high strength and stiffness, fiber-reinforced plastics are suitable for lightweight construction and – among others – used for commercial- and rail vehicles.

Often, such components are made of fiberglass-reinforced styrene-containing polyester resins and are laminated manually. This technique has considerable drawbacks – it strains people and the environment with toxic fumes of styrene and has a high share of manual work and long process and response times.

Environmentally friendly polyurethane spray

In collaboration with Krauss-Maffei, different material manufacturers and the Technical University of Chemnitz, the company Lätzsch GmbH Kunststoffverarbeitung from Thierbach has developed an environmentally friendly alternative to product maturity – an innovative spray technology for glass fiber reinforced polyurethane resins (PUR), which requires neither styrene nor solvent.

During the fiber-composite spraying (FCS), fast curing, multi-part polyurethane is sprayed together with reinforcing fibers into an open mold. Just five minutes later the part can be shaped, an elaborate venting and finishing is no longer necessary.

Fewer working steps, a simple processing and high flexibility are further advantages of the new procedure which can be used in vehicle manufacturing, shipbuilding and container construction as well as in medical engineering. Also, the structural component reinforcement, for example, of injection molded parts, is possible.
