Munich, Germany - During its customer open day on 7 May 2009, KraussMaffei demonstrated a new process to produce fibre-reinforced polyurethane parts, which combines "excellent mechanical properties with impeccable surface optics," the company said.
The Fibre Composite Spraying (FCS) process involves using reinforcing fibres from an endless roving arc, which are cut to length in a chopper unit, then wetted with polyurethane in a polyurethane spray cone, KraussMaffei said in a 7 May statement.
Typical applications include bodywork parts for utility vehicles such as buses or tractors and wind deflectors or sleeper cabins for trucks.
The company also introduced the Inmould Painting process, a direct process with no barrier coat for Long Fibre Injection Moulding (LFI) parts with a high-gloss surface.
According to KraussMaffei, special filler combinations ensure that the polyurethane matrix completely encapsulates the fibres, thereby eliminating the need for a barrier coat between the paint layer and the fibre-reinforced substrate. The company said the mould technology has also been modified.
In the 2007/2008 business year, ending 30 Sep 2008, the KraussMaffei Group posted sales of more than Euro 1000 million ($1360 million). (RD)
