Leverkusen, Germany - Bayer MaterialScience is to show its polyurethane materials for lightweight yet rigid designs at the JEC composites fair, 27-29 March in Paris, France.
Bayer said the demand for such materials is growing primarily in the mobility and transport sector in order to meet increasingly stringent climate protection requirements and to conserve resources.
The company added that its systems have the potential to reduce costs in the composite materials industry, due to automated application with short cycle and assembly times, which helps to increase the pace of production.
In addition to the established spray technologies, new potential uses are opening up in such areas as resin transfer moulding (RTM), pultrusion and the filament winding process, BMS said.
Bayer gave the example of the engine compartment lining of a convertible currently on the market. This lining is made of aluminium and subjected to extraordinary loads. As part of a feasibility study, BMS demonstrated that the covering can be made from a glass fibre-reinforced polyurethane system such as Multitec Short Fibre.
The covering can be made without modifying the design and BMS said it reduces the weight of the design by more than 20 percent compared with the metal version. This weight saving is achieved without compromising the good mechanical properties, such as stone impact resistance.
Bayer will showcase these and other technologies for the composites industry at the JEC Composites fair in March.
