...ing agents or chopped reinforcing fibres, can be incorporated. For the production of moulded parts, only one mould half is required and no mould carrier. Ingo Kleba Thomas Kirsten In processing a reactive multi-component PUR spraying system (type: Multitec, manufacturer: Bayer MaterialScience AG) by the PUR-CSM method, chopped long glass fibres are sprayed together with the PUR mixture into an open mould. The materials are sprayed in multiple layers – solid or foamed, with or without reinforce...

...ld of polyurethane composite spray moulding (CSM), Hennecke, as a Bayer polyurethane technology partner has great process and plant experience; however, the technology is also offered by Cannon and Krauss-Maffei. Multitec spray systems from Bayer MaterialScience are a real innovation because of their versatility and ease of application. Compared with GRP (glass fibre-reinforced polymers), they offer clear productivity advantages and greater versatility. Glass fibre-reinforced systems can also b...

...and CSM technology can do: Composite Spray Moulding (CSM) stands for a whole series of different PU spray moulding processes in which polyurethane can be combined with a wide range of different fibres or fillers. The CSM variant for processing Multitec allows both reinforced and unreinforced PU layers to be sprayed on in any desired combination. Dr. Kleba illustrated this with the pilot application of a premium-class bath tub, designed by Porsche. This is made up of thermoformed acryl sheet and ...

...contrast to the latter, they do not need any solvent whatsoever. Moreover, processing requires considerably less energy. Time- and energy-consuming tempering of the finished parts is not required. PU spray systems such as Multitec (Fig.7) that can be applied in solid or foamed form with or without filler or glass fibers cure at room temperature without additional heat in a matter of minutes, ensuring higher productivity. Conventional glass fiber-reinforced methods using epoxy or unsaturated poly...

...ept from Bayer MaterialScience that combines the PU sandwich approach with PU composite technology permits weight savings of up to 25 %. when producing roof modules for automobiles (Fig. 6). It starts with the Multitec unreinforced sprayable PU system that is applied to an open compression mold and which later determines the surface quality as a solid top layer. Next, a sandwich consisting of a lightweight honeycomb paper core and two outer layers of glass fiber mats is inserted. The reg...

Roof Module: Flexurally and Torsionally Rigid A multi-PU composite also forms the basis of a new BaySystems concept for roof modules combining PU sandwich construction with PU composite technology. First the Multitec PU spray system is sprayed into an open press mold. Then a lightweight honeycomb core and two outer glass-fiber mats are laminated to produce a sandwich that is free of honeycomb at the edges. The sandwich is sprayed with Baypreg F and addition...

The Solon Black 160/05 in-roof module with an “intelligent” system frame based on Bayflex PU foam has already been introduced to the market (Fig. 5). The Multitec PU spray system from BaySystems, Bayer Material-Science”s system department, provides an efficient solution for manufacturing light-weight noise-insulating housings. They exhibit high weather resistance, such as required by the gear nacelles of wind turbines. Trans...
