1.1 PUR-CSM for Baypreg? F
PUR-CSM for processing Baypreg? FNatural fibre mats made from flax, sisal, hemp, etc., are compressed into thin-walled, extremely lightweight automotive mouldings using the CSM process and Baypreg? F or similar raw material systems. The products are noted for their high flexural modulus and elevated strength (PUR-CSM Baypreg? Natural Fibre). This group of raw materials can also be used to manufacture sandwich structures consisting of a honeycomb or corrugated core element and glass fibre facings based on a polyurethane matrix on both sides (PUR-CSM Baypreg? Sandwich). When it comes to saving weight while achieving very high levels of flexural strength, PU sandwich composites come second to none. Where necessary, the Sandwich process can be ideally supplemented with the CSM Baydur? variant to provide, for example, additional reinforcement in partial areas. This technique may also be used to create additional stiffening ribs or to selectively strengthen the edge areas of the moulding. This combination of processes can effectively reduce the material input to the necessary minimum. 1.2 PUR-CSM for Baydur?
PUR-CSM for processing Baydur? Today, the well-proven PUR-CSM spraying technique is also used for manufacturing long glass fibre reinforced mouldings in a closed mould. In combination, for example, with the raw material Baydur? of Bayer MaterialScience (PUR-CSM Baydur?). Instead of using pre-fabricated fibre mats, glass rovings are dispensed from a reel and cut before processing. Polyurethane mixture is See full-size image sprayed into the open mould, with the chopped glass fibres being externally added to the PU spray jet. The moulding is then formed after curing in the closed mould. The irregular distribution of the glass fibres imparts a high mechanical strength to the finished part in all load directions. 2 KraussMaffei
