Solvay targets automotive and aerospace applications at Composites Europe

Solvay, a leading international chemical group is exhibiting at Composites Europe in Düsseldorf, Germany, this week, promoting innovations for the volume and cost efficient manufacture of automotive, aerospace and industrial structures.

The company’s rapid cure thermoset prepregs for automotive applications include MTR 760, specifically developed to manufacture resin impregnated carbon fibre blanks, and MTM 710-1, an epoxy resin prepreg matrix developed specifically for high rate high volume manufacture of structural components using hot compression moulding processes.

MTR 760 resin system

The new MTR 760 resin system is said to offer very good processing properties with rapid cure of 5 minutes at 140°C, a DMA onset TG of 135°C, superior toughness and has excellent dynamic loading characteristics that enable the cured part to pass crash and head impact tests without splintering.

The surface finish of the cured part allows a Class-A paint finish, without the need for any additional surface film, the company reports. Solvay is exhibiting the BMW M4 GTS hood manufactured with MTR 760, which offered a 40% weight reduction when compared to aluminium. This hood recently won the SPE Process Innovation Award as Most Innovative Composite Part.

Depending upon the cure temperature selected, MTM 710-1 can be used to manufacture components with a total cycle time of three minutes. On display is an automotive bulkhead press cured by Penso with MTM 710-1 heavy-tow UD NCF. According to the manufacturer, this material gave the manufacturer the perfect balance of structural integrity and lower total system cost.

Liquid resin infusion technology

The company’s breakthrough liquid resin infusion technology for aerospace primary structure applications includes Solvay’s dry tape TX 1100 and Solvay’s resin system EP 2400. This technology was used to manufacture the wing and wing box of the Russian MC-21 aircraft.

“The MC-21 is the only single-aisle passenger plane whose composite wing structures were manufactured using out-of-autoclave infusion technology and automated fibre deposition. This represents arguably the most technologically advanced wing design in the commercial aerospace sector,” the company explained.

“Solvay’s infusion materials technology allowed the design and manufacture of a large, complex and integrated part structure faster and more efficiently, gaining capacity flexibility and reducing capital intensity.” On Solvay’s stand is a one piece infused demonstrator integrating stringers and skin.
