Johns Manville and Comat GmbH Collaborate on RP Pressure Vessels

08 April 2005

Comat GmbH and Johns Manville presented high pressure vessels made of reinforced plastic at the JEC 2005 composite show in Paris. Johns Manville partnered with Comat GmbH, Germany on the development of innovative filament winding applications. Thermoplastic filament winding represents one of the most innovative processes within the composite industry.

Applications for high pressure vessels for the transportation industry are placing very demanding requirements on composite materials. Initial commercialization includes compressed air tanks that are used for the air suspension of luxury cars and trucks as well as for the braking systems in trucks.

Dr. Funck, General Manager of Comat GmbH, Germany, said, “We are pleased to partner with Johns Manville to develop thermoplastic filament winding solutions that offer added value to the industry. First prototypes have been successfully tested by well-known OEMs and full-scale field tests are planned for the near future. ”

The system is build on a plastic inner liner, a reinforced plastic layer made from Johns Manville’s Roving StarRov 473A with world-class mechanical strength for static and dynamic load, and a smooth exterior surface.

The customer benefits of the new system includes a lighter-than-steel weight equivalent to aluminium. JM said that the PP glass laminate (that does not require painting) has excellent corrosion properties, and will not rust like steel.

“Rigorous application of fitness for use and subsequent identification of the critical quality requirements resulted in best-in-class solutions,” said Tim Swales, director of Johns Manville’s Innovation & Commercialization department for the Engineered Products Group. “The strong partnership with Comat GmbH is another demonstration of the JM Experience for our customer.”
