Hutchinson composite suspension makes waves

French fabricator Hutchinson shows at JEC Europe 2015 an innovative front vehicle suspension, made with fiberglass/epoxy in a resin transfer molding (RTM) process.

Automotive processes, materials and parts were everywhere at JEC Europe 2015 (March 10-12), and one part in particular had show-goers in awe. Automotive and aerospace OEM and Tier supplier Hutchinson (Paris, France), employing more than 35,000 people worldwide in 23 countries, showed at its stand an innovative front suspension, made of fiberglass/epoxy in a resin transfer molding (RTM) process.

Hutchinson’s technical director of the Centre Technique Composite (CTeC), Bertrand Florentz, told CW that the composite “suspension blade” combines four suspension functions in one part: It eliminates the need for helical springs, eliminates wishbones and ball joints, eliminates the need for an anti-roll stabilizing bar, and lastly damps or “filters” road noise caused by the frequencies generated by the tires.
