The paper addresses three primary areas relative to Composite Springs: A basic primer on Fiber Reinforced Polymer (FRP) materials and their application The core topic discussed is low profile, space efficient Chassis Systems driving the need for Transverse Composite Leaf Springs Longitudinal leaf springs as commonly applied to light trucks and trailers - advantages are highlighted Vehicle requirements will be rolled down to Subsystems and Components. At the component level the use of innovative, lightweight composite materials provides a significant advantage. Besides ensuring technical feasibility, implementation on high volume production vehicles is essential for competing with aluminum and steel materials. Within suspension, Carbon Fiber Reinforced Polymer (CFRP) suspension links as well as lateral and longitudinal leaf springs made from Glass Fiber Reinforced Polymer (GFRP) materials are capable solutions.
