ZHUZHOU, July 16 - Times New Materials' Bogel facility in Zhuzhou has successfully commenced series production of monolithic composite leaf springs, representing a significant milestone in the company's ongoing pursuit of automotive lightweighting solutions.

Suspension system innovation remains a perennial focus within the vehicle chassis engineering community. As a core load-bearing and energy-dissipating component of automotive suspensions, the leaf spring performs critical functions including impact buffering, vibration attenuation, axle guidance, and transmission of forces and moments between the vehicle frame and wheels.

Conventional leaf springs are predominantly manufactured from spring steel via hot-forming processes. In contrast, the newly serial-produced monolithic composite leaf spring from Times New Materials is fabricated from thermosetting resin reinforced with fiberglass, utilizing a compression-molding technique.

Compared with conventional steel counterparts or multi-leaf composite configurations, the monolithic composite leaf spring offers a substantially reduced packaging footprint and a weight saving of 60–70%. This mass reduction directly contributes to enhanced vehicle fuel efficiency and facilitates more convenient assembly, disassembly, and maintenance operations.

The composite leaf spring is inherently free from inter-leaf friction noise, delivering superior NVH (Noise, Vibration, and Harshness) characteristics. It also demonstrates robust resistance to corrosive media—including acids, alkalis, and oils—as well as to hygrothermal aging. With applicability spanning passenger cars, light buses, light-duty trucks, and heavy-duty trucks, the component markedly improves ride stability and ride comfort, thereby elevating the overall driving and passenger experience.

Times New Materials Bogel remains steadfast in its commitment to advancing sustainable mobility. The industrialization of this monolithic composite leaf spring underscores the company's dedication to delivering high-performance, low-emission mobility solutions to its global customer base.
