Composite
The automotive market is constantly evolving, and the search for more efficient and durable solutions has driven the development of new technologies.
Keeping pace with this transformation, Marchetti introduces the Front Sprinter Composite Spring to the market, a solution that combines innovation and high performance to meet the demands of current and future mobility.
Developed using composite materials made from fibers and resin, the Composite Spring represents a significant advancement in suspension systems, offering benefits that go beyond weight reduction and providing greater comfort, safety, and durability.
Technology:
Technology that enables efficient load distribution, making fiberglass a technical alternative to metal in applications where weight reduction and durability are strategic factors.
Up to 60% lighter than steel springs
One of the main highlights of the Composite Spring is its weight reduction. Made from composite material, it can be up to 60% lighter than a metal spring, contributing to suspension system efficiency and improved vehicle performance.
This weight reduction directly contributes to:
- Greater vehicle efficiency;
- Reduced fuel consumption;
- Lower CO₂ emissions;
- Improved suspension system performance;
- Longer component service life.
Durability:
Composite materials offer high specific strength, meaning they provide an excellent strength-to-weight ratio.
In addition, their natural flexibility provides greater fatigue resistance, an essential characteristic for components subjected to constant stress. As a result, the Composite Spring delivers greater durability while maintaining its efficiency even under severe operating conditions.
Greater comfort and lower noise levels
In addition to strength and lightweight properties, the technology used in the composite material contributes to a more comfortable ride. Its vibration absorption capacity reduces noise transmission and improves the driving experience for both drivers and passengers.
Safety and stability:
Safety is one of the key pillars in the development of the Composite Spring. In the event of failure, the material behaves differently from steel. The component breaks into pieces and gradually loses its load-bearing capacity, providing an important safety feature for the system and contributing to operational safety.
Furthermore, suspension stability and efficiency are maintained throughout the component's service life, providing greater vehicle reliability.
Composite Spring X Metal Spring
Composite Spring (Fibers and resin):
- Up to 60% lighter than steel springs;
- High specific strength;
- High fatigue resistance;
- Greater comfort and lower noise levels;
- Ideal for applications requiring weight reduction and greater efficiency.
Metal Spring (Steel):
- Excellent performance in high-load and heavy-duty applications;
- Well-established solution in the market;
- Strong presence in traditional and more cost-sensitive applications.
The Composite Spring emerges as a strategic solution for applications where weight reduction, durability, and efficiency deliver real long-term benefits.
Trends
The evolution of mobility points toward increasingly efficient vehicles. Modern models and special applications already demonstrate a strong trend toward the use of composite materials in their components.
While metal springs continue to dominate traditional and high-load applications, composite springs represent an important path toward the next generation of suspension systems.
The market evolves. And Marchetti evolves with it. With more than eight decades of tradition and continuous investment in technology, the company presents a solution that reinforces its commitment to innovation and the development of products aligned with the automotive industry's evolving demands.
