Recently, at the results conference hosted by the Industrial Technology Research Institute of China (Mianyang) Technology City, the “basalt fiber composite leaf spring” independently developed by SCZS Basalt Composite Material Tech Corporation has attracted attention. According to Liu Jing, the director of the company’s R & D center, this product has great advantages in terms of cost and performance, and has strong competitiveness in the future automotive parts manufacturing industry.
In recent years, environmentally-friendly and energy-saving automotive lightweight technologies have attracted attention. Fiber-reinforced composite materials have been widely used as a new type of lightweight and high-strength material. The use of FRP instead of steel plates to make leaf springs has become a part of research on lightweight technology for automotive parts Very attractive development direction.
Liu Jing said that leaf springs are the most traditional elastic components in automobile suspension systems. The products released this time use basalt fiber reinforced epoxy resin composite materials as raw materials, and use winding molding, compression molding and other processes to form products and final products. As the basalt fiber composite material has the characteristics of light weight and high strength, while achieving the same performance, the product can reduce weight by 50% -70% compared to traditional leaf springs, which is extremely rare in the lightweight process of other automotive components. Compared with the traditional material E-glass fiber in fiber composite leaf spring, basalt fiber material has obvious advantages in mechanical properties, high temperature resistance, low temperature resistance and corrosion resistance.
In addition to having excellent lightweight effects, basalt fiber composite leaf springs also have the advantages of high fatigue life, large elastic stroke, good comfort, low noise, corrosion resistance, and convenient installation, which can reduce the fuel consumption of the vehicle during driving. As well as carbon dioxide emissions, it has the characteristics of energy saving and environmental protection.
