Abstract: Composite leaf spring is a research hotspot in the field of vehicle lightweighting due to its much better comprehensive performance than steel counterpart. However, the manufacturing process of composite leaf spring is far from mature, leading to high trial production cost and poor product performance stability, which seriously restricts the popularization and application of composite leaf spring. This paper presents an overview of research progress on the manufacturing process of composite leaf spring, including the research results of compression molding, pultrusion, filament winding and resin transfer molding processes. Finally, the development trends and bottleneck problems of manufacturing process of composite leaf spring are summarized.
