Suspension system

Leaf spring is one of the important parts of the automobile suspension system. Traditional leaf springs are made of steel materials and are used as elastic elements in different forms on different vehicles. Composite leaf springs use fiberglass-reinforced materials instead of metal materials. The mass of the manufactured component body is significantly lower than that of the metal leaf spring, which can optimize the overall structural design of the suspension, enhance safety, and achieve lightweight. Advantages of Composite Leaf Springs: Compared with traditional steel leaf springs, composite leaf springs have higher elasticity, stronger shock absorption, and higher vibration damping. It can effectively utilize its characteristics during vehicle driving to improve vehicle comfort and smoothness and reduce bumpiness. In addition, the main material of this kind of spring is fiberglass composite material, which has strong fatigue resistance and the fatigue life is more than twice that of ordinary leaf springs. Composite leaf springs also contain more independent glass fibers. The load on the vehicle caused by the rupture of a single glass fiber can be freely transferred to other glass fibers to prevent damage to the load-bearing capacity of the suspension component. Molding Process of Composite Leaf Spring and its Advantages and Disadvantages The development process of composite leaf springs is very complex. Its production processes are divided into winding modeling, high-pressure epoxy resin transfer modeling, SMC molding, RTM process, and others. The winding modeling process is to pre-impregnate the glass fiber composite material, wrap it around the mold,
