Initiated by HRC, a new generation of glass-reinforced material leaf springs jointly developed by a number of internationally outstanding companies on the composites industry chain was unveiled at the triennial event in the rubber and plastics industry held in Dusseldorf, Germany-2019 Rolls-Maffei booth. The weight of the glass fiber leaf spring is 60% lighter than that of the traditional metal leaf spring. It can also be reinforced by targeted localization, has high corrosion resistance, and further increases the added value of the product.

The joint development of leaf spring products can be said to be a best practice for the overall coordination of the upstream and downstream of the composite materials industry to maximize the technical advantages of all parties. The parts use HP-RTM (High Pressure Resin Transfer Molding) process to make high glass fiber leaf spring products. The fabric's improved permeability through the design of the fabric allows it to penetrate into multiple plies of the preform. HRC Group members from the United Kingdom-based professional composites engineering design company Engenuity (Ingendi) is responsible for the design and development of leaf springs, Huntsman (Huntsman) provided the matrix system made of epoxy resin, Johns Manville (Jasmaiwei) Glass fiber was provided, Schmidt & Heinzmann made preforms, Chomarat made fabrics, and composite mold expert Alpex designed the HP-RTM process For product molds, Hufschmied (Bobingen, Germany) is responsible for post-mold processing of the parts through milling, and KraussMaffei is responsible for specific project management and final component molding. HRC, as a Tier 1 supplier of composite materials and components for the automotive industry, will vigorously promote and promote it as a key product in the subsequent market development process.

Composite leaf springs have many characteristics such as light weight, large elastic strain, long fatigue life and good safety fracture. According to test data, the service life of composite leaf springs is 5 times that of traditional alloy steel leaf springs, and its re-brightness is less than half of that of traditional leaf springs. At present, well-known OEMs in the world have installed mature production models for loading. Case. In contrast, the domestic use of this product is still at a relatively early stage of exploration. With this pre-research project, the joint development subject established an important theoretical and practical basis for mass production, including material parameters, design parameters, and process paths. In the stagnant environment of the automobile market, perhaps this type of product can provide different major OEMs with surprising ideas for winning in the severe security and performance disputes.
