JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Huaxiang R&D Gm, Karsten Brast introduces the progresses of deduction of the processing cost of Huaxiang carbon fiber reinforced polymer (CFRR).
Ningbo Antolin Huaxiang Automobile Products Co., Ltd has some advantages in the auto interior materials. Those advantaged is conduce to accelerate the innovation of product creation and applications. Huaxiang R&D Gm, Karsten Brast introduces the progresses of deduction of the processing cost of Huaxiang carbon fiber reinforced polymer (CFRR).
He said, CFRR is one of the most promising materials for car light structure. But there are obvious obstacles, including the processing cost, spare parts manufacturing and assembly costs, and there is no simulation available in the market.
The automobile industry is developing low cost processing technology and model forming process (including resin accelerating molding), and there is some technologies applied in the production.
However, this requires a large investment and a lot of manpower to support the work. He added, China has relatively low labor costs. It is more suitable to localize CFRR parts mass production. It can reduce the investment cost.
Ningbo Huaxiang latest developed HP compression RTM process can shorten the CFR-R parts cycle time to less than 3 minutes. And the traditional RTM/RIM process would take more than 8 minutes. The company plans to quickly build an Excellence Center for the CFRR R&D.
Brast said: "The production process is a significant cost drivers."
Automotive interior accounts for about 130-150 kg in vehicle total weight. Asia automotive interior weight currently is 20 kilograms lighter than Europe and United States made cars. To maintain this advantage needs to increase the understanding of functional elements (i.e., softer surface, the storage space), to improve occupant safety, and to reduce interior noise.
Plastic accounted for about 10% of the total mass of vehicle, accounted for 75% of the interior mass, thus reducing weight in the interior has "great potential ". Through a combination of thin walled storage, resin additives and composite materials can reduce 5%-50% of the various parts weight. Companies need to spend millions of dollars just to reduce a pound in weight so enterprises are trying to reduce weight by improving the functions.
To change all the materials into plastic may not necessarily be the best solution. The combination of plastic and complementary materials can greatly reduce the vehicle weight, while improves the functions.
