• Large Tow Carbon Fiber
• Thermoplastic Tapes
• High Volume Applications



The demand for weight and cost reduction is continuously increasing, especially in the field of transportation and logistics. Reinforced thermoplastics are well known in these fields and are widely used. Currently further decrease of costs and weight is hard to achieve due to the optimization of application specific properties and manufacturing processes. In contrast thermoplastic tapes have a high potential to decrease the weight of the application by high mechanical properties. Nevertheless there are only limited materials available and the know-how of material behavior and process integration is barely available. Furthermore, the tape costs are extremely high and not competitive with the already existing short fiber compounds or metal inserts. This study focuses on the usage of new low costs tapes consisting of a polypropylene matrix and large tow carbon fibers. The use of large tow carbon fibers decrease the material costs drastically. On the other hand, it is very important to achieve a high utilization of the fiber in every step of the process chain, including spreading, impregnation, consolidation, preforming and forming, where the mechanical performance of the carbon fiber tapes are often decreased. As a bottom line the good mechanical properties of carbon fiber need to be translated and transferred into applications. These effects on fiber performance are presented and solutions to overcome the described issues are given. The solutions lead to a decreased process time due to less lofting and a higher fiber utilization, resulting in less fiber breakage and ondulation. These optimizations result in a drastic decrease of weight and costs compared to existing solutions. Applications will be demonstrated where high volume applications and cost efficiency come together and are ready for serial production.
