PX35 for Automotive Applications

For many automotive industry leaders, ZOLTEK fibers are being used in serial production of several vehicles and applications.The applications range from visible surface parts to structural components. In addition, the selection of manufacturing processes range from well-established processes such as Prepreg compression moulding to most innovative direct fiber placement.

One example of ZOLTEK technology in action includes the development of carbon fiber vehicle parts that outperform glass in impact strength, tensile strength, tensile modulus, and density. You can read the details of KraussMaffei Technologies successfully demonstrating direct compounding injection molding using ZOLTEK PX35 with Laxness Durethan® Polyamide 6 polymer here or download this case study by clicking here. The end result was a molding cycle time of approximately 60 seconds for a large complex part.

Resin Transfer Molding

Another excellent example of the potential uses of ZOLTEK carbon fiber in the automotive industry is The Surface RTM Process. Using ZOLTEK PX35 and a polyurethane (PU) resin system, The Surface RTM Process produces out-of-mold ready to paint carbon fiber components for structural and semi-structural applications. Read more about the process in action here.
