Strator XC range
Carbon Fiber Composite
Plastics are lighter, cheaper, and easier to process than metals. But they are still often unable to replace metals, because they are less strong and stiff. Epic Polymers Ltd., Kaiserslautern, Germany, a manufacturer of long-fiber-reinforced plastics (LFT,) addressed this challenge and developed the Strator XC range of composite materials.
These products, based on polyphthalamide (PPA) and polyamide 66 (PA66), are produced using a new carbon fiber technology. They enable far higher mechanical performance to be achieved than with standard carbon fiber reinforcements. For example, these composites have a stiffness of 45 GPa and tensile strength of 350 MPa. They have 30 % lower density than magnesium alloys, while their strength value is 40 % higher than the yield point of magnesium. At elevated temperatures, they also exhibit far lower creep than magnesium and, according to the manufacturer, do not corrode.
Replacement of metal by plastics is of special interest for applications in the automotive sector. Plastic parts cut costs because they require less finishing and can usually be produced without the need for painting. Besides offering a density advantage of 30 %, plastics components can often be designed with thinner walls, which is important for the electronics sector.
