Arkema Inc. (King of Prussia, New York) is featuring its liquid thermoplastic resins, under the brand Elium, which make it possible to produce continuous fiber-reinforced thermoplastic parts.
Also featured is Arkema’s Luperox organic peroxide formulations, specially designed for fast polymerization of Elium resin at room or elevated temperatures. The Elium resin and Luperox organic peroxides system can be used to design structural and aesthetic elements in a number of applications, from automotive and transportation to wind power and construction.
Arkema says composite parts made from Elium resin are 30-50% lighter than the same parts made from steel, but offer the same mechanical performance. Elium resin also is easily cured into complex designs with glass, carbon or other reinforcement fibers through conventional thermosetting technologies like resin transfer molding (RTM), infusion, pultrusion or flex-molding. Because of their thermoplastic properties, Elium resin composite parts are thermoformed and also recyclable.
New developments in other performance resins include Kepstan PEKK, Kynar PVDF, and Rilsan PA resins for automotive and aerospace lightweighting that do not compromise on strength, stiffness, or flame/chemical resistance. Arkema’s Technical Polymers group is also introducing Rilsan matrix composite thermoplastic tapes, for automotive, which provide provide high Tg and good mechanical performance.
The use of continuous fiber in additive manufacturing systems is not trivial, but it is being done. As this fabrication technology evolves and matures, options for applying it in everything from automotive to aerospace to consumer composites will expand tremendously, creating a host of new opportunities for the composites industry. Read here for who is providing what kind of additive manufacturing technology for use in composites fabrication.
Recycling of carbon fiber, glass fiber and — at last — resins, is growing as new players enter the space.
ATL and AFP-based preforming options now abound for processing dry and/or impregnated reinforcements as quickly as 1 minute or less with potential yearly part yields in the millions.
