Evonik Develop Endless Fiber-Reinforced UD Tapes for Lightweight Component Construction

2nd March 2017

Fiber-reinforced plastics can create innovative solutions companies looking to save product weight. Chemicals company, Evonik, has developed endless fiber-reinforced UD tapes with thermoplastic matrices to the marketable stage and is now distributing them under the VESTAPE brand.

The company is manufacturing both glass and carbon fiber tapes using polyamide 12 and specialty high-temperature polyamides.

In a unidirectional tape, glass or carbon fibers are embedded in a thermoplastic matrix, optimally combining their properties so that innovative and lightweight construction materials can be produced.

Multiple layers of UD tape in a laminate make up organosheets, which significantly exceed the mechanical properties of metal sheets of similar thickness. Organosheets can be thermoformed and can thus assume various component geometries. They also offer the opportunity to integrate additional functions or components, as the parts can be coated with plastic in an injection molding machine. The matrix is made from specially developed high-performance polymers with a high glass transition temperature and therefore features good heat resistance. The polymers are customized to high-strength endless fibers, which allows production of parts that can be used even in areas exposed to extreme temperatures.

Evonik are due to show the new VESTAPE product at the JEC World in Paris from March 14 to 16, 2017, in Hall 5A, Stand J40.
