Evonik will showcase its endless fibre-reinforced UD tapes with thermoplastic matrices at JEC World 2017, now distributing them under the VESTAPE brand.
For some years now, Evonik says that tape manufacturers have been using its thermoplastic matrices and now it is manufacturing both glass and carbon fibre tapes using polyamide 12 and specialty high-temperature polyamides. On request, tapes can also be produced using other thermoplastic matrices such as polyamide 6 or PEEK (VESTAKEEP). The tapes are supplied in rolls 80mm and 150mm wide.
In a unidirectional tape, glass or carbon fibres, which are embedded in a thermoplastic matrix, optimally combine their properties so that innovative construction materials result which enable new component design. 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 moulding 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 customised to high-strength endless fibres, which allows production of parts that can be used even in areas exposed to extreme temperatures.
