Toho Tenax will be presenting a new filament yarn as well as net shape carbon fibre preforms at the JEC show next week.
The preforming process, using standard textile forms of either fabric or NCF’s, which are cut and hand laid to construct a perform, has been often identified by Toho Tenax to be a costly and labour intensive process in CFRP part production. Modern industrial part manufacturing processes require higher repeatable quality and cost effective preforming processes instead. Toho Tenax has therefore invested in new production equipment and developed Tenax Net Shape Preforms which can be made by automated placement of multiple carbon fibres using robotic manufacturing equipment.
Toho Tenax has also developed new expertise to manufacture and process functional carbon fibres, which they say ensures reliable mechanical performance. These functional carbon fibres include bound dry fibres for resin transfer moulding, and the mechanical performance of laminates with these preforms is claimed to be greater than that from standard textile preforms.
The application of Tenax Net Shape Preforms is seen to be both as substitution for a standard manual preforms and for the application of new perform concepts which are as yet not possible with current preforming techniques. Currently projects for aerospace and automotive applications are underway.
Additionally, Toho Tenax has developed a new filament yarn type. Tenax STS40 48K is a carbon fibre yarn with 48,000 filaments and Toho Tenax say that it is suitable for high-volume applications such as wind energy or roller applications.
Toho Tenax are on booth G58 at the JEC show.
